description: We analyse the impact of the inverse square law fall-off of the energy density in a charged isotropic spherically symmetric fluid. Initially we impose a linear barotropic equation of state $p=αρ$ but this leads to an intractable differential equation. Next we consider the neutral isothermal metric of Saslaw, Maharaj and Dadhich (1996) in an electric field and the usual inverse square law of energy density and pressure results thus preserving the equation of state. Additionally, we discard a linear equation of state and endeavour to find new classes of solutions with the inverse square law fall off of density. Certain prescribed forms of the spatial and temporal gravitational forms result in new exact solutions. An interesting result that emerges is that while isothermal fluid spheres are unbounded in the neutral case, this is not so when charge is involved. Indeed it was found that barotropic equations of state exist and hypersurfaces of vanishing pressure exist establishing a boundary in practically all models. One model was studied in depth and found to satisfy other elementary requirements for physical admissability such as a subluminal sound speed as well as gravitational surface redshifts smaller than 2. The Buchdahl (1959), Bohmer and Harko (2007) and Andreasson (2009) mass-radius bounds were also found to be satisfied. Graphical plots utilising constants selected from the boundary conditions established that the model displayed characteristics consistent with physically viable models.

description: Anomalous transport in a tilted periodic potential is investigated numerically within the framework of the fractional Fokker-Planck dynamics via the underlying CTRW. An efficient numerical algorithm is developed which is applicable for an arbitrary potential. This algorithm is then applied to investigate the fractional current and the corresponding nonlinear mobility in different washboard potentials. Normal and fractional diffusion are compared through their time evolution of the probability density in state space. Moreover, we discuss the stationary probability density of the fractional current values.

description: California is home to the world's largest movie clusters. It grew out of the need to extend beyond New York's confined environment. The opportunities that lay ahead were carefully planned and exploited. For Western Massachusetts to learn from this example it will have to discover a niche that can be marketed as truly worthy of attracting businesses away from established clusters. This will require a top-down approach from government bodies to ensure that a successful cluster fits wit the New England lifestyle. Current opportunities exist within factory towns that have available old mill buildings and infrastructure. Unfortunately the establishment of a film cluster will require a huge one-time investment by the government to convince others to invest their capital here. In the example of Miami, many different film clusters have developed from the branding of the city. There wasn't a general idea of Miami's film culture until the television program Miami Vice placed the city on the world map. Both Massachusetts and Miami must work hard to integrate the potential development of film clusters by working hard to secure tax breaks to lure companies away from Toronto. The film cluster there is rapidly becoming established, especially in this depressed economic environment. This will prove to be a stiff competitor, but it is not too late. Cutting the main costs of taxes, accommodation/living expenses while raising the profile of these regions is the first hurdle to be cleared. Only when this is done will a successful clustering strategy grow.

description: Petroleum from leaking underground storage tanks (LUSTs) can contaminate local soil, and surface and groundwater. In some cases this can pose health risks to the surrounding population. Focusing on single family home sales from 1996-2007 in three Maryland counties, we use a hedonic house price model to estimate the willingness to pay to live father away from LUST sites. Particular attention is given to how property values are affected by leak and cleanup activity at a LUST site, the severity of contamination, the presence of a primary exposure path (i.e., private groundwater wells), and publicity surrounding a LUST site. The results suggest that although the typical LUST site may not significantly affect nearby property values, more publicized (and more contaminated sites) can impact surrounding home values by more than 10%.

description: The Andean cock-of-the-rock (Rupicola peruvianus) belongs to the Neotropical family Cotingidae, inhabiting the Andean mountains from Venezuela to Bolivia. Despite being a recognised and iconic species, most breeding studies of this bird have focused on its display behaviour at communal ‘leks’ rather than its basic nesting biology. Here, we present novel data on incubation behaviour and detailed descriptions of nests, eggs, and nestling development, with the first photographic evidence of nestlings being fed with vertebrates. We found 38 cup-shaped nests located along rocky walls near rivers or creeks in Peru, Ecuador, and Colombia. Nests were placed on rocky indentations along rivers, creeks, and waterfalls. The mean clutch size was two eggs. Eggs were beige with brown/green spots mainly located towards the wider end. Eggs measured 46.7 ± 1.2 mm by 32.7 ± 0.3 mm and weighed 25.6 ± 0.9 g. The incubation and nestling period lasted 26.0 ± 1.3 and 40.0 ± 2 days, respectively. During the incubation period, the female was the only parent attending the nest, with an average daily nest attentiveness of 87.3 ± 6.6%. The nestlings grew at a logistic curve rate (K) of 0.135 ± 0.005 g and kept their body temperature constant at 39.3°C only after day 30 of development. Detailed natural history accounts of the nest locations are necessary to generate long-term monitoring and successful conservation strategies of Neotropical species, especially for large frugivorous birds such as R. peruvianus that have long nesting cycles, specific nesting locations and are highly sensitive to forest fragmentation.

