Parallel Computations In The Volunteer-Based Comcute System

The paper presents Comcute which is a novel multi-level implementation of the volunteer based computing paradigm. Comcute was designed to let users donate the computing power of their PCs in a simplified manner, requiring only pointing their web browser at a specific web address and clicking a mouse. The server side appoints several servers to be in charge of execution of particular tasks. Thanks to that the system can survive failures of individual computers and allow definition of redundancy of desired order. On the client side, computations are executed within web browsers using technologies such as Java, JavaScript, Adobe Flash etc. without the need for installation of additional software. This paper presents results of scalability experiments carried on the Comcute system.
