A Nice Overview Of The ROCm Linux Compute Stack

[bridgman]

I was thinking that AMD was adapting OpenCL to Torch 7, throughout the base Cientific Language( Lua ), and not a adaptation to other language.. This changes a bit, my requirements for Rocm, since I wanted it to use Torch7 on OpenCL( with the real Scientific Lua Language )...

AFAIK the Torch 7 support was via HIP, not OpenCL.

Sorry, I meant most open noch, wie sie GPGPU betrifft..

Thanks. I think there os Threadripper is first product for project I mentioned

[TemplarGR]

I am just sad my Tonga is not yet supported. Fingers crossed for inclusion in the future!

Is PAL would work with RX 470?
Is ROCm would work with RX 470, if CPU and board does not support atomics? If not, how it would fail - kernel module will threw an error or OCL app will fail somehow?
Would it will be possible to use Orca or PAL with upstream Linux 4.18 without kernel module from AMD-provided packages? (Here I imply upgrade from Kubuntu 18.04 to 18.10 with installed OCL stack.)
Which one OCL stack is 100% open source?

There is some hope on Tonga, see the last comments over here: https://github.com/RadeonOpenCompute/ROCm/issues/509

Ok, Thanks for the clarification.
In fact it opens more possibilities, using HIP, for porting code and to start from another perspective too.

Rocm Page changed Again:
Current CPUs which support PCIe Gen3 + PCIe Atomics are:

• AMD Ryzen CPUs;
• AMD Ryzen APUs;
• AMD Ryzen Threadripper CPUs
• AMD EPYC CPUs;
• Intel Xeon E7 v3 or newer CPUs;
• Intel Xeon E5 v3 or newer CPUs;
• Intel Xeon E3 v3 or newer CPUs;
• Intel Core i7 v4, Core i5 v4, Core i3 v4 or newer CPUs (i.e. Haswell family or newer).

But then:

• AMD Raven Ridge APU are currently not supported

I would like to know what APUs are infact supported

I would like to know what APUs are infact supported

AFAIK, Raven Ridge will get support in future, just was missing support somewhere last I heard.

If so they should remove the
"

• AMD Ryzen APUs;

"
from there, because they don't have support!
In that way the project would seem more transparent..

[chithanh]

I guess the wording is confusing.

What they mean is that Ryzen APUs + discrete graphics are supported.
Ryzen APUs and the internal graphics are not yet supported, but that is about to change I think.
