HPL_indxl2g(3) HPL Library Functions HPL_indxl2g(3) NAME HPL_indxl2g - Map a index-process pair into a global index. SYNOPSIS #include "hpl.h" int HPL_indxl2g( const int IL, const int INB, const int NB, const int PROC, const int SRCPROC, const int NPROCS ); 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.
