The vasp (6.5.1) build with compiler/intel/20 openmpi/4.1 intel-mkl/20
keeps on crashing with a segmentation fault. (see error message below).
The build is successful with any of the makefile.include
(makefile.include.intel, makefile.include.intel_omp,
makefile.include.intel_ompi_mkl_omp) and the error is the same for each
case.

What puzzles me is that the build with the same include file works just
fine for 6.4.3. I would appreciate any help/direction to solve the issue.

I found a similar issue reported earlier, but it was for a different Intel
system and is not applicable to me.

Thank you in advance for helping me.

It turns out the issue was caused by using the Intel MPI BLACS library instead of the OpenMPI one. Thank you everyone for reading..

Dear tpaudel,

Great you were able to solve your issue on your own.

All the Best Jonathan
