Name
HPL_setran Manage the random number generator.
Synopsis
#include "hpl.h"
void
HPL_setran(
const int
OPTION,
int *
IRAN
);
Description
HPL_setran
initializes  the random generator with the encoding of the
first number X(0) in the sequence,  and the constants a and c used to
compute the next element in the sequence: X(n+1) = a*X(n) + c.  X(0),
a and c are stored in the static variables  irand, ias and ics.  When
OPTION is 0 (resp. 1 and 2),  irand  (resp. ia and ic)  is set to the
values of the input array IRAN.  When OPTION is 3, IRAN is set to the
current value of irand, and irand is then incremented.
Arguments
OPTION  (local input)                 const int
        On entry, OPTION  is an integer that specifies the operations
        to be performed on the random generator as specified above.
IRAN    (local input/output)          int *
        On entry,  IRAN is an array of dimension 2, that contains the
        16-lower and 15-higher bits of a random number.
