Sparse Matrix storage format

Postby pgya » Sun May 23, 2010 10:12 am

Hello,

I would like to use PLASMA in a project involving huge sparse matrices. (LU, Cholesky)

Is it possible to use a storage format like CCS?

Thank you!

No.
PLASMA is for dense matrices only.

If you use PLASMA with sparse matrix, you will have an important memory extra-storage. You should try projects like MUMPS, PaSTiX or SuperLU.
