Programming with Big Data – Scalable Linear Algebra Packages

Description

pbdSLAP utilizes scalable linear algebra packages mainly including BLACS, PBLAS, and ScaLAPACK in double precision via pbdMPI based on ScaLAPACK version 2.0.2.

Details

This package requires pbdMPI and MPI system. The main purpose of pbdSLAP is to provide several scalable linear algebra packages containing double precision libraries for pbdDMAC or other useful packages.

SLAP Grid

Description

These functions initializes a grid of pbdSLAP, assigns the information to a global object, and free the grid.

Usage

  slap.init.grid(nprow, npcol = 1, ictxt = 0)
  slap.exit.grid(ictxt)
  slap.finalize(quit.mpi = FALSE)

Arguments

nprow

number of row processors.

npcol

number of column processors.

ictxt

the grid id

quit.mpi

if finalize MPI.
