Machine for LAMMPS | Information dissemination media for research and development TEGAKARI

A customer involved in research on building materials asked us for a PC that can use LAMMPS with Red Hat Enterprise Linux.
It is assumed that J-OCTA will be run on another PC, calculation conditions and data sets will be created, and parallel calculation will be performed with LAMMPS on this PC within the same network.

Based on your request, we proposed the following configuration.

CPU	Xeon Silver 4416+ (2.00GHz 20 cores) x2
memory	128GB REG ECC
storage	1TB M.2 SSD
video	NVIDIA T400 4GB (MiniDisplayPort x3)
network	on board (10GBase-T x2)
Housing + power supply	Tower type housing + 1000W
OS	Red Hat Enterprise Linux Workstation Standard 1Y

It is a configuration that selects a CPU that can secure a certain number of cores within the budget of 120 million yen.

In this configuration, GPGPU is not assumed due to budget considerations, so we have adopted an entry-class video card that is only intended for drawing. As for Red Hat Enterprise Linux, we have received confirmation from our customer that J-OCTA has been working on version 8, so we are using it as an OS.

The configuration of this case study is based on the conditions given by the customer.
Please feel free to contact us even if you are considering different conditions from what is posted.
