[Trilinos-Users] Solvers for sparse systems

[Heroux, Michael A]

Karol,

Trilinos provides many linear solver capabilities.  There is an overview page (a bit out-of-date, but still relevant) that you can find here:

http://trilinos.sandia.gov/CapabilityWebpages/LinearEigenCapabilities/overview.html

The easiest way to access linear solvers is by using the Stratimikos package, which provides an integrated interface accessing all linear solvers in Trilinos:

http://trilinos.sandia.gov/packages/docs/r10.8/packages/stratimikos/doc/html/index.html

The simplest example using Stratimikos is here:

If you have more information about the problem you are solving, we can give you more detailed guidance.

Best regards,

Mike

Hello.

I need to solve a linear, sparse system. Which solvers are available in whole Trilinos project? I've searched for it, but the only thing I found in Trilinos tutorial is (in Epetra section): "Support is provided
for common matrix operations, including scaling, norm, matrix-vector multiplication and
matrix-multivector multiplication". Could you help me where find a list of supported solving methods for sparse linear systems?

Regards

Karol Gruchany
