ZLUDA is back!! And now is focused on AI/Machine Learning.


First usable version of Zluda (Zluda 4.0) even if with limited, for now, capabilities.

P.S.
I'm curious to see when Nvidia will remove it. Again.

With hip-script you can run Nvidia Cuda and AMD Hip on your browser.

The Folding@Home team are migrating, for AMD gpu, from OpenCl to AMD HIP.
The tests are indicating that performances are doubled!!

No new work or applications to test, and broken stats & Ralph preferences for well over a month now.


Maybe they are busy celebrating the Nobel Prize... :-P

Post:
Boinc developers are working on Docker implementation to "abandon" Virtualbox, 'cause Docker is:
- faster
- easier to mantain
- gpus compliant

This could be a re-start of python application of Rosetta...

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.


ZLUDA is back!! And now is focused on AI/Machine Learning.

I've got few of these Rosetta 4.29 tasks too and they also Validate Error


Same here. Validation error despite, in the logs all seems ok...


At the end, seems that the validator is ok....

Post:
It is TOO BAD that volunteers get NO CREDIT for their 1000's of seconds of machine time when the failure is caused by the researcher submitting the broken work.
The same bug has been reported here for some time.


Some times ago, i proposed a "minimal credits" for bugged wus, a symbolical "premium" for volunteers that runs wus (and, sometimes, reports problems).
Obviously, no answer.

100 Tasks is not much, especially when there several hundred systems vying for what is available.

I remember when it was tried.


Mee to.
But, for example, you have to consider that this thread started 15ys ago.
And 15years, in gpu field, is something like 5 geological eras, both hw and sw.

Code on gpu is a difficult art....

The Rosetta application has been updated to include fixes to the core algorithm for protein modeling.


The description seems interesting, from a scientific point of view.

I'm still hoping for an updated GPU application.
Oh, and for them to bring the Rosetta main project servers back up again.


Especially the second one...

Please post issues with Rosetta 4.29 here.


Some details for this app? Bugfix? New functions??

Possible for SOME programs. No evidence that the Rosetta programs are one of these.


In the past there was no evidence that Rosetta runs on Nvidia gpu... :-P

Post:
Where's your evidence that the Rosetta programs are written in a way that will allow such a conversion without using only graphics boards with extremely large numbers of GPU cores?


No evidence.
Mine is only a little demonstration that is possible to avoid CUDA, if necessary...
