GPU A100 cannot be seen in ansys v241 mechanical and fluent:<\/p>\n

We are trying to run Ansys mechanical and fluent of v241 on GPU server.<\/p>\n

GPU server consists of two AMD EPYC 7452 CPUs and four Nvidia A100 GPUs, and its OS is ubuntu 20.04.6 LTS (Focal Fossa).<\/p>\n

Nvidia driver is v520.61.05 and GPUs are seen by driver command such as nvidia-smi. (CUDA is also installed and it is v11.8)<\/p>\n

Ansys v241 is successfully installed, however, any calculations are not performed on GPUs.<\/p>\n

We had tried GPU allocation with each module, i.g., on the mechanical, proceeding Solve > Solve Process Settings > Advanced Properties and setting GPU resources. However, GPUs do not work.<\/p>\n

Is there any setting we need for utilization of those GPUs?<\/p>\n

 <\/p>\n

This would be very basic question, but we will be very happy if anybody reacts to this.<\/p>\n

Thank you.<\/p>\n","protected":false},"template":"","class_list":["post-357018","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
