Re: stack, heap, and segmentation faults on large simulation

Thank you for the info. We set -fp-model-precise option for standard IEEE floating point operations in any application. Otherwise, we will not able to check parallel partition bugs. Without this option ifort will give different results with the same executable and partition. It becomes completely i...

Apparently our cluster did have a restricted memory problem (restricted stack size), which the new settings have overcome. Not a ...
