A customer involved in research on drifting objects in the ocean asked us about a machine for ocean current simulation.
The customer's expected specifications are as follows.
・CPU: Xeon Gold 5320 (2.2GHz 22 cores) x2 or equivalent |
I have heard that the actual calculation will run a Fortran program using OpenMP, and the compiler will use Gnu Fortran.
Since the calculation program to be executed is similar to fluid calculation, the results of the Himeno Benchmark are used as a reference in machine selection.
Based on the conditions given by the customer, we proposed the following configuration.
【Main Specifications】
CPU | AMD Ryzen ThreadripperPRO 5975WX (3.60GHz 32 cores) |
memory | 128GB |
Storage 1 | 1TB SSD S-ATA |
Storage 2 | 8TB HDD S-ATA |
Video | Nvidia T400 |
network | on board (1GbE x1 10GBase-T x1) |
Housing + power supply | Tower type housing + 1000W |
OS | Microsoft Windows 11 Pro 64 bit |
The CPU is AMD Ryzen ThreadripperPRO 5320WX instead of Xeon Gold 5975.
■ Points ・Looking at trends in the Himeno Benchmark, CPUs with a high per-core capacity tend to rank higher than CPUs with a large number of cores. |
Based on information from the Himeno Benchmark, which is used as an index, I thought that it might be better to give priority to the speed per core when using OpenMP, and made a proposal.
However, depending on the actual processing content and usage, the way of thinking about CPU selection may differ, so it is not always correct to give priority to the speed per core.Please consider the configuration of this example as a proposal within the range of information that could be confirmed.
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.
