[petsc-users] a direct solver with support for 64-bit integers

[Hari Krishna Kodali]

Hi all,

I am looking for a parallel direct solver (as my problem is ill 
conditioned and the petsc provided
preconditioners don't help !) that can use 64 bit integers (due to large 
problem size).

I tried SUPERLU_DIST and MUMPS and both don't support 64-bit integer 
indices.
As my problem is not symmetric, i can't use one of the symmetric solvers.

Thanks,
