LAPACK/ScaLAPACK Development

Hi all,

Could someone tell me if there are any parallel implementations of a sparse matrix-vector multiply routine (using CSR representation) within the ScaLAPACK library, when both vectors and matrices are distributed . If not, I would be grateful if anyone could direct me to any external routines they are aware of that can perform this task.

Thanks in advance,

Tim.

Hi,
there are no sparse operations in ScaLAPACK. Anyway there a number of packages for that:

PETSc
PSBLAS
TRILINOS
AZTEC
etc

You can find a list of linear algebra packages (including those for sparse operations) here:

Alfredo,

Thanks for that info. I am sure there is something there that can help me.

Best Wishes.
