HPL_jumpit(3) HPL Library Functions HPL_jumpit(3)NAMEHPL_jumpit - jump into the random sequence.
SYNOPSIS
#include "hpl.h"
void HPL_jumpit( int * MULT, int * IADD, int * IRANN, int * IRANM );
DESCRIPTIONHPL_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).
