# HPL_jumpit man page

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).
