[Beowulf] MPI build with different compilers

[amjad ali]

Hi,
Please reply me about followings:


1) Is there any significant performance difference between OpenMPI
built with GNU compilers and the one built with Intel compilers?


2) Once we have built mpi on our system and then we remove the C/C++
and Fortran compilers from the system. Will the mpicc and mpif90 still
work properly? or the mpi bulit always needs installed base compilers?


Regards,
AA.
