Make use of all 4 cores?

Right now I have only one instance of "einsteinbinary_ABP1_3.05_windows_intelx86.exe" running using exactly 25% of my total CPU (Intel Q6600 Quad Core). Any way for it to use all of it?

Thanks.

EDIT

Figures, a minute after I posted that 3 more instances popped up...

Nevermind!
