C++ (Cpp) curandGenerate Examples

Example #1

File: test_common.cpp Project: 105/caffe

TEST_F(CommonTest, TestRandSeedGPU) {
  SyncedMemory data_a(10 * sizeof(unsigned int));
  SyncedMemory data_b(10 * sizeof(unsigned int));
  Caffe::set_random_seed(1701);
  CURAND_CHECK(curandGenerate(Caffe::curand_generator(),
        static_cast<unsigned int*>(data_a.mutable_gpu_data()), 10));
  Caffe::set_random_seed(1701);
  CURAND_CHECK(curandGenerate(Caffe::curand_generator(),
        static_cast<unsigned int*>(data_b.mutable_gpu_data()), 10));
  for (int i = 0; i < 10; ++i) {
    EXPECT_EQ(((const unsigned int*)(data_a.cpu_data()))[i],
        ((const unsigned int*)(data_b.cpu_data()))[i]);
  }
}

Example #2

File: curand_dlibapi.cpp Project: 20337112/dlib

        void curand_generator::
        fill (
            cuda_data_ptr<unsigned int>& data
        )
        {
            if (data.size() == 0)
                return;

            CHECK_CURAND(curandGenerate((curandGenerator_t)handle, data, data.size()));
        }
