Full Discussion: True random numbers in Sol10

I'll be more specific.

Say I want to get a random number in fortran through the following statement 'call random_number(arg)'. The question is: how can I make sure that this call does not return a pseudo-random number but instead a random number generated by the HARDWARE "true" random number generator of the SPARC T2 chip?

I need this for simulations so I do require true random numbers.

Thanks

NAME
slarnv.f - SYNOPSIS
Functions/Subroutines subroutine slarnv (IDIST, ISEED, N, X) SLARNV returns a vector of random numbers from a uniform or normal distribution. Function/Subroutine Documentation subroutine slarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, real, dimension( * )X) SLARNV returns a vector of random numbers from a uniform or normal distribution. Purpose: SLARNV returns a vector of n random real numbers from a uniform or normal distribution. Parameters: IDIST IDIST is INTEGER Specifies the distribution of the random numbers: = 1: uniform (0,1) = 2: uniform (-1,1) = 3: normal (0,1) ISEED ISEED is INTEGER array, dimension (4) On entry, the seed of the random number generator; the array elements must be between 0 and 4095, and ISEED(4) must be odd. On exit, the seed is updated. N N is INTEGER The number of random numbers to be generated. X X is REAL array, dimension (N) The generated random numbers. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Date: September 2012 Further Details: This routine calls the auxiliary routine SLARUV to generate random real numbers from a uniform (0,1) distribution, in batches of up to 128 using vectorisable code. The Box-Muller method is used to transform numbers from a uniform to a normal distribution. Definition at line 98 of file slarnv.f.
