WCG: SETI Germany 8th Birthday Challenge Completed

Post by **Megacruncher** » Thu Nov 15, 2012 11:34 pm

Starting soon, sometime on the 16tj of November, another WCG challenge .
Leaving aside the mildly inconvenient 3 1/2 day overlap with the Einstein challenge this is the ideal opportunity to begin the WCG fight back & to sign up for running the Help Conquer Cancer on your ATI or NVidia GPU card.
The stats are here http://www.seti-germany.de/wcg/statisti ... llenge.php

We are doing surprisingly well here, if you consider that this project is a team weak point. After the first day we find ourselves 34th out of 147 active teams. Top quartile.Yeah!

... I notice that team 777 has actually managed a negative score. Does this mean their doing the course backwards or is it a subtle new strategy in competitive boincing ?

DSFL is probably a good project to go for at this stage. No wingman to wait for.

On it. WCG seems to be a lot less easy to manage than the other BOINC projects.

Joined in late, but better than not at all. I'll make my modest contribution here for a spell. Cheers!

On the help conquer cancer NVidia app I seem to be running at about 80% failing on computational error after 2 secs. Is this normal ?
And their stats take forever to update.

No it is not normal - you might like to check for errors in the various logs. First is the Event Log which you can view in the BOINC Client - sometimes there is a hint there as to why it is not working.

Next you can take a look at any STDERR output which in WCG's case means you have to look at the BOINC Data directory wherever it happens to be on your PC. Usually it is quite recognisable given the files in it (Try "C:\Program Data" if it's a new Windows install, "/Library/Application Support/BOINC Data" on OS X and "/var/lib/boinc-client" on Linux.

Take a look at the SLOTS sub-directory and find the one with obvious WCG units in it - then look for a STDERR.TXT file. You have to be quick and capture these files before another WU starts... and there will almost certainly be more than 1 slot running WCG WUs. On normal BOINC sites these are the STDERR files displayed when WUs fail.

I should note that STDOUT.TXT if it exists is not usually very interesting in these cases. In the main BOINC Data Directory STDOUTDAE.TXT is what's displayed in your Event Log on the Boinc Client.

I haven't found anything yet but as a general help you can try (if you have not already done so):
1) WCG GPU FAQ: http://www.worldcommunitygrid.org/help/ ... rtName=GPU
2) WCG GPU Support Forum:http://www.worldcommunitygrid.org/forum ... ?forum=560

Some WCG projects use a lot of wingmen - particularly Human Proteome Folding which pushes out 19/20 wus and requires a minimum quorum of 15 before it hands out results. not good for comps as it takes a long time for results to come in. Most of the other projects push a couple of WUs out and require a minimum quorum of 2 results which agree (like Einstein@home). WCG does allow you to select the projects you run...

Welcome back Cyclone... good to see you again! :)

Anyhow we are in 33rd place which is quite respectable out of 154 actively participating teams & not far behind UBT

Still holding 33rd...

And 33rd it was at the end which I'm quite happy with.
