DESCRIPTION
HPL_indxl2g
computes the global index of a matrix entry pointed to
by the local index IL of the process indicated by PROC.
ARGUMENTS
IL (input) const int
 
On entry, IL specifies the local index of the matrix entry.
IL must be at least zero.

INB (input) const int
 
On entry, INB specifies the size of the first block of the
global matrix. INB must be at least one.

NB (input) const int
 
On entry, NB specifies the blocking factor used to partition
and distribute the matrix A. NB must be larger than one.

PROC (input) const int
 
On entry, PROC specifies the coordinate of the process whose
local array row or column is to be determined. PROC must be
at least zero and strictly less than NPROCS.

SRCPROC (input) const int
 
On entry, SRCPROC specifies the coordinate of the process
that possesses the first row or column of the matrix. SRCPROC
must be at least zero and strictly less than NPROCS.

NPROCS (input) const int
 
On entry, NPROCS specifies the total number of process rows
or columns over which the matrix is distributed. NPROCS must
be at least one.