description: We present results from deep and very spatially extended CTIO/DECam $g$ and $r$ photometry (reaching out to $\sim$ 2 mag below the oldest MSTO and covering $\sim$ 20 deg$^2$) around the Sextans dSph. We use this data-set to study the structural properties of Sextans overall stellar population and its different stellar evolutionary phases, as well as to search for signs of tidal disturbance from the MW, which would indicate departure from dynamical equilibrium. We perform the most accurate structural analysis to-date of Sextans' stellar components by applying Bayesian MCMC methods to the individual stars' positions. Surface density maps are built by decontaminating the sample through a matched filter analysis of the CMD, and then analysed for departures from axisymmetry. Sextans is found to be considerably less spatially extended than early studies suggested. No significant distortions or tidal disturbances are found down to a surface brightness of $\sim$ 31.8 mag/arcsec$^{-2}$ in V-band. We identify an overdensity in the central regions that may correspond to previously reported kinematic substructure(s). In agreement with previous findings, old $\&$ metal-poor stars such as BHB stars cover a much larger area than stars in other evolutionary phases, and bright BSs are less spatially extended than faint ones. However, the different spatial distribution of bright and faint BSs appears consistent with the general age/metallicity gradients found in Sextans' stellar component. This is compatible with BSs having formed by evolution of binaries and not necessarily due to the presence of a central disrupted globular cluster, as suggested in the literature. We provide structural parameters for the various populations analyzed and make publicly available the photometric catalogue of point-sources as well as a catalogue of literature spectroscopic measurements with updated membership probabilities.

description: Abstract: "Many object-oriented methods have assumed class-based approaches, without considering prototype-based ones. Some authors, while admitting prototypes as a useful concept, only envision their application in early phases of systems development. Others consider only the use of the prototype concept in programming environments and not with respect to the whole systems development process. We propose that these omissions are neither necessary nor useful and often can be harmful, in that methods grounded in purely class-based assumptions do not reflect the nature of problems inherent in modeling. In this paper, we argue, using the principle of limited reduction, that both class-based and prototype-based approaches should be used in object-oriented methods, respectively for controlling complexity, and capturing enough detail for evolution."

description: 734 steers, weighing 286 kg, were used during a 118-day grazing period, after which 640 were placed in a feedlot for finishing (average of 121 days, range of 111 to 133 days) to measure the main effects and interactions of 2 pasture deworming treatments (negative control, strategically dewormed with fenbendazole) and 2 feedlot deworming treatments (negative control, dewormed with fenbendazole) on faecal egg counts, abomasal worm counts and abomasal pathology. Seven to 10 abomasa from steers on each of the 4 pasture-feedlot treatments (pasture control-feedlot control; pasture control-dewormed in the feedlot; strategically dewormed on pasture-feedlot control; strategically dewormed on pasture-dewormed in the feedlot) were selected at slaughter to determine total worm counts, and to evaluate gross pathology and histopathology of the abomasal mucosa. Pasture deworming with fenbendazole (FBZ) in a strategic programme on days 0, 28 and 56 reduced adult and L4 and EL4 larval stages of Ostertagia ostertagi and adult and L4 stages of Trichostrongylus axei residing in the abomasum at slaughter. Feedlot deworming with FBZ reduced L4 and EL4 stages of O. ostertagi and adult and L4 stages of T. axei. An interaction between pasture deworming treatment and feedlot deworming treatment showed that pasture deworming had a significant effect on reducing the number of Trichostrongylus adult parasites, which was not further reduced by feedlot deworming. Strategic pasture deworming with FBZ followed by FBZ administration at the beginning of the finishing period reduced total O. ostertagi, T. axei and Haemonchus adult and larval stages by 99.13%, compared with untreated controls. There was no relationship between faecal egg counts and total worm counts. Gross pathology showed that strategic deworming on pasture reduced the mean abomasal lesion score at slaughter. An interaction between pasture treatment and feedlot treatment showed that feedlot deworming of pasture control steers reduced mean histopathology score, while feedlot deworming of steers strategically dewormed on pasture had no impact. Distribution of histopathology scores showed that strategic deworming on pasture resulted in more steers without histopathological changes to the abomasal mucosa and fewer steers with higher histopathology scores.

