deep space computing employees developed over the years the worldwide first framework for distributed computing over a peer to peer network, called Global Processing Unit. More details and screenshots are available on the project site.

The screenshot below shows the main GPU client while performing three computations in parallel.


There is also a 3D frontend to show how many nodes are connected with each other. Lines between nodes are connections among computers and their color represent how much TCP traffic goes through the nodes. 


 The GPU client is presented in the paper below. Click on the image below to open it.
