In order for collective communication routines to achieve high performance on different platforms, they must be able to adapt to the system architecture and use different algori...
We consider a distributed system where each node keeps a local count for items (similar to elections where nodes are ballot boxes and items are candidates). A top-k query in such ...
Markov random field models provide a robust and unified framework for early vision problems such as stereo, optical flow and image restoration. Inference algorithms based on graph...
This paper is concerned with performance debugging of multitier applications, such as commonly found in servers and dynamic-content web sites. Existing tools and techniques for pr...
Message Passing Interface (MPI) is a widely used standard for managing coarse-grained concurrency on distributed computers. Debugging parallel MPI applications, however, has alway...