description: We study the behavior of monogamy deficit and monogamy asymmetry for Einstein-Podolsky-Rosen steering of Gaussian states under the influence of the Hawking effect. We demonstrate that the monogamy of quantum steering shows an extreme scenario in the curved spacetime: the first part of a tripartite system cannot individually steer two other parties, but it can steer the collectivity of the remaining two parties. We also find that the monogamy deficit of Gaussian steering, a quantifier of genuine tripartite steering, are generated due to the influence of the Hawking thermal bath. Our results elucidate the structure of quantum steering in tripartite quantum systems in curved spacetime.

description: Shale gas fracturing flowback fluid contains various degradation difficulty organic compounds after hydraulic fracturing. A hybrid treatment method was developed for treating flowback and produced water (FPW) using pre-treatment (NaClO) followed by the expanded granular sludge bed (EGSB) and moving bed biofilm reactor (MBBR). Gas chromatography–mass spectrometry (GC-MS) was employed to detect organic composition in the FPW, the pre-treated FPW, EGSB and MBBR effluent. FPW had high chemical oxygen demand (COD) (3278 mg/L) and the majority of organic compounds in the FPW composed of alkanes and heteroatomic compounds with polymers and polarity. 20% COD removal was achieved after adding 5 g/L of NaClO in FPW (pH = 7, stirring for 20 mins) as pre-treatment and > C30 alkanes in FPW were decomposed a lot in the pre-treatment process. The pre-treated FPW was diluted (volumetric ratio of 20%/50%) with synthetic wastewater/pure water. In the final stage of operation, Cl− and COD concentration of influent to EGSB-MBBR system was around 7000 ± 100 mg/L and 3000 mg/L. EGSB-MBBR system achieved 93.84% COD removal rate, in which EGSB dominated COD removal (>80%). According to the GC-MS results, EGSB had an increase of C11-C30 compounds and a decrease of less C1-C10 content due to the consumption of  > C30 compounds and low molecular weight (LWM) compounds. Meanwhile, aerobic microorganisms in MBBR metabolized LWM organics which contributed a lot to the COD removal (25.06∼68. 22%). The results indicated that the pre-treatment and biological EGSB-MBBR system could be an efficient option used for FPW treating.

description: Purely gravitational perturbations are considered in a thin rotating disk composed of several gas and stellar components. The dispersion relation for the axisymmetric density waves propagating through the disk is found and the criterion for the local axisymmetric stability of the whole system is formulated. In the appropriate limit of two-component gas we confirm the findings of Jog & Solomon (1984) and extend consideration to the case when one component is collisionless. Gravitational stability of the Galactic disk in the Solar neighborhood based on the multicomponent instability condition is explored using recent measurements of the stellar composition and kinematics in the local Galactic disk obtained by Hipparcos satellite.

description: We extend an above barrier analysis made with the Schrodinger equation to the Dirac equation. We demonstrate the perfect agreement between the barrier results and back to back steps. This implies the existence of multiple (indeed infinite) reflected and transmitted wave packets. These packets may be well separated in space or partially overlap. In the latter case interference effects can occur. For the extreme case of total overlap we encounter resonances. The conditions under which resonance phenomena can be observed is discussed and illustrated by numerical calculations.

We introduce the unique maximal part of a multifunction which is defined on the quotient given by an equivalence relation. Measurability of this part of a multifunction is proven in a special case. We show how these results apply to the spectral theory of measurable families of closed linear operators.

