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. |

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... while/do loop with list comprehension is not even necessary. just use the watch command. 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.

Yes. Greedy people are voluntarily donating their GPU and CPU time for free. Shame on them if they do this for a reason you wont tolerate. e: Btw, didn't find any clause at https://boinc.berkeley.edu/wiki/Boinccmd_tool that says that you should not be using this tool, which is shipped with your default boinc client installation. ---------------------------------------- [Edit 3 times, last edit by caitilarkin at Apr 12, 2021 6:26:44 PM] |

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. your link is in reference to submitting results (which can be done on ANY interval), not requesting work (which the interval is limited by the project). apples to oranges. not aimed at you directly, Richard: with software as highly configurable as boinc with hundreds of different ways to tweak it and run it to suit your individual needs, trying to say what is "normal use" is HIGHLY subjective.

This second option only makes sense if you already have a VM running on the computer. For example, a few of my Windows machines have Linux VMs so I can run Linux-only when needed. Did this work? I have couple of extra VMs on my Win machine. do those VMs have GPUs passed through to them? this thread is about GPU work after all. GPU is run on the host machine, all CPU cores on VM(s). Or that's the impression I got. sorry, I misread your intent (had to go back and find the quoted response for context since this forum doesn't seem to leave you redirects back to them). I thought you were trying to increase your chances to get GPU work by making logical instances via VMs. This actually worked pretty well. VMs on host machine are dedicated to run CPU cores (I only use two Windows VMs on this, since this is propably a short term workaround. If this was a long term, I'd use several smaller linux VMs for better cpu scheduling) and the host itself has a dedicated profile to use GPU only. I've managed to snack GPU tasks every now and then. Running all cores on 2x windows VMs is roughly 10-20% slower, than running on a host machine alone. |
