    BLAS and FFT libraries for OpenCL

    wendellr
      Discussion about BLAS for OpenCL developing.

      Hi all,

      There is no BLAS library for OpenCL. I started to develop kernels for some functions in BLAS for dense matrix. Do you know any works on this area?

      Thanks for advance!!

          I use the conjugate gradient solver without preconditioners to solve a linear system Ax=b, where A is a sparse matrix. This method is iterative and uses some BLAS functions like Dot Product, Scalar Product, xAXPY and xGEMV (SpMV for sparse matrix).I've started to develop these functions for the OpenCL language and I've decided to share it.
