[Newbie Question]GPU linear operation in R using openCL

Hi everyone,

I am a new user to GPU computing. I am interested in running regressions in R using AMD GPU. My first thought was to recompile R and specify the BLAS library option to the BLAS in APPML. But I just found out that BLAS in APPML does not have level 1 operations.

It would be so helpful if anyone has some ideas or directions on how to achieve this. Any comment is appreciated. All I want is some linear operation, regression on double precision level at this time.

Thank you

If you are looking for some BLAS level 1 routine, i guess you might have to implement it for now.

APP SAMPles may be of help to you. You might find your routine implemented somewhere in it

Hey Gautam,

Sorry for my late response. Thanks for the hint. Currently I have not had time to work on it yet. I will look at it.

Thanks
