R-ScaLAPACK

Description

The R-ScaLAPACK package provides a backwards compatible interface to the ScaLACPACK version of several R functions which presently use LIN/LAPACK.

Details

The ScaLAPACK library performs many common linear algebra functions in parallel on distributed or shared memory architectures. It is based on the LAPACK library. The R-ScaLAPACK package provides an interface to the most common ScaLAPACK functions available in an R compatible form.

All of the functions are named "sla.*", and the take the same (or as similar as possible) parameters as the normal R version. All functions have the additional parameters of the process grid and block size. A default process grid may be placed in the variable ".RscalaGrid", which will be used by the sla.* functions when no grid is given in their parameters.
