Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the 6th Asian Symposium on Progr- ming Languages and Systems (APLAS 2008), which took place in Bangalore, December 9 – December 11, 2008. The symposium was sponsored by the Asian Association for Foundation of Software (AAFS) and the Indian Institute of S- ence. It was held at the Indian Institute of Science, as part of the institute's centenary celebrations, and was co-located with FSTTCS (Foundations of So- ware Technology and Theoretical Computer Science) 2008, organized by the Indian Association for Research in Computer Science (IARCS). In response to the call for papers, 41 full submissions were received. Each submission was reviewed by at least four Program Committee members with the help of external reviewers. The ProgramCommittee meeting was conducted electronically over a 2-week period. After careful discussion, the Program C- mittee selected 20 papers. I would like to sincerely thank all the members of the APLAS 2008 Program Committee for their excellent job, and all the external reviewers for their invaluable contribution. The submission and review process was managed using the EasyChair system. In addition to the 20 contributed papers, the symposium also featured three invitedtalksbyDinoDistefano(QueenMary,UniversityofLondon,UK),Radha Jagadeesan (DePaul University, USA), and Simon Peyton-Jones (Microsoft - search Cambridge, UK). Many people have helped to promote APLAS as a high-quality forum in Asia to serveprogramminglanguageresearchersworldwide.Following a seriesof well-attendedworkshopsthatwereheldinSingapore(2000),Daejeon(2001),and Shanghai (2002), the ?rst ?ve formal symposiums were held in Beijing (2003), Taipei (2004), Tsukuba (2005), Sydney (2006), and Singapore (2007).
Book Synopsis Algorithms for Memory Hierarchies by : Ulrich Meyer
Download or read book Algorithms for Memory Hierarchies written by Ulrich Meyer and published by Springer Science & Business Media. This book was released on 2003-04-07 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algorithms that have to process large data sets have to take into account that the cost of memory access depends on where the data is stored. Traditional algorithm design is based on the von Neumann model where accesses to memory have uniform cost. Actual machines increasingly deviate from this model: while waiting for memory access, nowadays, microprocessors can in principle execute 1000 additions of registers; for hard disk access this factor can reach six orders of magnitude. The 16 coherent chapters in this monograph-like tutorial book introduce and survey algorithmic techniques used to achieve high performance on memory hierarchies; emphasis is placed on methods interesting from a theoretical as well as important from a practical point of view.

Book excerpt: I wish to welcome all of you to the International Symposium on High Perf- mance Computing 2002 (ISHPC2002) and to Kansai Science City, which is not farfromtheancientcapitalsofJapan:NaraandKyoto.ISHPC2002isthefourth in the ISHPC series, which consists, to date, of ISHPC ’97 (Fukuoka, November 1997), ISHPC ’99 (Kyoto, May 1999), and ISHPC2000 (Tokyo, October 2000). The success of these symposia indicates the importance of this area and the strong interest of the research community. With all of the recent drastic changes in HPC technology trends, HPC has had and will continue to have a signi?cant impact on computer science and technology. I am pleased to serve as General Chair at a time when HPC plays a crucial role in the era of the IT (Information Technology) revolution. The objective of this symposium is to exchange the latest research results in software, architecture, and applications in HPC in a more informal and friendly atmosphere. I am delighted that the symposium is, like past successful ISHPCs, comprised of excellent invited talks, panels, workshops, as well as high-quality technical papers on various aspects of HPC. We hope that the symposium will provide an excellent opportunity for lively exchange and discussion about - rections in HPC technologies and all the participants will enjoy not only the symposium but also their stay in Kansai Science City.
Book Synopsis Compiler Reorganization of Shared Data by :
Download or read book Compiler Reorganization of Shared Data written by and published by . This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: False sharing in shared memory multiprocessors is caused by a mismatch between the layout of write shared data in memory and the cross-processor memory reference pattern to it. This mismatch can be eliminated by restructuring the data to match the pattern. We have developed compiler algorithms that do this: they analyze per-process shared data accesses in coarse-grained, explicitly parallel programs, pinpoint the data structures that are susceptible to false sharing, and choose an appropriate transformation to reduce it. The restructured programs execute up to three times faster on a KsR-2 multiprocessor, and have considerably better scalability (better performance with increasing numbers of processors). When compared to programmer efforts to restructure shared data (including the extensively hand-tuned SPLASH and SPLASH2 benchmarks), the compiler-directed approach never did worse, and for most programs did considerably better.

Book Synopsis Analysis of Shared Memory Misses and Reference Patterns by : Jeffrey B. Rothman
Download or read book Analysis of Shared Memory Misses and Reference Patterns written by Jeffrey B. Rothman and published by . This book was released on 1999 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Shared bus computer systems permit the relatively simple and efficient implementation of cache consistency algorithms, but the shared bus is a bottleneck which limits performance. False sharing can be an important source of unnecessary traffic for invalidation-based protocols, elimination of which can provide significant performance improvements. For many multiprocessor workloads, however, most misses are true sharing and cost start misses. Regardless of the cause of cache misses, the largest fraction of bus traffic are words transferred between caches without being accessed, which we refer to as dead sharing. We establish here new methods for characterizing cache block reference patterns, and we measure how these patterns change with variation in workload and block size. Our results show that 42 percent of 64-byte cache blocks are invalidated before more than one word has been read from the block and that 58 percent of blocks that have been modified only have a single word modified before an invalidation to the block occurs. Approximately 50 percent of blocks written and subsequently read by other caches shown no use of the newly written information before the block is again invalidated. In addition to our general analysis of reference patterns, we also present a detailed analysis of false sharing and dead sharing in each shared memory multiprocessor program studied. We find that the worst 10 blocks from each our traces contribute almost 50 percent of the false sharing misses and almost 20 percent of the true sharing misses (on average). A relatively simple restructuring of four of our workloads based on analysis of these 10 worst blocks leads to a 21 percent reduction in overall misses and a 15 percent reduction in execution time. Permitting the block size to vary (as could be accomplished with a sector cache) shows that bus traffic can be reduced by 88 percent (for 64-byte blocks) while also decreasing the miss ratio by 35 percent."
