Communication optimizations for fine-grained UPC applications
2005
14th International Conference on Parallel Architectures and Compilation Techniques (PACT'05)
Preserved Fulltext
In this paper we present three optimization techniques for global address space programs with fine-grained communication: redundancy elimination, use of split-phase communication, and communication coalescing ...
By separating the initiation of a remote memory access as far away as possible from its completion, its latency can be hidden through the overlapping of communication and computation as well as message ...
Redundancy elimination may also be used to avoid some of the bookkeeping overhead of a shared address space. • Message coalescing: Coalescing small puts and gets into large messages can be a valuable optimization ...

This paper presents a novel domain-independent method for redundancy elimination from input videos before summarization maintaining keyframes in the original video. ...
The method also gives superior results compared to other state-of-the-art redundancy elimination methods for video summarization. ...
The algorithm works by passing messages between nodes of graph. The nodes are four neighbors of pixel under consideration. Each message has dimension same as number of possible states of flow vector. ...

The error-correction analysis of MCD architecture and the investigation of C-element's robustness are first introduced. ...
Traditionally, there are two versions of the algorithm. When b =(d v −1), all local incoming messages are required to be unanimous, the method is known as the Gallager-A algorithm. ...

The Hikari system does not use node identifiers for message forwarding thus eliminating the complexity of routing associated with many forwarding schemes in DTN. ...
We have shown that Hikari achieves a superior deliver rate while keeping redundant messages in the system low, which is ideal when using devices with limited resources for message dissemination. ...
We consider two features that contribute to eliminate redundancy and loops in the system: Time To Live (TTL): Messages have a TTL counter that represents the lifetime of the message. ...
