[petsc-users] metis for dev version of petsc

[Ravi Kannan]

Hi all,

 

For the last few years, we were using metis function (for partitioning) as
follows: 

 
METIS_PartGraphKway(&nCells,&ia[0],&ja[0],&vwgt[0],&adjwgt[0],&wgtflag,&numf
lag,&nParts,options,&edgecut,&part[0]);

 

Recently, we started using the development version for some testing. 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?

 

Thanks,

Ravi.
