We describe and evaluate a set of protocols that implement a distributed, decentralized desktop grid. Incoming jobs are matched with system nodes through proximity in an N-dimensional resource space. This work improves on prior work by (1) efficiently accommodating node and job characterizations that include both continuous and categorical resource types, and (2) scaling gracefully to large system...
We present some recent and ongoing work in our decentralized desktop computing grid project. Specifically, we discuss matching jobs with compute nodes in a peer-to-peer grid of heterogeneous platforms, and the implementation of our algorithms in a concrete system.
The goal of the work described in this paper is to design and build a scalable infrastructure for executing grid applications on a widely distributed set of resources. Such grid infrastructure must be decentralized, robust, highly available, and scalable, while efficiently mapping application instances to available resources in the system. However, current desktop grid computing platforms are typically...
We consider the problem of wide-area large-scale text search over a peer-to-peer infrastructure. A wide-area search infrastructure with billions of documents and millions of search terms presents unique challenges in terms of the amount of state that must be maintained and updated. Distributing such a system would require tens of thousands of hosts leading to the usual problems associated with node...
This paper presents an evaluation of three software implementations of release consistency. Release consistent protocols allow data communication to be aggregated and allow multiple writers to simultaneously modify a single page. We evaluated an eager invalidate protocol that enforces consistency when synchronization variables are released, a lazy invalidate protocol that enforces consistency when...
