[MITgcm-support] ARCHER, cray, mpi and STDOUT

[GOLDBERG Daniel]

thanks dimitris!

no doubt this will give a performance hit (will test if i get a chance) but this will help with debugging.

all the best

Hi Dan, I think that one way to make sure that STD* files are flushed more regularly is via option

 debugMode=.TRUE.,

in runtime parameter file eedata.  I don’t know if there is a performance hit for that.  You should test.

Hi All

I wonder if i can ask a question of MITgcm users on ARCHER, who are using cray fortran compilers?

I am used to monitoring the STDOUT.* files to monitor the progress of my runs. I have recently begun using ARCHER, and until now was using intel compilers, and this worked just fine -- the STDOUT.* files update frequently.

But I am now using cray compilers (via the optfile tools/build_options/linux_ia64_cray_archer) and am finding that STDOUT.* are not updated until the batch is completed. Has anyone else had similar issues? Are there any settings which can be changed, or any other files which receive standard output streams and are updated more frequently?

Many thanks if anyone has an answer!!!!

Best
Dan
