Hello all,
I'm new to ParMetis. I am trying to use my laptop as a single processor developement machine for a parallel code already use parmetis. I have installed mpich and have compiled Parmetis with icc. ptest gets to :
Testing ParMETIS_V3_AdaptiveRepart with options[1-3] = {7 1 1}, ipc2redist: 1000.000, Ncon: 1, Nparts: 2
and then gives: 0 - MPI_RECV : Invalid rank 1
[0] Aborting program !
[0] Aborting program!
p0_11069: p4_error: : 8262
mtest won't even work.
q1)Has anyone tried to get ParMetis working on a single processor machine?
q2)are the errors above from an issue with single proc, or a compiling issue?

ParMetis needs to run on at least two processors (i.e., mpirun -np 2).

thank you george,
I'm working with an MHD code that uses parmetis for the domain decomposition...do you think that Metis could be used instead (with no true domain decomp., ofcourse)? Are all the commands the same in parmetis and metis?
