codes-workload-dump failure on mpi-io-test darshan log (Imported #68) #68

Closed nmcglo closed 5 years ago

Original Issue Author: Jonathan Jenkins Original Issue ID: 68 Original Issue URL: https://xgitlab.cels.anl.gov/codes/codes/issues/68

To reproduce, compile codes-base using the --with-darshan option and run make check.

There is a test script enabled in this case that will dump the workload from a 4-process mpi-io-test darshan log example that fails with the following assertion:

codes-workload-dump: ../src/workload/methods/codes-darshan-io-wrkld.c:637: generate_psx_coll_file_events: Assertion `extra_opens <= open_cycles' failed.

Jonathan Jenkins:

Added extra logic to handle the case where a shared file is opened independently at the MPI level -- did not consider that case when originally implementing the Darshan generator and this test case was triggering an assertion.

After the fix and running make check, the Darshan generator no longer crashes and accurately reproduces the workload from this IOR configuration.

See git commit: dc1f19dd053a54055e8a5644ef3b7154298654dd
