[petsc-dev] PETSc Error during VecScatterCreate after MUMPS solve

[Jaysaval, Piyoosh]

Thanks Matt. I don’t think so; I used the default. I will give it a try again with 64-bit indices.

Do I just need to use --with-64-bit-indices during the configuration?

Hello PETSc developers,

I am having some issues with using MUMPS solver after the solution phase from PETSc. I am solving a matrix equation with about 2.17 million DOFs and for 1764 RHSs. MUMPS successfully solves the system for all RHS; however, after the solve phase the distributed solution from MUMPS vector/matrix is scattered back to PETSc mpi vector (done within PETSc) and this is where I am getting the error.

FYI, when I use 1323 RHSs, there is no issue. Moreover, I had to use v3.18.6 (or lower) because of some compiling issue with v3.19+ and SuperLU_DIST on our cluster with older intel mpi.

Any help is greatly appreciated. Thanks.

Have you configured with 64-bit indices?

  Thanks,

Here’s is the error message I am getting:
