INDXGLOB

Coordinate of the process whose local info is to be determined.

IPROC

The coordinate of the process that possesses the first row/column of the distributed matrix. That's always 0 pbdDMAT.

ISRCPROC

Total number of processors over which matrix is distributed.

NPROCS

INDXLOC

Get the local index given global information.

An interface to and extensions for the 'PBLAS' and 'ScaLAPACK'
numerical libraries.  This enables R to utilize distributed linear algebra
for codes written in the 'SPMD' fashion.  This interface is deliberately
low-level and mimics the style of the native libraries it wraps.  For a much
higher level way of managing distributed matrices, see the 'pbdDMAT'
package.
