Emulating Volunteer Computing Scheduling Policies

David P. Anderson
2011 2011 IEEE International Symposium on Parallel and Distributed Processing Workshops and Phd Forum  
Volunteer computing systems such as BOINC use several interacting scheduling policies, which must address multiple requirements across a large space of usage scenarios.  ...  In developing BOINC, we need to design and optimize these policies without direct access to the target nodes (volunteered PCs).  ...  BOINC [1] is the leading software platform for volunteer computing. The BOINC server software allows scientists to create projects, each of which operates a server that dispatches jobs.  ...

Quality of Service of Grid Computing: Resource Sharing

Xian-He Sun, Ming Wu

Balancing Scientist Needs and Volunteer Preferences in Volunteer Computing Using Constraint Optimization [chapter]

James Atlas, Trilce Estrada, Keith Decker, Michela Taufer
2009 Lecture Notes in Computer Science  
BOINC is a middleware for Volunteer Computing. In BOINC projects, heterogeneous resources distributed across the Internet are used for large-scale scientific simulations.  ...  To address this problem, we propose a novel optimization procedure based on constraint optimization techniques that actively allocates volunteer resources to improve project throughput and, at the same  ...  Projects are independent and have different resource requirements. Volunteers participate by running the BOINC client software on their computers (hosts).  ...
