I setup all device profiles with a "Connect to network about every" to 3 days and I get a total of 345 hours of workload for my 8 cores machines which mean 43 hours per processor.
It means that I get less than 2 days of work. If I "Connect to network about every" 3 days what will I crunch for the remaining day?  |

Depending on the speed of your machine you may have temporarily hit the wall, speak the daily maximum download which is like 50 per day per core. Had 1 yesterday:
----------------------------------------23/07/2007 22:05:02|World Community Grid|Message from server: No work could be sent. 23/07/2007 22:05:02|World Community Grid|Message from server: (reached daily quota of 50 results) Crunch a little bit so it will be able to determine the real performance. The next day another 50 is ready to backfill your queue. 3 Days though is not 3 days as there is a safety margin build into the algorithm of 1 day. Here's a wiki page with a table that shows what is given with different settings and deadlines. The WCG deadlines are a mix of 9 and 11 days, so the maximum average of 10 would apply giving a best value of 4.24. http://www.boinc-wiki.info/Work_Buffer Assuming you are on 5.8.15 or 16, with the next version there is an extra buffer option. While testing this, I've set it to 1 day connect, for the daily flushing and 3 days extra buffer. Works perfectly and got a queue of almost exactly 4 days worth.

When/if you hit that magic 50 workunits/day, try to connect every day. It's still a good idea to trade daily.
----------------------------------------Any day that gets no downloads is wasted. It will only download 50 per day. I usually only had that problem after an extended offline time. I might send in 75, but only get 50 in return. After a day of 50 or two it would settle down. I always had enough in the queue to get me through it without going totally empty. That showed up a lot with the fast running GC project, but should be less visible with the larger FAAH and HPF2 workunits.

Sekerob, that wiki page is wrong. Worse, it's wrong in different ways depending on which version of BOINC you use.

Good. I hope the author(s) read this and correct before the next poor soul falls victim to tweaking the buffer settings.
