There is NO SUCH THING as an "ATI" work unit.

All work units are either "Astropulse", or "Multibeam", and as such they are available to any processor that is capable of processing them. At the time of a processor making a request the server looks to see if it has any work units available in the delivery queue, and if there are any restrictions on them being delivered to that processor. These restrictions may be "human", in the form of "don't send my any Astopulses", or "machine", processor is judged to be incapable of handling a particular work unit. Provided the work unit and the limitations are OK, then the work unit is set as a task for that particular processor.

The number Asropluse work units that can be split from a tape is significantly smaller than the number of Multibeam work units that can be split for two reasons: There is no overlap between Astopulses, but there is an overlap on Multibeams; and the bandwidth of an Astropule is considerably larger than that of a Multibeam. Each tape is split twice, once to give Astropulses, and once to give Multibeams.



(In this context "processor" is either the CPU, or GPU on a given cruncher)

But, But, But, there must be! People keep asking for them by name.
All those people couldn't be wrong, could they?

(btw, I knew, but didn't feel like explaining when others can do
a much better and more thorough job of it.)

AstroPulse and MultiBeam work can be processed by CPU and GPU.
Currently there's a few new OpenCL apps.for AMD/ATI GPUs

And MultiBeam can be computed by CPU stock/optimized just as on ATI & NVidia GPUs.

I thought I'd slipped a cog or two, only machine with work to do is on one. . . of the ones I stuck a nvidia board into couple of years ago.

felt so bad about lack of work earlier today bought another laptop, probably should have read these post first. not wasted money, been need a new one for some time now..

After a couple of works of almost never getting and GPU work for Seti, I've finally re-attached to another project (as someone said above "starts with E, ends with N - figure it out) just so my GPUs don't sit idle.

Work has been available & downloading for several months now, with the odd short break here & there.
There just hasn't been much of it available over the last couple of days.

For the past 2-3 weeks I've been getting "no work available" for GPU consistently. One or two tasks will slip through for either computer occasionally, but not nearly enough to keep them busy. Grant, I'm not sure about "Work has been available & downloading for several months now, with the odd short break here & there. There just hasn't been much of it available over the last couple of days." unless by "days" you mean weeks. Even when I do get a GPU task, it usually takes 2-12 hours to download because I don't sit there and mash "retry" every 10 seconds. It's just not worth the headache to me right now.

I see now Einstein has GPU tasks available and I don't have to deal with the frustration factor of Seti's queue problems.

I'll put Einstein back on hold once (if) Seti gets it sorted out.

By days, i mean days, as in since the 4th of this month. Prior to that there has been plenty of work available, other than when the system was down for the weekly outage. And even with the present shortage of work, i was still getting some with every 3rd-5th request.
Now the shorty storm is over, and i've processed most of the ones i had in my cache, i'm probably getting work on every 4 in 5 requests.

I've got my hosts file to use only the one download server, so i don't have the download issues of trying to download from the one that always times out.
At the moment some downloads are at about 15kB/s. For the last few weeks most of the time they've been about 5kB/s.
