[petsc-users] Building PETSc with Intel mpi

[Qin Lu]

The Intel mpi's wrappers to Intel compilers are mpiicc and mpiifort (not mpicc and mpif90), can PETSc's configure automatically pick them? Or I have to specify them explicitly (--with-cc=mpiicc --with-fc=mpiifort --with-mpi-compilers=0)?

Thanks,
Qin

Does this mpi not come with mpicc/mpif90 wrappers? If they do - its best to use them.

If not - its best to look at the docs for this compiler - and specify it with the appropriate

--with-mpi-include --with-mpi-lib options, [instead of the above]

If I have to specify the lib names (using --with-mpi-lib?), which libs should I specify? I saw a lot of libs under the directory, such as libmpi.a, libmpi_ipl64.a, libmpi_mt.a, etc.