Effect of castration on weight gain of beef calves

Publisher: name: The Bovine Practitioner
Year: 2000

description: Many management practices can be utilized to maximize weight and increase value of calves at weaning. Combining the two management practices of castration and implanting male calves allows producers to maximize weaning weights and avoid discounts for intact males. Crossbred bull calves were randomly assigned at birth to 1 of 3 treatment groups: castrated (n = 22), banded (n = 18) or left intact (n = 20). Calves that were castrated or banded within 24 h after birth received a zeranol implant at that time. Calves in the intact group were castrated at 150 days of age and then implanted, and the calves in the other 2 treatment groups were re-implanted at that time. There were no differences in weaning weight, average daily gain (ADG) or weight per day of age between the 3 treatment groups. Castrating calves shortly after birth reduced stress on the animal compared to castration at a older age (day 150 to weaning). Also, early castration may be more acceptable as an animal welfare issue. It is concluded that combining castration and implanting allows producers to maximize weaning weight of calves as well as reduce the stress of castration at an older age.

description: We present a study of the dynamical behavior of a Ziff-Gulari-Barshad model with CO desorption and lateral diffusion. Depending on the values of the desorption and diffusion parameters, the system presents a discontinuous phase transition between low and high CO coverage phases. We calculate several points on the coexistence curve between these phases. Inclusion of the diffusion term produces a significant increase in the CO_2 production rate. We further applied a square-wave periodic pressure variation of the partial CO pressure with parameters that can be tuned to modify the catalytic activity. Contrary to the diffusion-free case, this driven system does not present a further enhancement of the catalytic activity, beyond the increase induced by the diffusion under constant CO pressure.

Subjects: subject: Computational Physics (physics.comp-ph)
subject: FOS: Physical sciences

description: This paper explores the use of a discrete singular convolution algorithm as a unified approach for numerical integration of the Fokker-Planck equation. The unified features of the discrete singular convolution algorithm are discussed. It is demonstrated that different implementations of the present algorithm, such as global, local, Galerkin, collocation, and finite difference, can be deduced from a single starting point. Three benchmark stochastic systems, the repulsive Wong process, the Black-Scholes equation and a genuine nonlinear model, are employed to illustrate the robustness and to test accuracy of the present approach for the solution of the Fokker-Planck equation via a time-dependent method. An additional example, the incompressible Euler equation, is used to further validate the present approach for more difficult problems. Numerical results indicate that the present unified approach is robust and accurate for solving the Fokker-Planck equation.

The Initial Mass Function of Low-Mass Stars and Brown Dwarfs in Taurus

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: By combining deep optical imaging and infrared spectroscopy with data from the Two-Micron All-Sky Survey (2MASS) and from previous studies (e.g., Briceno et al.), I have measured the Initial Mass Function (IMF) for a reddening-limited sample in four fields in the Taurus star forming region. This IMF is representative of the young populations within these fields for masses above 0.02 Msun. Relative to the similarly derived IMF for the Trapezium Cluster (Luhman et al.), the IMF for Taurus exhibits a modest deficit of stars above one solar mass (i.e., steeper slope), the same turnover mass (~0.8 Msun), and a significant deficit of brown dwarfs. If the IMF in Taurus were the same as that in the Trapezium, 12.8+/-1.8 brown dwarfs (>0.02 Msun) are expected in these Taurus fields where only one brown dwarf candidate is found. These results are used to test theories of the IMF.

description: We study the stellar populations of bulges of Milky Way-like (MW-like) galaxies with the aim of identifying the physical processes involved in the formation of the bulge of our Galaxy. We use the semi-analytic model of galaxy formation and evolution SAG adapted to this aim; this kind of models can trace the properties of galaxies and their components like stellar discs, bulges and halos, but resolution limits prevent them from reaching the scale of stellar populations (SPs). Properties of groups of stars formed during single star formation events are stored and tracked in the model and results are compared with observations of stars in the galactic bulge. MW-like galaxies are selected using two different criteria. One of them considers intrinsic photo-metric properties and the second is focused on the cosmological context of the local group of galaxies (LG). We compare our model results with spectroscopic and photometric stellar metallicity distributions. We find that 87% of stars in bulges of MWtype galaxies in our model are accreted and formed in starbursts during disc instability events. Mergers contribute to 13% of the mass budget of the bulge and are responsible for the low metallicity tail of the distribution. Abundance ratios of α elements with respect to iron, [α/Fe], are measured in SPs of model galaxies. The patterns found in the model for SPs with different origins help to explain the lack of a gradient of [α/Fe] ratios in observed stars along the minor axis of the bulge.

