First Single-threaded (ST) NVPL RAND Program

Putting it together, here is a simple example generating 10000 FP32 numbers with standard normal distribution using a NVPL RAND generator with a single thread.

/*
 * This program uses single-threaded NVPL RAND library to generate 10000 FP32 numbers with standard normal distribution
 */
#include <vector>
#include <iostream>
#include "nvpl_rand.h"

#define NVPL_RAND_CHECK(x)                                  \
    do {                                                    \
        if ((x) != NVPL_RAND_STATUS_SUCCESS) {              \
            printf("Error at %s:%d\n", __FILE__, __LINE__); \
            _Exit(EXIT_FAILURE);                            \
        }                                                   \
    } while (0)

int main(int argc, char* argv[]) {
    nvplRandGenerator_t gen;

    const size_t              n = 10000;
    std::vector<float> array(n);

    /* Create pseudo-random number generator */
    NVPL_RAND_CHECK(nvplRandCreateGenerator(&gen, NVPL_RAND_RNG_PSEUDO_PCG));

    /* Set seed */
    NVPL_RAND_CHECK(nvplRandSetPseudoRandomGeneratorSeed(gen, 1234ULL));

    /* Set Offset */
    NVPL_RAND_CHECK(nvplRandSetGeneratorOffset(gen, 10ULL));

    /* Generate n 32-bit random numbers  */
    NVPL_RAND_CHECK(nvplRandGenerateNormal(gen, array.data(), n, 0, 1));

    for (auto i = 0; i < 10; i++) {
        std::cout << " i " << i << " " << array[i] << std::endl;
    }
    /* Cleanup */
    nvplRandDestroyGenerator(gen);
}
