• New Features
    • Added new Generic APIs for Axpby (cusparseAxpby), Scatter (cusparseScatter), Gather (cusparseGather), Givens rotation (cusparseRot). __nv_bfloat16/ __nv_bfloat162 data types and 64-bit indices are also supported.

    • This release adds the following features for cusparseSpMM:

      • Support for row-major layout for cusparseSpMM for both CSR and COO format
      • Support for 64-bit indices
      • Support for __nv_bfloat16 and __nv_bfloat162 data types
      • Support for the following strided batch mode:
    • Added new generic APIs and improved performance for sparse matrix-sparse matrix multiplication (SpGEMM): cusparseSpGEMM_workEstimation, cusparseSpGEMM_compute, and cusparseSpGEMM_copy.
    • SpVV: added support for __nv_bfloat16.
