Hi Sean,
Works now : we had to set a few arguments to NULL.

This needs a more recent version of metis: METIS_SetDefaultOptions(&options[0]); METIS_PartGraphKway(&nCells, &ncon, &ia[0],&ja[0],&vwgt[0],&vsize[0],&adjwgt[0],&nParts,&tpwgts[0],&ubvec[0], &options[0],&edgecut,&part[0]); This has the same function name but with different argument list. We noticed that the latest version does not partition properly as before : we get just one cell in the 0th partition. Any inputs on this? What are you setting for options? i.e. are you trying to use the default parameters or do you have your own weights? To follow up on Sean's note, is there a reason that this partitioning problem does not fit into MatPartitioning? If not, we would be very interested in extending our interface to support it.
