I need to run the CASTEP code from batch file (Windows 10).

I use the RunCASTEP.bat -np 16 seed_name syntax. This works.

I have a PC with 32 fyzical, 64 logical procesors ...

After usinng RunCASTEP.bat -np 32 seed_name command, CASTEPS does not run correctly - looks like some zombie mode with no results and infinite hang in memory ...

With identical input the -np 16 works OK ....

I am sure this is not a memory issue (16 CPu need abut 16 GB, I have 126 GB).

Is this a known limit/bug ?
