Is it possible to run more than one project at a time? According to the manager the resource share is divided equally however only one runs at a time?

Only one WU can be run per processor.

On a single threaded processor, like most AMDs, you only run one work unit at a time. With a hyper-threaded CPU, or dual cores, or dual processors, or dual HT CPUs (4 processors) will you see two (or more) WU running at the same time.

If you do have a multi-cpu machine and are not seeing this, you should check your preferences to see how many CPUs BOINC has been allowed to run on (default is 2).

You can see how many CPUs Windows thinks you have by CTRL-ALT-DEL and looking in the "Performance" tab. If it thinks you have one, you will only see one trace at the top right window. If 2, you will see two traces, on my Xeons, I see 4 ...

Over time, two projects are supported by "pausing" or "preempting" the running Work Unit and running another. In my case, I have 19 "CPUs" on 8 machines (HT gives you logical CPUs) and usually have 35 to 50 (or more) Work units in a partially completed state, with 19 in work...

Thanks ever so much for that, it now makes perfect sense.

There is more discusion on this in the Wiki where we talk to "logical processor" and "Physical Processor". In the Logical processor I also have images of a two processor and 4 processor task manager.
