	I am not sure where I have set what? But when SETI is running, just uses 50% (1 core) of my dual core PC.. When Milkyway runs, is uses 2 CPU.. Also when they are running together.. Milkyway superseeds SETI and suspends SETI's work and hogs up both CPU I have checked preferences on website and I can't seem to see why it is doing it.. I want both projects to use 1 CPU each when running together.. or perhaps make SETI work superseed Milkyway's Plz help :)

	SETI tasks are all single threaded. Many Milky Way tasks are multi threaded. Multi threaded tasks will use as many CPUs as you have up to some number N processors. Therefore when Milky Way is running, it will use both of your processors. SETI is only a single threaded process. You need to have enough work from SETI to use both CPUs (2 tasks). To do that, you need to increase your work buffer a bit. Set "Extra work" to large enough so that it is larger than any single SETI task. ____________ BOINC WIKI
