I don't know at which version icc began to accept -m64 (by ignoring it?). If you have recent versions of ifort and icc, they do need to be the same release version. Many people prefer to build MPI for linux by using ifort and gcc/g++. Someone may have more insight on the HPC forum, if you give more detail, although MPICH isn't often covered there.
