Xgesdd in clMagma

Postby paoloviviani » Thu Feb 25, 2016 5:05 am

Hello,
I see that Xgesdd (divide and conquer SVD calculation) is not present in clMagma, while it is present in CUDA Magma, there is any plan to implement it in the future?
Thanks!

Yes, we plan to add it to clMAGMA.

Dear Mark,
do you have any roadmap for the development of clMagma? Will the API be the exactly same as magma in the future (like no need of passing queues)? The possibility to switch seamlessly between magma and clmagma would be a killer feature for me.
Do you also have a timeframe for the dgesdd?

Thanks a lot!
Greetings,
Paolo

We're cleaning some things up in clMAGMA now. The goal is to eventually have identical interfaces, but that will be some time out -- maybe next year. One major difficulty of course is that matrices are passed different to clBLAS (as cl_mem and offset) than to cuBLAS (as pointer). In the next 2-3 months we should have a new release of clMAGMA out, and I can put the gesdd in that.
