New "SCALE" Software Allows Natively Compiling CUDA Apps For AMD GPUs
[quote]SCALE takes CUDA programs as-is and can even handle CUDA programs relying on line NVPTX Assembly. The SCALE compiler also is a drop-in replacement to NVIDIA's nvcc compiler and has a runtime that "impersonates" the NVIDIA CUDA Toolkit.


There is A LOT of tools to convert automatically (or semi-automatically) CUDA code to OpenCL/OneApi/SYCL/etc.
From AdaptiveCpp (using C++ as common language between Cuda/OpenCl/Sycl) to SpectralCompute, from HIPIFY to Coriander
But there are 2 problems:
- Nvidia could block your work (as they did with ZLUDA). I know, it's not a good thing for science to block others competitor, but CUDA is closed, so Nvidia can do it.
- Developers have to "try and learn" new sw. And i don't know if they have the desire to....

My guess given the present memory usage & performance, Single precision.


So, with top level Nvidia/Amd (both over 50 TFlops on SP), i hope we will have good scientific results!!

A little doubt/request: is a single or a doble precision this new gpu app??

I do want CPU work. If the project does not have CPU work it should give a different message that sets the client to no longer asking for CPU work.
and the message about the needed amount of RAM for GPU is plain stupid because I did not ask for that kind of work.


Me too.

Have you read the discussions over on Rosetta@home asking for Nvidia GPU support? The first efforts to try it showed that the minirosetta algorithms are too memory-demanding to make much use of enough GPU cores to get very much speedup on Nvidia boards with a currently reasonable amount of video memory. Therefore, such a conversion would require so much of a rewrite that it currently doesn't look reasonable.


This message is 14ys old, but it's true!!
Now we have a cuda/nvidia gpu app (or, better, we have a beta app)


Hope for an opencl/sycl/rocm/whatsoever app for other gpus (Amd, Intel, VideoCore, etc)!

It's been a week, and still no updated application.
I had been hoping there'd be a new one by now...


You are a "rookie" here.
So you don't know that the timing of Ralph is very randomic
And admins VERY rarely interact with the forum

If i remember correctly, they develop the code on Linux (and after they port it on Win and Mac)

Post:
It mentions that there are CPU tasks available, until it gets the update to not request them, then it doesn't mention the availability of CPU work after that.
And enabling & disabling the use of the CPU & GPU in various other combinations still results in no work- the GPU because it doesn't meet the memory requirements, but i've no idea why it won't send out any work to run on the CPU.
Probably because it uses the same application. And if it were it to send out work for the CPU, it would end up on the GPU- which it thinks isn't up to the task. And if it weren't up to the Task that would lead to all sorts of problems- hence why i suspect it's not sending out CPU work when requested.



Ok. I disabled the gpu option in my profile ('cause i have not Nvidia)
And the result is:
Tasks for NVIDIA GPU are available, but your preferences are set to not accept them

Waiting for cpu wus, if there ever will be

On the other, no Tasks at all due to being 1MB short of the VRAM requirement for GPU work, and the fact that it won't send work to the CPU.
Just 1MB...


:-O
I've not this problem. I've an AMD gpu with 4gb of Vram... :-P

It's something else they need to fix.

Not really, as they need to get the CPU part of it working as well, and make sure systems with other video cards aren't adversely impacted doing just CPU work.


No. If you don't have a gpu Nvidia you cannot download and crunch wus.
So, no Nvidia, no party

Updating BOINC to 8.0.2 did not help
The task fails with Exit status 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED after 25 mins


Did you see, in the other thread, the message about gpu ram (min. 6gb)?
Have you the latest gpu driver for your Nvidia?

Could be the problem is that the old application is trying to process the new Tasks because everything is so scrambled?


Maybe.
Now it's "0.02 (nvidia_alpha)" and i'm not downloading wus (now over 1000 in queue), probably because i've not a Nvidia gpu.

Yes. All errors also for me after few seconds
