Hello,

I used to start Fluent at kinds of different CPUs successfully, but when I am starting the fluent on a 8358p cpu, it will stop at the last line of the message below:

What can I do to figure this problem out?

Thanks

Hello, Are you able to start with say 4 cores as a test. try using a different setting for interconnect, interface or MPI ?
