I had a complaint from a user that his MPI code would hang. We have a new cluster, so we are still in the test phase. I downloaded the latest version of HDF5 and built it, but the tests fail. I am using Intel’s Oneapi compilers.
===Parallel tests in testpar begin Mon Aug 8 14:35:35 PDT 2022===
**** Hint ****
Parallel test files reside in the current directory by default.
Set HDF5_PARAPREFIX to use another directory. e.g.,
HDF5_PARAPREFIX=/PFS/user/me
export HDF5_PARAPREFIX
make check
**** end of Hint ****
make[4]: Entering directory ‘/users/ramos/hdf5-1.12.2/testpar’
Testing: t_mpi
Test log for t_mpi
*** Hint ***
You can use environment variable HDF5_PARAPREFIX to run parallel test files in a
different directory or to add file type prefix. e.g.,
HDF5_PARAPREFIX=pfs:/PFS/user/me
export HDF5_PARAPREFIX
