I setup a 32 bit Ubuntu 14.04 linux system with 2 cpus with 4 cores each.

Am I limited to have to one task in my Queue or does it just take awhile to get more tasks?

Edit:
Sorry, I guess it didn't want to give me any new tasks for 3 hours.

It can take a while, as BOINC "tries out" this new application.

There's also a one hour time delay after contacting the server before you can get more work.
And don't keep clicking "Update", as that will just reset the delay.
