One per CPU. Crunching more than one is actually a little slower (due to the time it takes for the OS to do context switching). ID: 87158 ·

If so, this is an error if two are running at the same time. You need to change your Preferences on Your Account at the SETI site to tell it NOT leave the application in memory.

Good one... didn't think to check his account/host/os info before responding and wasn't thinking HT. ID: 87199 ·

As Holmis mentioned, you can go into your account settings and tell it to only use 1 CPU on multi-CPU systems. That will tell BOINC to only use one of your 2 virtual CPUs, and so only use about 50% of your hyperthreaded CPU. I hope that helps...hyperthreaded CPUs are a little confusing at first, but they are quite good at doing 2 SETI WU's at the same time--about 30% better throughput than without hyperthreading.
