Why dGPU doesn't support Images and Samplers API? #15

Closed oscarbg closed 8 years ago

oscarbg commented 8 years ago

Hi, I see Images and Samplers API on KAVERI™ and CARRIZO™ chipsets.. why Fiji Fury dGPU via ROCK ROCR doesn't support? Fundamental HW limitation or software limitation that can be fixed?

As we said in the blog this ROCK and ROCR is early access developer release, We will be adding this feature at future date.

Thanks good to know.. a question about HSA Windows support? and dGPU HSA support on Windows? is supported officially? I say because seems Windows driver ships (or shipped once a time) with newhsacore64.dll and I found a project (https://github.com/hpcgarage/HSA-SDK-Demo) which seems to use that library to create a simple HSA app on Windows.. so Windows HSA library (newhsacore64.dll) already supports dGPUs (Fiji Fury?) like this effort (ROCR) does?

There is no support for HSA on windows. If you look at that link (HSA-SDK-Demo) you will see the following statement:

"Unofficial HSA SDK This repository hosts unofficial and unsupported headers for Heterogenious System Architecture (HSA) libraries.

The headers let you write applications which directly access low-level HSA interface, bypassing the OpenCL framework on top of it."

In no way does AMD sanction the use of this library or claim support for HSA platforms on windows.
