hipSPARSELt API reference guide

hipSPARSELt is a library that contains basic linear algebra subroutines (BLAS) for SPARSE matrices that are written in the HIP programming language. It sits between the application and a ‘worker’ SPARSE library, marshalling inputs into the backend library and marshalling results back to the application. Supported backends are rocSPARSELt (included in hipSPARSELt) and cuSPARSELt.

hipSPARSELt supports AMD’s SPARSE matrix core technology on AMD RDNA/CDNA GPUs. It is designed for use with C and C++ code.

Note

Code for hipSPARSELt is open source and hosted on GitHub.

The API reference guide is organized into the following sections:

• ROCm & CUDA supported functions

• Data type support

• HIP device and stream management

• Storage format

• Porting from CUDA to hipSPARSELt
