spmm_coo_batched

cuSPARSE Generic APIs - Batched cusparseSpMM COO

Description

This sample demonstrates the usage of cusparseSpMM for performing batched sparse matrix - dense matrix multiplication, where the sparse matrix is represented in COO (Coordinate) storage format.

cusparseSpMM Documentation

C[1] = alpha * A[1] * B[1] + beta * C[1] C[2] = alpha * A[2] * B[2] + beta * C[2]

Building

• Command line

  nvcc -I<cuda_toolkit_path>/include spmm_coo_batched_example.c -o spmm_coo_batched_example -lcusparse

• Linux

  make

• Windows/Linux

  mkdir build
  cd build
  cmake ..
  make

  On Windows, instead of running the last build step, open the Visual Studio Solution that was created and build.
