Main Page: http://www.thesonntags.com/collatz/index.php Collazt is one of the possible projects for a future Sprint race in the Formula BOINC race, so I thought I might want to get familiar with it. This private project has a real axe to grind with spammers, and doesn't allow you to simply join from the BOINC client, you have to join from the home page, and you have to have an invitation code. Additionally, users without credit will be deleted, and so will clients/computers without credit. After you join, you might as well go ahead and set your preferences (GPU only for example) before you add the project to your BOINC manager. I have tried joining the project before, but never received my invitation code. So I tried again and now have it. It is spammerssuck and is subject to be changed without notice. On the main page, (linked above at the start of this thread) you will need to carefully read the system requirements. What I missed was that you need to download and install both x86 AND 64-bit versions of C++, found here. The instructions say it's needed for CPU crunching, but it is needed for GPU crunching as well, as I found out when all my tasks immediately showed computation errors on a GTX1080. (Then I got locked out of requesting more tasks for 24 hours, due to the errors. Just close and restart BOINC if that happens) In all, a real pain compared to most projects, and it feels a bit unfriendly in the forums when other's also missed the info on the main page. I have no idea why anyone would want to run this project.....oh, I see, uh, got a couple tasks in already, now I know why they run it... 36,000 points every 13 minutes is 4,000,000 ppd per 1080! More importantly, practically no CPU usage (0.7%). So now that the introduction for the new guys (myself included) is out of the way, how about an experienced Collazt user tell us what app_config to use for certain cards? My 1080 was at 90% usage already, but the more results the better!
