Design of a Desktop P2P Computing Platform for DAG

DAGP2P is a desktop P2P computing platform specialized in the execution of parallel applications as DAG (directed acyclic graph). This platform makes it easy for scientists to create, deploy and execute their DAG. As it uses volatile volunteers´ computers without any guarantees, performances are difficult to obtain compared to big parallel machines. However, in a lot of cases, laboratories or scientists can not buy a such big parallel machines. Therefore we try to obtain the better performances that we can hope starting with theses volunteers´ computers. This article describes the components of the platform and shows the feasibility of the platform that we want to be simple, usable by the most of users as possible, extensible and fault tolerant. The security of our system is based on the concept of sandboxing.
