random - Seeding QUASI_SCRAMBLED_SOBOL64 in CURAND -


how can seed curand_rng_quasi_scrambled_sobol64 generator? because gives me same numbers every time run , can't use curandsetpseudorandomgeneratorseed curand_rng_quasi_scrambled_sobol64 generate 64 bit random integers curandgeneratelonglong.

how seed generator in following code?

size_t n = 10; curandgenerator_t gen; unsigned long long *devdata, *hostdata;  hostdata = (unsigned long long *)calloc(n, sizeof(unsigned long long));  cudamalloc(&devdata, n*sizeof(unsigned long long)); curandcreategenerator(&gen, curandrngtype_t::curand_rng_quasi_scrambled_sobol64);  (size_t j = 0; j < 3; j++) {     curandgeneratelonglong(gen, devdata, n);     cudamemcpy(hostdata, devdata, n * sizeof(unsigned long long), cudamemcpydevicetohost);     (size_t = 0; < 3; i++) {         printf("%llx\n", hostdata[i]);     }     printf("\n\n"); }  curanddestroygenerator(gen); cudafree(devdata); free(hostdata); 

as per docuementation, quasi random generators, sobol generator using, don't use seed. use offset , dimension vector initialise generator.

so initialisation sequence in code should like

curandcreategenerator(&gen, curandrngtype_t::curand_rng_quasi_scrambled_sobol64); curandsetgeneratoroffset (gen, std::time(0)); curandsetquasirandomgeneratordimensions(gen, 10);
