I'd need help for getting some GPU tasks. For past five days, I've got only four tasks. It seems that my client wont poll for new tasks too often... it's already on hour from last poll. Is there a way to make client connect more often? You could try this on the command line. Simply go to /var/lib/boinc and run: while (true); do sudo -u boinc boinccmd --project "http://www.worldcommunitygrid.org/" update; echo "Update triggered $(date)"; sleep 300; done That should do the trick... Is there a Windows version of that trick? Actually it is not a trick. Try this: Open "cmd" and cd to "c:\Program Files (x86)\BOINC\" then run: FOR /L %N IN () DO @date /t & time /t & boinccmd --project "http://www.worldcommunitygrid.org/" update & timeout 300 > NULGood luck.

Thanks Andrew and kwolff! Made a simple windows scripts and scheduled it to run every 5mins. Now I got a batch of 15 gpu WUs , and my gpu is happy for the next 30mins :-)

I agree with Kittyman.
Unless we've got explicit approval from the WCG staff to request GPU work every two minutes, indefinitely, I'm not going participate in anything remotely similar to a DDOS attack. Ever since Beta work units were available, I started getting "Project communication failed: attempting access to reference site | | Internet access OK - project servers may be temporarily down." I don't know what's going on server side, but it seems to coincide with whenever a batch of GPU work was released. So I'm not sure if the World Community Grid servers are ready for the most active users to start contacting them an additional thirty times an hour, per host (720/day). Especially if that activity doesn't' result in a single extra work unit being done that wouldn't otherwise be assigned and completed by a different donor. |

All these comparisons to DDOS-attack are ridiculous when users are requesting work. The bandwidth / linespeed is more relevant, so all users visiting the WCG-webpages is probably more demanding than workrequests. The server(s) should easily survive requests up to 100.000 / second. |

2006. Is that still relevant? Anyways I agree that the comparing requesting work units every 5mins to ddos attack is a bit ridicilous. For CPU units, when you have 24 cores crunching WUs that take 1-2 hours to complete each, the scheduler seem to do it's job just fine. However, in the projects that has limited supply of WUs things seem to be a bit different based on my experience. |

Linux, assuming being run from the directory with boinccmd watch -n 300 ./boinccmd --project http://www.worldcommunitygrid.com update anyone comparing this to a DDoS doesn't know what they're talking about, and it's quite hilarious to hear such hyperbole.

Sure, it's different to a DDoS webserver attack - but as Rom points out, it has the capability to become a database attack. However, BOINC is usually optimised to back out of work requests quickly without bothering the database when no work is available.
I understand that WCG have significantly enhanced their server capacity in anticipation of the work surge, but we should dismantle the scripts once work has ramped up to flow freely. |

It's selfish and greedy to override the default WU request interval of the client. The limited work currently available is being taken from those of us who choose to respect the default behavior.
----------------------------------------And I seriously doubt it is primarily because people are genuinely interested in helping scientific research and making the world a better place, but more likely an [EDITED] contest to see who can earn the most points and show off to the world how superior they are with their BOINCstats signature. It is undeniable that it takes more network bandwidth, CPU processing time, disk I/O, disk space for request logs generated and more load on whatever backend data store is being used. If a large number of people start running these scripts, it will require an increase in resources dedicated to this project. Someone, somewhere will have to pay for this. If your GPU is idle when not processing OP GPU tasks and you want to do work, then sign up for Folding@Home or some other project that uses a GPU.
