Well, Bernd clearly stated that the primary goal is to test and develop OpenCL components for e@h. With this objective in mind: does it make sense for non-ATI-crunchers to participate in Albert? CUDA and CPU results can be used to validate OpenCL results, but then ...? I'm missing a little information about this. I'm getting WUs for two of my systems but the question remains: does Albert need / want non-ATI-Crunchers?

general question about Albert

I think I posted one or the other information already somewhere else, but to summarize:

If we wouldn't need non-ATI / OpenCL results, we would have disabled the respective application versions (as we had in the past).

Were it only for developing new versions of the existing BRP4 application we could as well have tested it on the main project. But it's not.

The OpenCL stuff requires not only new application binaries, but (for Einstein@Home) a couple of modifications to the server code, and currently special workunits, too. Apart from validating the results we also need to test how these changes work with the existing application verions.

However, currently we're getting by far the most results back from Windows CUDA apps (twice as many as from all other app versions together). We certainly need a few of these, but probably not that much.

I have the impression that a binary radio pulsar search on Albert@home is slower that a similar search on Einstein@home on my Opteron 1210 CPU running Linux at 1.8 GHz. But are those tasks identical or is there a difference?. I am glad to say I can see graphics on both.

This is an effect of the "special workunits" I mentioned. Indeed these are a bit different from the BRP4 ones on Einstein.

I'm busy trying to buy a decent ATI card, but money is tight this time of year...

Will resume CUDA/CPU work if it's helping.

wait for the 7000 series,

wait for the 7000 series, should be announced on monday. This new series will have much reduced power consumptions, and improved performance over the 6000 series. Or, you can see if you can find the new entry level ATI 6930.
