WebApr 27, 2012 · To give you an idea of how the pieces fit together, the following is a simple program which reads in a binary file containing a matrix (first the size of the square matrix N and then the N^2 elements) and then calculates the eigenvalues and vectors using scalapack's (new) pssyevr routine. It combines the MPI-IO, darray, and scalapack stuff.
Webmatrix multiplication routine PDGEMM of ScaLAPACK. PDGEMM is part of PBLAS which is the parallel implementation of BLAS (Basic Linear Algebra Subprograms) for distributed memory machines. It can be used as a building block in a parallel version of Strassen’s algorithm [4]aswellasinmanyad-vanced algorithms from scientific computing. WebScaLAPACK pdgemm. For rectangular matrices (m=4000 n=4000 k=1000) on the Linux cluster with Myrinet, SRUMMA outperformed ScaLAPACK pdgemm by 48.8%. In all cases, the same serial matrix multiplication was used. The paper is organized as follows. The next section describes the SRUMMA algorithm, its efficiency model, and implementation.
WebAug 11, 2024 · The main tool that PBSDC uses is a parallel structured matrix multiplication algorithm (PSMMA), which can be much faster than the general dense matrix multiplication ScaLAPACK routine PDGEMM. Numerous experiments have been performed on Tianhe-2 supercomputer to compare PBSDC with PBDC and ELPA.
