TIMEEV test fails in VASP 6.6.0

To whom it may concern,
I have built VASP6.6.0 with gcc/13.2.0, openmpi/5.0.6, aocl/4.1.0, and hdf5/1.14.2 on an AMD EPYC 7713 64-Core Processor.
This run passes all tests in the testsuite except SiC_TIMEEV.
Note that the “errors” related to libxc and wannier90 are to be expected since neither libxc nor wannier90 was included in the build.
I noticed a known issue with TIMEEV and ISYM>O that would apply to this test. Is this the same issue or an error with my build?
I have attached my makefile.include, the log from the build, and the output from the testsuite.
Do you have any recommendations on how to resolve this issue?

Dear John,
I see that you have used 8 MPI ranks instead of 4. See the warning in the log file:
Code: Select all
Reference files have been generated with 4 MPI ranks.
Note that tests might fail if an other number of ranks is used!
Did you run the testsuite with 4 MPI ranks? Did the SiC_TIMEEV test pass?
Best regards,
Alexey

Alexy,
I have run the SiC_TIMEEV test with 4 MPI ranks, and it passed!
Thank you!

Glad to see that it solved the issue. I will investigate further why this test fails with 8 MPI ranks and see if we can make it more stable.
