Lately one of our crunchers got very many gpu credits over a very short time and was scolded for that in the forums for being a cheater. These credits were awarded falsely and should be taken back now. One of our members contacted him privately to investigate and it turns out the "cheat" was an approach to update old core clients to use gpus. Our validator didn't catch it for a reason, which we cannot specify now (as it is not fixed yet). We will tell you how this was possible, once it is fixed. The user will be unbanned. Thanks to everybody for bringing this to our attention!
Zuletzt hat einer unserer Cruncher sehr viele GPU credits über eine sehr kurze Zeit erhalten und wurde dafür im Forum als Cheater markiert. Es stimmt, dass die Credits von unserem Validator vergeben wurden, obwohl keine echte Arbeit geleistet wurde. Wenn man sich die Files anschaut, die der Validator validiert hat. Wir werden euch sagen, warum und was das besondere dieser Dateien war, wenn wir das Loch im Validator gestopft haben. Der User darf nun wieder mitcrunchen. Danke für alle für das viele Nachforschen!

The mentioned false computations claimed most of the available GPU jobs in a very short time, that is why there is now a lack of them.
New jobs will be sent out as soon as the results of the past few days are cleaned up.
I can't give you a fixed date, but I hope this will happen soon.

Best,
Thomas

Hello everyone,
I know this is offtopic here, but the work distribution for GPUs has been restarted, so I see a lot of the following messages at my boxes since last night:
18288 Poem@Home 04.03.2012 11:35:17 [error] Error reported by file upload server: Server is out of disk space
18289 Poem@Home 04.03.2012 11:35:17 Temporarily failed upload of poempp_gpucrystal_1330763468_870792393_0_0: transient upload error

This means the completed results are now piling up on my boxes...
Any chance this only has got to do with the db_purge job marked as not started?

Thanks and Cheers,
Christopher

Dont unban them. As their action/s could have invalidated or corrupted the hole project. This project can help to save lives we dont need selfish idiots running or messing with vital research.

There are always slow downs, CreditNew and the sensational outputs for 'artificially' long running and slowed down tasks probably was worse in total effect, adding penalties for speeding up GPUs by increasing load on top of that.

Let's look forward now and hope things get to next level. :)

Hi
This is the first time I have posted on this site and the reason I'm doing so is because when BOINC tries to open Poem files I get a virus alert from my Avast! anti-virus program. For the moment I will pause Poem but does anyone know what this is all about?
