Rank sort Assignment Answers

Question:

Implement the rank sort in a parallel way using CUDA.

Rank sort Answer and Explanation

    int tid = blockIdx.x * blockDim.x + threadIdx.x;

    if (tid < n) {

            }

        }

    int tid = blockIdx.x * blockDim.x + threadIdx.x;

    if (tid < n) {

    int *d_input, *d_ranks, *d_output;

    int size = n * sizeof(int);

    // Copy input data to the device

    cudaMemcpy(d_input, h_input, size, cudaMemcpyHostToDevice);

    computeRanks<<<gridSize, blockSize>>>(d_input, d_ranks, n);

    cudaDeviceSynchronize();

    cudaMemcpy(h_input, d_output, size, cudaMemcpyDeviceToHost);

    // Free device memory

int main() {

    int h_input[] = {3, 6, 1, 8, 4, 5};

    }

    std::cout << std::endl;

    }

    std::cout << std::endl;
