I'm trying to run a simple estructure in Castep (MS 21.1) with a fresh Centos 8 installation with Processor: Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz but i get this error:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

I did this too:

export OMP_STACKSIZE=256M
ulimit -s unlimited

I have tested on some Xeon E5xx processors and works with fresh Centos 8 installation.

I have tested on Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz but with Centos 7 and it works, Is it compatibility problem with the processor Silver and Centos 8?

I'd appreciate your help

SOLUTION:

The problem is mpiexec, i got MPI older version (Version 5.1.2 Build 20151015) and i just do de follow:

- Copy mpiexec (symbolic link to mpiexec.hydra), mpiexec.hydra and mpdroot in /opt/BIOVIA/MaterialsStudio21.1/bin

Maybe is MPI problem with Intel Silver processors and Centos 8, maybe we can report this.
