A customer consulted on a workstation suitable for a large number of calculation jobs using the molecular dynamics calculation program LAMMPS.
When assuming multiple calculation jobs by a large number of people, generally a machine with a large number of cores (number of threads) is suitable. In terms of market share, most software is often optimized for Intel CPUs, but this time it was mainly used on LAMMPS, which has many examples on AMD CPUs, so more We have proposed a configuration that uses AMD EPYC which can use the cores of the above (suggestion for AMD EPYC 64P with 7702 cores).
【Main Specifications】
| CPU | AMD EPYC 7702P (2.0GHz 64 cores / 128 threads) |
| memory | 128GB (16GBx8) ECC REG |
| storage | SSD 2TB |
| video | NVIDIA GeForce RTX 2080 |
| network | GigabitLAN x2 |
| Housing + power supply | Tower enclosure (193 x 424 x 525 mm) + 1200W Platinum |
| OS | 7 CentOS |
| Others | LAMMPS installation (for GPU), NVIDIA CUDA Toolkit |
