Seems, that you have a dual-core CPU in your computer. For each task you run, you need one CPU (or core). If you buy a quad-core CPU, you can run 4 tasks at a time, if you have a 2 CPU system, with 2 quad-core CPUs inside, you can run 8 tasks, and so on...

@totto73,

with a VM you could get 3 to run or with the venerable Hyperthreaded Dual you could too, but it does not exactly improve efficiency. More for the techno addicts ;>)

@Deepy,

If you select 3 WCG science projects you get work randomly from WCG based on availability i.e. what's in the feeders that moment. WCG over a longer period tries to balance things so that all the projects eventually get an even weight. Also since there are many 'project preference' crunchers, the mix that is left for the pool / all project / multi project crunchers is not squaring to begin with. For RICE on a mix project device I see maybe 1 in 10 or less as an indication.

Here a picture of how the joyride works out with 5 projects to manage:
