GPU app release windows
The windows GPU app release is ready, but not yet tested. As I am not at home during my holidays, I do not have access to the Windows test machines. It's tested on my private AMD 6310 and works there. Whoever wants to test (especially nvidia!) please download this: http://boinc.fzk.de/userdocs/temp/poemclwin.zip and start runthis.bat . A textfile stdout.txt will be generated, it would be nice if you post the last 20 lines of that file here. Thank you!Der Windows GPU app release ist eigentlich fertig, aber noch nicht getestet. Da ich während meines Urlaubs nicht zuhause bin, habe ich leider keinen Zugriff auf die Windows Testrechner. Auf meinem privaten AMD 6310 laptop ist es getestet und funktioniert. Wer beim testen mithelfen will (vor allem Nvidia!), kann einmal http://boinc.fzk.de/userdocs/temp/poemclwin.zip herunterladen, runthis.bat ausführen und nachher die letzten 20 Zeilen der stdout.txt hier im Kommentarthread posten. Danke!Edit: The AMD/ATI version is released now. The nvidia version still has some problems initializing.

Great news and better news.
I have been testing POEM GPU work:
h/w - Phenom II x6, 8GB RAM, AMD HD5770 GPU
s/w - Win7-64, Catalyst 11.12, BOINC 7.0.3 **

** QUOTE "And yes, you have to run the pre-release version of BOINC to get work, i.e. 7.0.3 for Windows or 7.0.2 for Linux..."

The great news is the Windows ATI-OpenCL client is working and working well. (Nvidia not working properly yet - work in progress)

The better news is I'm passing lots of people in the team today :P

One person reports unable to run on HD4550 with older and newer drivers Win7 (arch not specified)
Another says "that ati 4770 is working well in win7 32 bit with latest beta Boinc ver and ATI drivers DL 29th Dec."

Another post points to the AMD/ATI Hardaware OpenCL compatibility list

So really, that is a broad brush and most cards should be working.

In the mean time I'll keep passing you fellows until you decide to take up the challenge

The ATI application also runs well under Win8 64 Dev (still only when starting manually, automatic startup will not recognise the GPU), using the latest AMD drivers and Boinc 7.0.3

My linux ATI box is correctly spec'd but not getting any Linux ATI work. Don't know why yet.
The Linux Nvidia box is not getting any either but I think I know why that is.

Some good news on the POEM Linux ATI front.
I got a post back from a member of [TeaM] that prompted me in the right direction and I sorted out my linux box.
So, now we have a working Linux_AMD64 ATI HD5770 box getting work on poem.

Don't ask me about CreditNew because I do not have a polite answer

In the mean time ...
There is now a great new way to provide huge amounts of excellent results to the POEM@Home project.
Get your GPUs on it.
With Windows and Linux working you have NO excuses to hide behind. :P

Just you wait and see!

It uses to much cpu to feed my four gpu in my xp64 system and cuts into my WCG crunching :P

[Dirk Broer]

Just you wait and see!

Wait a bit longer, got two computation errors after -too many- hours of computing...
Just because I suspended them after they took more than 15 hours and had not finished yet.
Does anybody know how fast a HD 4770 is supposed to finish a POEM WU? They load down as 1h 53m WUs....

Solved: It needs a complete core! While running it already states .94 CPU, but they can better change that to 1.0 CPU
If I disable one task in a quad (and set all projects not to receive new work) the estimated end time goes down with 1 minute per second (estimated time was up to 22 hours, it basically is just counting tachyons and not doing a thing while not being fed a complete core)

Just joined the project yesterday with a 4870 and two 6850s. It seems that the 4870 works best with the app_info.xml set to running three WUs (0.33) with 0.67 CPU cores each. While the 6850s seem to work best at 10 WUs(0.1) with 0.4 CPU each. Around 150,000+PPD for a single 6850 alone so far (about 2 hours and 20 minutes to complete 10 WUs simultaneously, which is about 14 minutes per WU).
