The error message is generated based on the macro MPICH_NUMVERSION contained in the mpi.h file.<br>
<br>
Apparently MVAPICH also provides this macro, hence PETSc has no way to know that it is not MPICH.<br>
<br>
If you can locate in the MVAPICH mpi.h include files macros related explicitly to MVAPICH then we could possibly use that macro to provide a more specific error message.<br></blockquote><div><br><br></div><div>There is also a macro: MVAPICH2_NUMVERSION in mpi.h.
