Multiple Processor Monitor

Multiple Processor Monitor is a simple-to-use app designed for the Yahoo! Widget Engine, that allows you to keep an eye on the activity of multiple core systems, as the name suggests. It can be easily installed and set up.
The lightweight widget is wrapped in a simple interface, consisting of a small window that you can move to any position on the screen, with the help of the mouse cursor.
By default, the frame's opacity level is set to 0%, so you can get started by adjusting this setting in the Widget Preferences panel, available through the right-click menu.
The primary window of the application is straightforward. Multiple Processor Monitor displays a graphical representation of your computer's CPU cores (up to four) to easily spot spikes in terms of the current consumption, together with the percentage value for each core.
Unfortunately, users are not given the possibility of recording this activity and saving it to file for further evaluation.
Aside from changing the window's background opacity, you may also select the update time interval and colors for the background, graph and font. Thanks to the default options provided by the Yahoo! Widget Engine, you can also enable the frame to stay on top of other windows, to ignore mouse events and to prevent dragging.
Multiple Processor Monitor is very light on the system's resources, since it requires a very low quantity of CPU and memory. Its response time is very good, and the utility performed smoothly in our tests, without hanging, crashing or popping up errors.
Since the Yahoo! Widget Engine project has been discontinued, this useful app shall not be receiving any further updates. However, Multiple Processor Monitor can still be of service to all users who want to monitor their cores' activity, such as avid gamers.
