Exchange rate is calculated with $1 = ¥114.

Intellectual Property Rights are reserved completely by theusers and are not required to be shared with Tokyo Tech.
“NodeH” is the unit for pricing. 1 NodeH is equivalent to 1 nodefor 1 hour.
For example, if you pay $96, you can use 100 nodes for
1 hour, or 1 node for 100 hours.
Each node has 2 Intel Xeon processors (28 cores) and 4NVIDIA Tesla P100 GPUs, with 256GB Memory.
“Publicity: Disclosure” requires company name, division, purpose to use and the report of result to be published.
“Publicity: Nondisclosure” only requires company name to bepublished.

How to Use TSUBAME?

Simulation of phase separated structures of polymeric materials with fillers
Takashi Honda (Research Association of High-Throughput Design and Development for Advanced Functional Materials (ADMAT))

SOBA (Soft Blend Analyzer) is developed to calculate the phase separation structure of particle filler and polymer mixing system and use MPI + GPU computers. The SCF theory of thepolymeric materials is introduced, and the particle filler is treated as DIP (Diffuse InterfaceParticle), which is a solvent whose shape is fixed in a spherical shape. To avoid local minimum structure, we introduced several methods of moving the filler in the SCF calculation.
Keywords:SCF theory, polymer composite, particle filler, diffuse interface particle, phase separatio(a)(b)(c)Figure 1. Phase separated structure of DIPs in an A/B polymer blend
System size is 323, χPP=106, two-dimensional system and periodic boundary conditions were introduced.
(a) initial structure, (b) after 50 step without the shape of DIPs, (c) after 100 step with the shape of DIPs.

HPCI Confederation
High Performance Computing Infrastructure- National grid infrastructure for HPC research
Resources- 15 supercomputers in Japan, including TSUBAME3.0- 90PB global shared storage to share data
Services- One-stop sign up to all resources- Single sign on to all resources using Shibboleth & GSI
Status- 9 projects use TSUBAME3.0 for the HPCI project on FY2021

Figure 2. Phase separated structure of DIPs in an A/B polymer blend
System size 1283, mesh size 2563, χPP=10⁶, periodic boundary conditions were introduced. The number of DIPs is 782 and the volume
fraction of the DIPs is 0.1. χAB=χAP=0.4.
