A customer involved in research in the field of brain science asked us for a machine for analyzing videos acquired by functional magnetic resonance imaging (fMRI).
Your requirements are as follows.
|
・Image analysis using MATLAB, Python, Fiji, etc. is assumed. |
Based on the information you provided, we proposed the following configuration.
【Main Specifications】
| CPU | Xeon Gold 6326 (2.90GHz 16 cores) x2 |
| memory | 512GB REG ECC |
| Storage 1 | 1TB M.2 SSD |
| Storage 2 | 7.68TB SSD U.2 |
| Video | Nvidia T1000 |
| network | On Board (1000Base-T X2) |
| Housing + power supply | Tower type housing + 850W |
| OS | Microsoft Windows 10 Pro 64 bit |
Considering CPU performance and memory capacity, it has a 3-CPU configuration with 2rd generation Xeon Scalable.
Considering the balance with the OS, we chose a CPU with 32 cores and 64 threads.
When Windows 10 recognizes more than 64 logical cores (threads), it creates a group of logical cores called a processor group.As a general rule, applications that are not explicitly designed to cross processor groups cannot parallelize across processor groups, and MATLAB is subject to this limitation.Therefore, even if more than 64 logical cores are installed, there will be situations where they cannot be fully utilized.

As a countermeasure to this situation, there is a method of disabling Hyperthreading and using only physical cores, and a method of changing the OS to Windows 11.
In Windows 11, the mechanism of processor groups has changed, and applications can access all logical cores regardless of the number of logical cores installed.
If there is no problem in terms of operation method, etc., please consider it as an option.