description: When multiple processor (CPU) cores and a GPU integrated together on the same chip share the off-chip main memory, requests from the GPU can heavily interfere with requests from the CPU cores, leading to low system performance and starvation of CPU cores. Unfortunately, state-of-the-art application-aware memory scheduling algorithms are ineffective at solving this problem at low complexity due to the large amount of GPU traffic. A large and costly request buffer is needed to provide these algorithms with enough visibility across the global request stream, requiring relatively complex hardware implementations. This paper proposes a fundamentally new approach that decouples the memory controller's three primary tasks into three significantly simpler structures that together improve system performance and fairness, especially in integrated CPU-GPU systems. Our three-stage memory controller first groups requests based on row-buffer locality. This grouping allows the second stage to focus only on inter-application request scheduling. These two stages enforce high-level policies regarding performance and fairness, and therefore the last stage consists of simple per-bank FIFO queues (no further command reordering within each bank) and straightforward logic that deals only with low-level DRAM commands and timing. We evaluate the design trade-offs involved in our Staged Memory Scheduler (SMS) and compare it against three state-of-the-art memory controller designs. Our evaluations show that SMS improves CPU performance without degrading GPU frame rate beyond a generally acceptable level, while being significantly less complex to implement than previous application-aware schedulers. Furthermore, SMS can be configured by the system software to prioritize the CPU or the GPU at varying levels to address different performance needs.

description: The potential association between seroconversion to respiratory disease agents and isolation from transtracheal wash fluids (TTW) was investigated in pneumonic dairy calves <3 months of age. Naturally infected calves from 18 commercial dairy farms were used. At least one respiratory pathogen was cultured from the TTW of each calf. Blood samples were collected at the time of diagnosis and 3 weeks later. Most calves had evidence of maternal antibodies at 2 days of age to the same pathogens isolated from the TTW at the time of respiratory disease diagnosis. Evidence of an active immune response (seroconversion) to the organism in the TTW was a specified rise in titre between paired serum samples. False-negative results, i.e. failure to seroconvert to the organism isolated in the TTW, were seen in 8 of 9 (89%) calves with bovine diarrhoea virus in their TTW, 43 of 75 (57%) calves with Mycoplasma spp. in their TTW, 20 of 53 (38%) calves with Pasteurella multocida, 4 of 16 (25%) calves with Pasteurella haemolytica, and 5 of 13 (38%) calves with Haemophilus somnus isolates in their TTW. Reliance on paired-serological testing to identify the respiratory pathogens present in the respiratory tract of clinically pneumonic dairy calves <3 months of age is not recommended.

Fick's Law in Non-Local Evolution Equations
Creators: name: Boccagna, Roberto
Publisher: name: arXiv
Year: 2017
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We study the stationary non-local equation which corresponds to the energy functional of a one-dimensional Ising spin system, in which particles interact via a Kac potential. The boundary conditions share the same sign and both lie above the value $m^*\left(β\right)=\sqrt{1-1/β}$, which divides the metastable region from the unstable one, the inverse temperature being fixed and larger than the critical value $β_c=1$. Due to the non-equilibrium setting, a non zero magnetization current, which scales with the inverse of the size of the volume $\varepsilon^{-1}$, do flow in the system. Here $\varepsilon^{-1}$ also represents the ratio of macroscopic and mesoscopic length. We show that for $\varepsilon>0$ small enough, the stationary profile has no discontinuities so that no phase transition occurs; although expected when the magnetizations are larger than $m_β$, this turns out to be non trivial at all in the metastable region. Moreover, when $\varepsilon^{-1}\to\infty$, the solution converges to that of the corresponding macroscopic problem, i.e. the local diffusion equation. The validity of the Fick's law in this context is then established.

description: In a recent remarkable experiment [P. Roushan et al., Nature Physics 13, 146 (2017)], a spin current in an architecture of three superconducting qubits was produced during a few microseconds by creating synthetic magnetic fields. The life-time of the current was set by the typical dissipative mechanisms that occur in those systems. We propose a scheme for the generation of permanent currents, even in the presence of such imperfections, and scalable to larger system sizes. It relies on striking a subtle balance between multiple nonequilibrium drives and the dissipation mechanisms, in order to engineer and stimulate chiral excited states which can carry current.

