No, Chaco can do an arbitrary number.
Thanks,

For this particular case (one subdoanin), it may be easy to fix in petsc.
We could create a partitioning index filled with zeros.
Fande,

IIRC, Chaco does not produce an arbitrary number of subdomains. The number
needs to be like 2^n.
ParMETIS and PTScotch are much better, and they are production-level code.
If there is no particular reason, I would like to suggest staying with
ParMETIS and PTScotch.
Thanks,

Dear Barry,
Thank you for answering. I am sending a sample code and a binary file.
Thanks!

Could be a bug in Chaco or its call from PETSc for the special case of one
process. Could you send a sample code that demonstrates the problem?

Hi all,
I am trying to try something. I am using the same MatPartitioning codes for
both CHACO and ParMETIS:
ierr = MatConvert(SymmA,MATMPIADJ,MAT_INITIAL_MATRIX,&AL);CHKERRQ(ierr);
ierr = MatPartitioningCreate(MPI_COMM_WORLD,&part);CHKERRQ(ierr);
ierr = MatPartitioningSetAdjacency(part,AL);C
