Phoronix: SUSE Continues Working On AMD HSA Support In GCC

SUSE in cooperation with AMD continues working on the HSA (Heterogeneous System Architecture) support inside the GCC compiler stack...

It's great to see the HSA GCC support coming together albeit taking longer than anticipated with originally it looking like open-source HSA would be usable around the end of 2014.

There's an important distinction between building up the core driver functionality (which we did deliver as planned in 2014) and building an ecosystem of languages and tools on top of it.

Better late than never. Where is this HSA optimised software? Closed or open source, I'd like to see real software that benefits from HSA.

It might be late but it's here, and i think bridgman makes a fair point.
It's good to see new things from SUSE and AMD.
I don't care if some think it's late, better late then never.

I guess the first thing you can look at is anything running on Catalyst OpenCL 2.0 -- it uses HSAIL and the HSA finalizer path for kernel code, but stays with the Catalyst OpenCL runtime in order to run on pre-HSA hardware.

OpenOffice Calc is an example of software that makes use of HSA and according to benchmarks it does make a huge difference for some operations: http://www.tomshardware.com/reviews/...cy,3899-5.html

Can I see HSA as a more efficient backend for utilizing gpgpu resources?
I would like to know if changing from a10-5800k to hsa capable kaveri+ resulting in better opencl performance.
And maybe change from my r7-265 for 285 for full hsa potential.
Thx for being in the forum, its nice to have someone who really knows the tech so we tech dummies can learn a thing or two.

Is this actually implemented? I know there is an OpenCL implementation, which probably benefits Intel just as much. I think HSA support was made on a custom version that was never distributed. I could easilly be wrong.
