[MITgcm-support] Question about parallel run

[Ali Nazemian]

Thanks a lot.
So i should have a different source code per each run configuration and use
it for example with SGE as a job scheduler?
Is it in developer road map to make MITgcm more portable? i mean change
parallel configuration to runtime instead of compile time?
Regards.
