[mvapich-discuss] detecting MVAPICH in C

[Ibanez, Daniel Alejandro]

Hello,

I was wondering if it is possible, by some C preprocessor macro, to detect whether my code is being compiled against MVAPICH as opposed to OpenMPI or plain MPICH? I indend to enable/disable certain parts of the code depending on whether the MPI implementation I’m using is CUDA/GPU - aware or not. As such, detecting the MVAPICH version in the preprocessor would also be helpful.

Thank you,
Dan Ibanez
