Utilize Xterm access to servers through network. The engineering run occurred in 1991. Event rates are moderate at about 0.3 Hz with event sizes of about 250 kB. Our issues have been compute cycles, primarily for MC simulation and user analysis, access to the data on disk and in the tape silo, and the desktop. The online acquisition and monitoring are handled in VMS on two machines, a VAX 8800 and a 6420. Data is written directly into the tape silo from the acquisition machine.
Interactive analysis tends to use up all available cycles when there is data to be analyzed.
Similar loads local to compute engines are expected for user interactive analysis. We expect to need on the order of 250 GB of disk to handle our data and MC DST's, while about 150 GB will be needed for various needs, like tape staging, MC and data processing buffers, and user disks. We estimate requiring about 10,000 slots for 0.8 GB cartridges in the tape silo. We do not envisage the need to go to the next tape technology. Remote institutes are expected to acquire local computing resources and to transport copies of the DST's for home consumption.