Evaluation of the early conception factor dip stick test in dairy cows between days 11 and 15 post-breeding

description: A field study was conducted between February and November 1995 using 139 Holstein cows to determine the accuracy and the usefulness of the ECF Dip Stick Test performed between days 11 and 15 post-breeding. Results of the ECF tests were compared to pregnancy diagnosis after 25 days post-breeding using ultrasonography and transrectal palpation. The apparent conception rate of the study population based on transrectal palpation was 38%. The ECF test sensitivity, specificity, positive and negative predictive values were 81%, 26%, 40% and 69%, respectively. The Kappa value (0.06; 95%CI -0.19 to 0.30) demonstrated no agreement between the ECF test and the final pregnancy status of dairy cows. These results would indicate that the ECF test is not a good predictor of pregnancy because the proportion of false positive results was high at 46% (64/139). Furthermore, the accuracy of the test to detect open cows is not acceptable with the high proportion of false negative tests of 31% (10/32). This finding would indicate that 19% (10/53) of the cows diagnosed pregnant rectally were misdiagnosed as non-pregnant by the ECF test. Finally, many factors such as the incubation time, the personal assessment of the test reaction and the source of light can also affect the ECF test reading. Based on the current technology, the authors would not recommend the use of the ECF test to help dairy producers reduce non-productive days.

description: In collaboration with a student team from the Department of Landscape Architecture and Regional Planning at the University of Massachusetts Amherst, the Community Development Corporation of Lee explored the potential reuse of an industrial parcel owned by Lane Construction Corporation in Lee, Massachusetts. The 243-acre property is currently in operation as a gravel and sand operation and asphalt processing plant in Lenox Dale, north of Lee center. Identified as one of the largest industrial zoned parcels in New England, the Lane site has great economic potential in the future development of the town and the surrounding region. However, the site also presents significant environmental challenges including its location near sensitive natural resources such as the bordering Housatonic River and an underlying major aquifer. Consequently, future recommendations for the property will need to consider site-specific environmental issues as well as cultural issues such as the economic and recreational needs of Lee and the surrounding Berkshire County. Recommendations for the site also require sensitivity to the Town of Lee and the current proprietary conditions of Lane Construction Corporation.

description: An orbital-angular-momentum (OAM) mode-group multiplexing (MGM) scheme based on a graded-index ring-core fiber (GIRCF) is proposed, in which a single-input two-output (or receive diversity) architecture is designed for each MG channel and simple digital signal processing (DSP) is utilized to adaptively resist the mode partition noise resulting from random intra-group mode crosstalk. There is no need of complex multiple-input multiple-output (MIMO) equalization in this scheme. Furthermore, the signal-to-noise ratio (SNR) of the received signals can be improved if a simple maximal ratio combining (MRC) technique is employed on the receiver side to efficiently take advantage of the diversity gain of receiver. Intensity-modulated direct-detection (IM-DD) systems transmitting three OAM mode groups with total 100-Gb/s discrete multi-tone (DMT) signals over a 1-km GIRCF and two OAM mode groups with total 40-Gb/s DMT signals over an 18-km GIRCF are experimentally demonstrated, respectively, to confirm the feasibility of our proposed OAM-MGM scheme.

description: Modern SoCs integrate multiple CPU cores and Hardware Accelerators (HWAs) that share the same main memory system, causing interference among memory requests from different agents. The result of this interference, if not controlled well, is missed deadlines for HWAs and low CPU performance. State-of-the-art mechanisms designed for CPU-GPU systems strive to meet a target frame rate for GPUs by prioritizing the GPU close to the time when it has to complete a frame. We observe two major problems when such an approach is adapted to a heterogeneous CPU-HWA system. First, HWAs miss deadlines because they are prioritized only when they are too close to their deadlines. Second, such an approach does not consider the diverse memory access characteristics of different applications running on CPUs and HWAs, leading to low performance for latency-sensitive CPU applications and deadline misses for some HWAs, including GPUs. In this paper, we propose a Simple QUality of service Aware memory Scheduler for Heterogeneous systems (SQUASH), that overcomes these problems using three key ideas, with the goal of meeting HWAs’ deadlines while providing high CPU performance. First, SQUASH prioritizes a HWA when it is not on track to meet its deadline any time during a deadline period, instead of prioritizing it only when close to a deadline. Second, SQUASH prioritizes HWAs over memory-intensive CPU applications based on the observation that memory-intensive applications’ performance is not sensitive to memory latency. Third, SQUASH treats short-deadline HWAs differently as they are more likely to miss their deadlines and schedules their requests based on worst-case memory access time estimates. Extensive evaluations across a wide variety of different workloads and systems show that SQUASH achieves significantly better CPU performance than the best previous scheduler while always meeting the deadlines for all HWAs, including GPUs, thereby largely improving frame rates.
