NAME

HPL_jumpit - jump into the random sequence.

SYNOPSIS

#include "hpl.h"

void HPL_jumpit( int * MULT, int * IADD, int * IRANN, int * IRANM );

DESCRIPTION

HPL_jumpit jumps in the random sequence from the number X(n) encoded in IRANN to the number X(m) encoded in IRANM using the constants A and C encoded in MULT and IADD: X(m) = A * X(n) + C. The constants A and C obviously depend on m and n, see the function HPL_xjumpm in order to initialize them.

ARGUMENTS

MULT (local input) int *

On entry, MULT is an array of dimension 2, that contains the 16-lower and 15-higher bits of the constant A.

IADD (local input) int *

On entry, IADD is an array of dimension 2, that contains the 16-lower and 15-higher bits of the constant C.

IRANN (local input) int *

On entry, IRANN is an array of dimension 2, that contains the 16-lower and 15-higher bits of the encoding of X(n).

IRANM (local output) int *

On entry, IRANM is an array of dimension 2. On exit, this array contains respectively the 16-lower and 15-higher bits of the encoding of X(m).
