[petsc-users] about MPI

[Likun Tan]

Hello,

I try to run my code with MPI, but i got the message: 'mpiexec: command
not found'. I installed mpi and tested it successfully on examples with
'make all test'.

I also tried to specify the path for mpi with ./config/configure.py
--with-mpi-dir=/home/likunt/petsc-3.1-p8/externalpackages/mpich2-1.0.8,
but it shows 'unable to configure with given options'.

Any suggestions on this?

Thanks,
Likun
