Since the new Raspberry Pi 2 in February, not only has sales record been broken in all this time, demonstrating once again that both the community and the interest in the platform is more alive than ever, but that practically all users are more than interested in getting a software simple to use that is able to display on the screen the workload supported by each core of the card easy to understand way.
The time has finally come to share one of the best projects in this sense that I have been able to find. Its author is a certain Dave, little else I have gotten to know about it, that he has managed to implement software capable of making the CPU itself send a certain number for each core at certain times, these numbers are represented in a graph at screen level with which to understand, when the workload is greatest in one core or another. Personally I have to admit that this software has been great for me when doing performance tests with various programs «chorras»Where I was trying to test parallel programming concepts.
If you are interested in this peculiar software, tell you that it is available in a GitHub repository. All the configuration is done from the executable itself, so you just have to install the program and make it run. By way of comment, perhaps the only drawback you may have is if you have a web server on your Raspberry Pi since you probably have to change ports.
