Hello everyone,

Our company has bought a new server with 4x Xeon Gold 6154 CPUs (18 cores, 36 threads each CPU) for Ansys Fluent calculations.
We have enough HPC pack licenses for up to 128 cores calculations, but I cannot use all of the core on the new server. When I start Fluent 18.1 with parallel settings of 72 cores (intel MPI), Fluent detects only 36 cores, even though there are 72 physical cores available according to Task Manager (hyperthreading is OFF at BIOS). Operating system is Win Server 2012R2.
Does anybody know how to solve that kind of problem? Is there any additional settings for using more than 36 cores? I have never used more than 32 cores before buying this server.

Thank you in advance!
