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.
