I want to run one workunit at a time on a dual core cpu computer.
The BOINC Manager 5.4.9 for Mac OS X tends to run two workunits at a time on my dual core cpu computer.
In order to run only one workunit at a time, after downloading data, once suspend all work units, and enable only one.
It seems to me this can only be done manually.
Please advise me if there is a way to do all the way automatically.

There's an option in your GENERAL PREFRENCES:

> On multiprocessors, use at most "n" processors

--- bt

Thanks; I made it.

1. Edit General Preferences - to use at most "1" processors.
2. BOINC_Manager > Projects > Update

Fu-Ma
