The best way to get POEM WU's is to use the project updater. It automatically spams the update function for you at a preset interval of your choice wink.gif
There's a thread and download link here
I use it and on a weekday, it works well - I get 100 WU's at a time. On a weekend they always seem to run out of WU's redface.gif

I haven't experimented with how many threads per wu is optimal but an overclocked i7 3770K can't keep two 7950's running at full speed so I'd say that more than 0.5 is needed

From what I recall, 0.5 is fine, even if you set it to 1 it will not really increase ppd. POEM is bandwidth limited more than anything. At one point one of the POEM mods let me know that it is also GPU internally bandwidth limited, this is partially why Doc Gonzo's 7850 could put out as many ppd as 7950 or 7970.

I tried going around the CPU limitation, but no matter what I did it still hogged quite a bit of CPU time.  That is the main reason I stopped running it.  There are quite a few CPU projects that are interesting to me, and I couldn't run them on more than a few cores if I was running POEM.

 

Let us know if you figure something out. :thumb:

The POEM++ OpenCL project 'gpucrystal' is going to be finalized soon. In other words no more work units will be created, and as soon as the circulating jobs are finished, the queue will run dry.

We are currently working on a follow-up project, which will start in January 2014, accompanied by a new POEM release.

Thank you all for contributing your GPU power to this project. Please use this POEM OpenCL rest period to support other great projects in the BOINC network.
I'm looking forward to see your GPU back at POEM next year.

No more GPU WUs til next year (Jan 2014)

POEM++ 2.0 Release
I've just updated the POEM@HOME Binaries to Version 2.00. This is the first big step for our new GPU project. I'll have to adjust some parameters of the new work units, and will send them out at the end of this week.
I'm confident the errors which occurred during the test phase have been resolved. If you encounter any problems nevertheless, please report it in our message boards.
