Dear Prof. Blaha,

Thanks for your clarification. Will you help me now how to locate the
"libmpi_usempif08.so.40"

I would like to know, Is there any relation to the mentioned error and
OMP_SWITCH.

Do you suggest that I must install wien2k by loading the cray-mpich module
instead of the intel module.?
