We propose repair pipelining , a technique that speeds up the performance in general erasure-coded storage. By carefully scheduling of failed data small-size units across storage nodes pipelined manner, reduces single-block time to approximately same as normal read for single block homogeneous environments. further design different extensions algorithms heterogeneous environments and multi-bloc...

1 Dept. of Computer Science, The William Paterson University of New Jersey, Wayne, NJ 07470, USA 2 Wireless Speech and Data Processing, Nortel Networks, Montreal, QC, Canada, H3E 1H6 Abstract Software pipelining is a loop optimization technique that has been widely implemented in modern optimizing compilers. In order to fully utilize the instruction level parallelism of the recent VLIW DSP proc...

Pipelining is used in almost all recent processor architectures to increase the performance. It is, however, difficult to achieve the theoretical speedup of pipelining, because code dependencies cause delays in execution. Processor designers must use complex techniques like forwarding, register renaming and branch prediction to reduce the loss of performance due to this problem. In this paper w...

Software pipelining has become a very extended loop execution model since microprocessors include more functional units. Scheduling techniques developed for software pipeline a loop have to look for heuristics, thus they achieve the optimal scheduling only in some cases. In this paper we present another software pipelining approach based on a methodology that divides the scheduling problem in t...

Loop pipelining is an important optimization in high-level synthesis (HLS) because it allows successive loop iterations to be overlapped during execution. While current HLS pipelining approach achieves high performance for loops with regular and statically analyzable program patterns, it remains challenging to pipeline loops with irregular memory accesses, irregular dependence patterns, and unb...

Application of wireless sensor network (WSN) for structural health monitoring (SHM), is becoming widespread due to its implementation ease and economic advantage over traditional sensor networks. Beside advantages that have made wireless network preferable, there are some concerns regarding their performance in some applications. In long-span Bridge monitoring the need to transfer data over lon...

The breakthrough of pipelined microprocessors has brought about a need to teach instruction pipelining in electrical and computer engineering curricula at the undergraduate level to a considerable depth. Although the idea of pipelining is conceptually simple, students often find pipelining difficult to visualize. Only the most talented students assimilate the ideas of how hazard issues are elim...

Wave pipelining offers a unique combination of high speed, low latency, and moderate power consumption. The construction of wave pipelines is benefited by the use of gates and buffers with data-independent delays and the knowledge of the interconnection delays. These two features are present in several SRAM-based field programmable gate arrays (FPGA’s): look-up tables (LUT’s) allow the designer...
