[mvapich-discuss] ifort 11.0.069 mvapich-1.1 weird conflict

[Jonathan Perkins]

Noam:
It appears that you are having this problem when using mvapich compiled
with 10.1 and the mpi programs compiled with 11.0.  When both the library
and the program use 10.1 there is no problem.  Can you make sure that
both the MPI library and your application are compiled with the same
compiler?  This should not lead to any problems.
