Is there a way to automatically restrict the number of work units that get actively crunched at the same time?
----------------------------------------I've recently moved over to the BOINC client from UD where the norm was to have only one work unit running. Even when I select one project on the WCG website the BOINC agent runs work on two units of that same project. I want the agent to work on one unit only, leaving any other units in a queue. Under UD this computer returned about one result per day – logically I would expect the BOINC agent to 'settle into that rhythm' of one result per day regardless of how many work units it has running. However I had an error message today that one unit was 1.40 days overdue and suggesting I abort it – so presumably my settings are too low to cater for multiple jobs (unless they were much smaller)? |

Perhaps you have a dual core computer, and BOINC also takes advantage of it and runs a job in each core. Most of us WANT to run as many as possible.
----------------------------------------HOWEVER <sulk...> you can always go to the device manager and change your profile if you want. The default is to run at most [4] multiprocessors. You can change that to [1]. There are four profiles, default, home, school and work. (If you recently changed something, even something like how much you use your computer, it may take BOINC a few days to settle down and figure out what's going on. The number of workunits should automatically adjust. You can also change the number of days between a network connection to control how many workunits are in your queue. From experience, don't go beyond 3 days. The queue can totally empty before getting more. When working well, you get more downloads with after every 1 or few you send up.)

BOINC will also run 2 work units simultaneously if you have a machine with Hyperthreading. The solution is the same though as pointed out above. Change the setting "On multiprocessors, at most use: 1 processors"
