[Trilinos-Users] [EXTERNAL] Call HYPRE from trilinos?

[Klinvex, Alicia Marie]

Hello Wen Yan,

My apologies for the delay; I was out of town.

We do have a Tpetra-based Trilinos/hypre interface, but it lives in a separate repository: https://github.com/trilinos/xSDKTrilinos.  The instructions for installing and using this interface can be found in the doc/xSDK_manual directory.  Please let me know if anything is unclear.

Best wishes,
Alicia Klinvex

Subject: [EXTERNAL] [Trilinos-Users] Call HYPRE from trilinos?

Dear Trilinos users,

I was wondering whether it is possible to call a matrix factorization method in the package HYPRE from Trilinos. My current program works well on the Belos/Tpetra/Ifpack2 stack, and I need to call the 'Parasail' method from HYPRE for an explicitly constructed Tpetra_CrsMatrix.

If that is not possible without explicit memory copy between Tpetra_CrsMatrix and HYPRE matrix, is there a Factorized Sparse Matrix Approximate Inverse solver that I can use within Trilinos?

Thank you,
Wen Yan
