HcSPARSE - Deprecated Software

the HcSPARSE project has been deprecated. Please use rocSPARSE instead.

A. Introduction:

This repository hosts the HCC implementation of linear algebraic routines for sparse matrices/vectors (HcSparse), on AMD devices. To know what HCC compiler features, refer here.

Following list the routines that are currently supported by HcSparse that are grouped into four major categories.

1. Level 1 BLAS Routines:
   • axpy : Product of Sparse Vector with constant and followed by addition of dense Vector.
   • dot : Dot product of Sparse Vector with dense Vector
2. Level 2 BLAS Routines:
   • csrmv : Sparse Matrix - dense Vector multiply (SpM-dV)
   • csrmm : Sparse Matrix - dense Matrix multiply (SpM-dM)
3. Level 3 BLAS Routines:
   • csrgemm : Sparse Matrix - Sparse Matrix multiply
   • csrgeam : Sparse Matrix - Sparse Matrix addition
4. Conversion Routines:
   • dense2csr : Dense to CSR conversions
   • csr2dense : CSR to Dense conversions
   • coo2csr : COO to CSR conversions
   • dense2csc : Dense to CSC conversions
   • csc2dense : CSC to Dense conversions
5. Input Reader functions:
   • mm-reader : Functions to read matrix market files in COO or CSR format

B. Key Features:

• Supports COO, CSR, CSC, Dense matrix formats.
• Level 1 Routines for sparse vector with dense formats
• Level 2 routines for sparse matrix with dense vector/matrix formats
• Level 2 routines for sparse matrix with sparse matrix operations.
• Conversion routines that supports conversion between different matrix formats.
• conjugate-gradients : iterative conjugate gradient solver (CG)
• biconjugate-gradients-stabilized : Iterative biconjugate gradient stabilized solver (BiCGStab)
