Memory debugging

[fritzt]

Dear all,

I am reaching out to see if anyone has experience with running CIME with a memory debugger on Cheyenne.

I have been in charge of the coupling between CESM and GEOS-Chem, and I believe that I am running into some stack corruption, which surprisingly disappears when DEBUG is turned on.

I have been able to run ARM DDT on Cheyenne following a previous Github issue, but I have been unsuccessful with memory debugging. I have tried to statically link CIME with dmalloc libraries as described in the ARM Forge User Guide. Unfortunately, I haven't been able to get it to work, and I am wondering if anyone is able to run CIME with a memory debugger on Cheyenne.

Any hints on how to move forward would be much appreciated!

Thank you in advance!

Regards,
Thibaud

I have tried in the past, but haven't in a long time. If you are looking for a memory leak we often use the
memusage routines in the gptl library. gptlprint_memusage, gptlget_memusage.
