[MITgcm-support] Running on Discover

[Ariane Verdy]

Hi Dimitris,

Hong offered the solution (thank you!!) 
In case someone else runs into an error like this:

Caught signal 11 (Segmentation fault: address not mapped to object at address 0x7ffdc6995cd8)

Just add this line to the slurm script:

limit stacksize unlimited (for csh) 
or
ulimit -s unlimited (for bash)
