HPL_indxg2p(3)		     HPL Library Functions		HPL_indxg2p(3)

NAME
       HPL_indxg2p - Map a global index	into a process coordinate.

SYNOPSIS
       #include	"hpl.h"

       int  HPL_indxg2p(  const	int IG,	const int INB, const int NB, const int
       SRCPROC,	const int NPROCS );

DESCRIPTION
       HPL_indxg2p computes the	process	coordinate  which posseses  the	 entry
       of a matrix specified by	a global index IG.

ARGUMENTS
       IG      (input)		       const int
	       On  entry,  IG specifies	the global index of the	matrix	entry.
	       IG 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.

       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.
