Porting a sphere optimization program from LAPACK to ScaLAPACK

Leopardi, Paul; Womersley, Robert

Description

The sphere optimization program sphopt was originally written as a sequential program using lapack, and was converted to use scalapack, primarily to overcome memory limitations. The conversion was relatively straightforward, using a small number of organizing principles which are widely applicable to the scalapack parallelization of serial code. The main innovation is the use of a compressed block cyclic storage scheme to store two symmetric matrices in little more than the storage needed for...[Show more]
