PLASMA tiled Cholesky factorization

Postby iota » Wed Jul 14, 2010 3:50 am

Hi,
In PLASMA the tile Cholesky algorithm is implemented by calling following kernels.

DSYRK
DPOTRF
DGEMM
DTRSM

Could I know the measure of total number of operations (flop count )for each of the above block operations?

Thank you very much.

Hi,

you can find flop count for almost all LAPACK operations in the LAWN 41 : http://www.netlib.org/lapack/lawns/lawn41.ps
