Hi,

I have the following problem with compiling vasp.6.2.1 with intel oneAPI. My machine is AMD Ryzen Threadripper 3990X 64-core

I compile it with oneAPI (2021.4) following this procedure:

Copy arch/makefile.include_intel to makefile.include
change -xHOST to -march=core-avx2
make

compiles fine Then when I run the testsuite, many tests pass normally, but it gets stuck to HEG_333_LW. See the attached screenshot: large_slab.tar.gz

.
You can see at the htop window that the process uses a lot of kernel cpu time (see red bars). See

When I run my own test, in a small bulk system it runs fine, but in a big slab system it runs into exactly the same problem. Here is the screenshot:

I attach input files as well:

large_slab.tar.gz

Any help would be very appreciated.

Best regards,
Andreas Kyritsakis

Hi,

This issued could be related to the fabrics control in the Intel MPI library.
Can you try setting the argument I_MPI_FABRICS=shm in your mpirun command?

Code: Select all

mpirun -np 64 -genv I_MPI_FABRICS=shm vasp_std

Hi,

I tested it and it works fine with this command. Thank you very much Alexey.

Best,
