Open danrosen25 opened this issue 3 years ago • 3 comments

TYPE: fix

KEYWORDS: NUOPC, GNU

SOURCE: Daniel Rosen ([email protected]) - NCAR/ESMF

DESCRIPTION OF CHANGES: Fix GNU compiling issues

ISSUE: none

TESTS CONDUCTED: Built and run on Cheyenne using gnu/9.1.0 and mpt/2.25. Note that HDF4-4.2.11 (outdated) was having issues building with gnu/10.1.0, which is the default on Cheyenne.

This PR is on hold. I'm seeing bad values in the results using GNU 9.1.0. I've also had some trouble with variable initialization that may be due to compiler optimization. I may try to run with reduced optimization or switch the compiler when I have more time.

Hi @danrosen25, had a PR meeting and was just wondering if the status of this PR had changed at all? Is there a test case on Cheyenne that you could point us to?

I had tested this PR, but not with NUOCP coupling... which kinda seems like the import part ; )

Hi @scrasmussen, this is still on hold I haven't been able to go through the debugging process to determine why the different compiler is producing different results. I'll have to run each component individually using Intel and GCC and see which component is different.
