The stickied thread says max runtime = 18 hours
----------------------------------------The runtime for a wu as calculated on a couple of rigs here is > 1 day and rising The actual average runtime on the above rigs is around 9 hours I guesstimate that the maximum loadout is around 5 or 7 days at best but: No tasks sent Tasks won't finish in time: BOINC runs 100.0% of the time; computation is enabled 100.0% of that Whereas I run into the maximum number of wu's issued limit on other projects with a quicker runtime, here The runtime calculation is nowhere near. Can we really not do better than that ??  |

There are two problems, the first is that BOINC isn't designed for a project like WCG with more than one sub project, so that messes with the normal estimation measures (I believe the WCG tech's have the main estimation measure turned off)
The second problem is that CEP has a wide variety of runtimes, and the estimation takes a bit to level out when the times change. The 18 hour limit is saying that when the CPU time gets to 18 hours the work unit will end even if it isn't finished. On the other hand the estimated time is just the scientists trying to pick compounds that won't run for more than 18 hours on an average system. The estimated time is what BOINC uses to calculate if you'll be able to finish all the work by the deadline, not the previous run times. |
