We have finally begun to automatically deliver CUDA work & applications (plan class "ABP1cuda23") to machines that satisfy the following requirements:

- enabled NVIDIA GPU work in Einstein@home preferences
- NVidia GPU with at least 450MB of free memory
- Display Driver version 190.38 (&up), i.e. CUDA 2.3 capability
- BOINC Core Client version 6.10 (&up)

CUDA Beta App testers should drain their work cache and switch back to the normal project work.

ABP1 CUDA applications

Are these the same 'hybrid' applications, requiring a full CPU core in support, that we were testing in Beta, or have you been able to tansfer more of the other calculations (apart from fft) onto the GPU?

These are basically the same Apps as have been in Beta est. They still require a full CPU core.

They require a core at 100% or we can find a lower value so that other projects can use it?
I'm running it with 0.3 CPU + 1.0 GPU.

The new apps are not shown on

The new apps are not shown on the apps-page: http://einstein.phys.uwm.edu/apps.php

Now it would be nice, if you could select, that your CPU only gets tasks for S5R6. Because the ABP1-work is done at the GPU.

And did you forget to include a fifth piece of requirement - Not meant for Macs...!!!

Yep. Stupid as it is, NVidia hasn't yet delivered their promised 64Bit CUDA libraries for Mac OS X. As soon as they do, we could build and send out CUDA Apps for Macs, too.

It's not, at least not exclusively.

I find that very bad that it needs a 100% core and that you set cuda on Enable as default.

It's a problem with that on a few pc.
I run Einstein on a pc and folding@home on the GPU.

It was only by accident that i discovered that cuda was enabled today.

The only problem I have with this, is, it is using 100% CPU, while using only about 4% of the GPU from a GTX 285 card.

This was my first AND my last

This was my first AND my last ABP1 so called "CUDA" WU!

This application is a complete nonsense! It's occupying 1 CPU-Core AND a GPU for more than six hours now and most of the time the GPU is nearly IDLE, temperature is at 49°C now! In this amount of time the GPU could have crunched a hundred of Milky Way WUs or dozens of Seti or Collatz WUs.

Why doesn't it suspend after a given time? Are there no checkpoints in CUDA apps or what? Others are way too short to suspend, so there's not much to compare for me.

If that's what you call CUDA then cancel it and revert back to CPU only WUs. This is nothing more than a bad joke. Sorry but I didn't contribute in beta test phase, otherwise I would have mentioned this much earlier.
