Build with the Intel Classic Compilers 2021.6.0 and openmpi/4.1.5 fails ptest.

[Wei-Keng Liao]

Hi, John

I assume Improv is a cross-compiling environment.
On such an environment, the executables are supposed to run
on the compute nodes, instead of login nodes.

Can you try running "make ptest" in the interactive mode of qsub?
Also, set the output file folder to a folder on the scratch GPFS file
system. This can be done by setting TESTOUTDIR, for example,
"make ptest TESTOUTDIR=/lcrc/your/project/folder"

The error message "Bad file descriptor" hints this problem probably come
from MPI-IO. OpenMPI 4.1.5 is quite old. Maybe try a newer one? The latest
release of OpenMPI is 5.0.7.

To Whom It May Concern:

I have built pnetcdf 1.14.0 with the Intel Classic Compilers 2021.6.0 and openmpi/4.1.5 onArgonne's Improv Cluster<https://urldefense.com/v3/__https://www.lcrc.anl.gov/systems/improv__;!!Dq0X2DkFhyF93HkjWTBQKhk!WW8IV_sSJhTG9Qe03oym_xgfIyBYjyvS2Eo3PUDfjAXNlz3TvugBYYapVfzoLiqtbdYlCSiGMJlveYIgq1l_$ >.  It is a cluster of 825 nodes with two AMD EPYC 7713 64C 2GHz processors with an Infiniband HDR200 interconnect.

This build passes the serial tests but fails the parallel test invoked with the command "make ptests"

The third test in examples/C fails with the following error.

Error mmapping the file: Bad file descriptor

I have attached a config.log, output, and error.log from the failed test.

Any help in resolving this issue would be greatly appreciated.
