Sparse Matrix Storage Formats for Inspector-executor Sparse BLAS Routines

Inspector-executor Sparse BLAS routines support four conventional sparse matrix storage formats:

  • compressed sparse row format (CSR) plus variations
  • compressed sparse column format (CSC) plus variations
  • coordinate format (COO)
  • block sparse row format (BSR) plus variations

Computational routines operate on a matrix handle that stores a matrix in CSR or BSR formats. Other formats should be converted to CSR or BSR format before calling any computational routines. For more information see Sparse Matrix Storage Formats.
