Why the Virtual Machine is not using all my CPU cores?

The new VBoxWrapper does not support more than 1 core currently.

(In any case, due to the limited use of multi-threading for the current application, only about 1 and a half cores can be utilized in practice).

Our older CernVM Wrapper does support multi-core systems. However, we only used at most two cores, because the current experiments will not benefit at all from 3 or more cores. Thanks to this, your BOINC client will be able to run other projects in the free and available cores of your computer.
