[Trilinos-Users] [EXTERNAL] Belos and AztecOO Conversion

[Klinvex, Alicia Marie]

Hello Shilei,

It's not clear to me what you're trying to do.  Are you trying to find the equivalent solvers in Belos? If so, you want pseudo-block CG in the first case.  I don't believe we have an implementation of CGS in Belos, unfortunately.

Please let us know if your question has been interpreted incorrectly, or if you need any additional information.

Best wishes,
Alicia

Dear developers / Users,

I am trying to modify an AztecOO solver using AZ_cg and AZ_cgs as Specifications.
I am not sure what is the direct solver manager for those two conjugate gradient methods.

I believe this table contains all the solvermanager type for Belos
