Expand the set of implemented MPI operations

[sappyb]

Hi,

I am trying to use codes for my project. I am trying to run big fft traces, while doing so I encountered a problem called MPI sim layer does not have the operation, the mpi operation that is not implemented in comm_create and comm_dup. Is there a way around this problem. A large number of mpi applications uses those mpi operation, as such is there a way around for this problem.

Expanding the set of MPI operations simulated by CODES isn't currently a priority but it is under consideration for the future. Changing this issue to a feature request and adjusting the issue title accordingly.

There have been efforts to expand this through things like CODES-CORTEX but that also doesn't support the operations you're looking for.
