Hi,

I am moving a VASP 5.4.1 installation from an old cluster installation (CentOS 6 with Intel 16 toolchain) to a new installation (CentOS 8 with the newest Intel OneAPI HPC kit). I am using the same makefile.include file with a minor change to reflect the different location of MKL. But the code that used to run on the old cluster seg faults on the new cluster. Can you give me some pointers on how to debug this problem? I've attached the relevant environment variables, makefile.include file that was used to build VASP 5.4.1 on the new cluster, and the error message produced by the seg fault. Thanks.

That is a very old VASP version, so we are not really giving support for that anymore.

Hard to say what it could be with that little information, but most likely a problem in one of the parts of the toolchain. Especially if it worked on another cluster.

You could try -traceback (also -debug and -g) to see where it crashes.
