CUDA vs. OpenCL development

Postby Stubb » Mon Sep 26, 2016 11:29 am

Looking at the release history, I'm seeing continual updates to the CUDA version and a two-year-old OpenCL version. I'm curious as to the history, as MAGMA looks like the best bet for an OpenCL variant of LAPACK, but the lack of updates doesn't instill confidence.

We are actually working on a new release of clMAGMA that would bring it closer to CUDA MAGMA, and thus easier to maintain and have regular releases. I expect a new release in November. Code should be available before then in the bitbucket repository.

Thanks for the quick reply. Will keep my eyes out for it.

Is there an FFT library that MAGMA users tend to utilize?

I think most OpenCL users would use the clFFT library (https://github.com/clMathLibraries/clFFT) from the clMathLibraries group (those who maintain clBLAS).
