compiling with openmpi 2018
 

getting an error on csr.c in metis routines. it's just a warning, but my parallel config is not running parallel, so I'm wondering if this is the problem.

CC GKlib/libmetis_a-csr.o
GKlib/csr.c(796): warning #3180: unrecognized OpenMP #pragma
#pragma omp parallel private(i, j, ncand, rsum, tsum, cand)
^

GKlib/csr.c(800): warning #3180: unrecognized OpenMP #pragma
#pragma omp for schedule(static)

I got rid of the warning with --with-metis-cppflags="-fopenmp"
Now to see if it will run in parallel

It won't run the partitioning step now. It gets to "Read Grid File Information", lists the number of points, and then dies, saying "could not launch executable"

I'm using a pbs scheduler, and have all my path and environment set up properly i'm pretty sure.

What version of openmpi are you using specifically (x.y.z)?

How are you compiling the code?

Before using a scheduler, have you tried running on a local machine?

openmpi_3.0.1_intel_2018
intel_2018.2.199

Haven't tried serial since it's really of no use to me and I can't run interactive on our main cluster.

Right now, it seems to be a path issue to whatever is called to do the grid partitioning. But when I had that step working, it would load one cpu up with the entire parmetis job and eventually die due to maxxing out the memory.

I went with mpt instead of openmpi and it is working!
