HPF Interface for ScaLAPACK

• Interface provided for a subset of routines

• Linear solvers (general, pos. def., least squares) & matrix multiply

• Given these declarations:

USE HPF_LAPACK

REAL, DIMENSION(1000,1000) :: A, B, C

!HPF$ DISTRIBUTE (CYCLIC(64), CYCLIC(64)) :: A, B, C

• Calls could be made as simple as:

CALL LA_GESV(A, B)

CALL LA_POSV(A, B)

CALL LA_GELS(A, B)

CALL LA_GEMM(A, B, C)

(same as F90)
