Machine for Gaussian (October 2022 version)

PC-8617AWe received a request from a customer viewing the machine for using the Gaussian 16W 32bit multiprocessor version.
It is a request to introduce a configuration that assumes the use of Gaussian and Gaussview with a budget of about 100 million yen.
The OS is scheduled to be Windows, and we have received the following as specific specifications.

CPU: about 30 cores
Memory: 128GB
GPU: NVIDIA T1000 8GB

However, in the case of Gaussian 16W 32bit for Windows, available hardware resources are severely limited.

■G16W System Requirements *Jump to Gaussian's official website

the 32-bit version of Gaussian 16W is limited to accessing at most 2 GB of RAM and 16 GB of disk regardless of how much memory is available on the system.
The 32-bit multiprocessor version of G16W is limited to 4 processors (or cores).

As mentioned above, you can use up to 4 cores and up to 2GB of memory.
This is due to the specifications of the 32-bit program and cannot be avoided.
Therefore, if the use of the 32-bit version is a prerequisite, even if you introduce a two-socket and large-capacity memory configuration such as the case study No. PC-8617A, we will not be able to take full advantage of the performance. I asked them to reconsider the policy.

As a result, we received a message that Gaussian 64bit version will be introduced, and we also considered the configuration of the machine side according to the 64bit version.
The CPU has a 2 CPU configuration of Xeon Scalable, realizing a total of 32 cores.
Considering the balance between the budget and the overall specs, we believe that a CPU with a configuration around 32 cores would be optimal.
