plot_dmat: Visualizing the DMAT Data Structure

In RBigData/pbdDEMO: Programming with Big Data -- Demonstrations and Examples Using 'pbdR' Packages

Description

Plot a (small) global matrix as though it had been chopped up into pieces in the block-cyclic fashion.

Usage

plot_dmat(nrow, ncol, nprow, npcol, bldim, ..., labeling = "blacs",
  col = "rainbow")

Arguments

nrow, ncol	Number of global rows/columns of the matrix.
nprow, npcol	Number of processor rows/columns in the BLACS grid.
bldim	The blocking factor for the data distribution.
...	Additional arguments
labeling	Character argument; should be "blacs" or "mpi". This determines how the processor labeling should be, either in the 2-d BLACS way, or in the 1-d MPI way.
col	R plots color argument

Details

This function helps the user visualize 2-d block-cyclic distributed data.
