Submissions: Authors should submit an extended abstract electronically, following the guidelines available on the ICTCS Web Page. The extended abstract should start with a title page consisting of the title of the paper; each author's name, affiliation, and email address; and a brief summary of the results to be presented. This should then be followed by a technical exposition of the main ideas and techniques used to achieve the results, including motivation and a clear comparison with related work. The full extended abstract should not exceed 12 single-spaced pages. If more details are needed to substantiate the main claims of the paper, the submission may include a clearly marked appendix that will be read at the discretion of the program committee.

Speakers: * David B. Jackson, Chief Technical Officer, Cluster Resources, Inc. * John Gustafson, Chief Technical Officer, HPC, ClearSpeed Technology Save the date for the next BayBUG: April 24, 2007 Presentation 1 Title: Batch vs. Interactive Scheduling in Clustered Computing Abstract: Mr. Jackson will give an overview of batch v. interactive scheduling in clustered computing. He will discuss how tools can help empower organizations to fully understand, control and optimize their compute resources, focusing on the pros and cons of each approach. In particular, he will address issues of availability and reliability, as well as its ability to scale to larger systems, more complex problems and multiple clusters as well as user friendly design. He will then explore the current landscape of available tools, noting which considerations users must take into account when choosing resource managers and workload schedulers. Because of his deep experience with the Moab Cluster Suite family, he will help users better understand this popular technology. Then he will make a closer examination of how popular tools such as Moab can be optimized for particular cluster architectures, including Beowulf-class clusters. Speaker Bio: David B. Jackson, CTO of Cluster Resources, Inc. David has more than fifteen years of experience in the high performance computing (HPC) industry. He designed and developed the pervasive Maui Scheduler and other open-source resource management software, and has since been the lead architect for cluster, grid and hosting center management suites (Moab Cluster Suite, Moab Grid Suite and Moab Hosting Suite). He has worked for numerous high performance computing centers providing resource management and scheduling services including Lawrence Livermore National Laboratory, San Diego Supercomputer Center, NCSA, PNNL, MHPCC, and the Center for High Performance Computing. David has also worked as a consultant at IBM's AIX System Center. A founding member of the Global Grid Forum scheduling working group and a key member of the Department of Energy's Scalable System Software Initiative, He has a M.S. in Computer Science) and B.S.'s in Electrical and Computer Engineering and in Computer Science from Brigham Young University. Presentation 2 Title: Requirements for Successful Use of Accelerators Abstract: Accelerator boards offer the possibility of increasing performance on highly-specific tasks, while economizing on electric power and space requirements that frequently limit the scale of Linux clusters. We present the full set of issues that must be considered for successful use of such accelerators, including software, precision, compatibility, latency, bandwidth, and memory size. Surprisingly, the applications for which accelerator boards such as those made by ClearSpeed work well also tend to be somewhat insensitive to bandwidth to the host node and highly insensitive to the latency. Speaker Bio: John Gustafson, Chief Technical Officer, HPC, ClearSpeed John joined ClearSpeed in 2005 after leading high-performance computing efforts at Sun Microsystems. He has 32 years experience using and designing compute-intensive systems, including the first matrix algebra accelerator and the first commercial massively-parallel cluster while at Floating Point Systems. His pioneering work on a 1024-processor nCUBE at Sandia National Laboratories created a watershed in parallel computing, for which he received the inaugural Gordon Bell Award. He also has received three R&D 100 Awards for innovative performance models, including the model commonly known as Gustafson's Law or Scaled Speedup. John received his B.S. degree from Caltech and his M.S. and Ph.D. degrees from Iowa State University, all in Applied Mathematics. -- Donald Becker becker@scyld.com Scyld Software Scyld Beowulf cluster systems 914 Bay Ridge Road, Suite 220 www.scyld.com Annapolis MD 21403 410-990-9993 From becker at scyld.com Mon Feb 26 12:25:56 2007 From: becker at scyld.com (Donald Becker) Date: Tue Nov 9 01:14:21 2010 Subject: [Beowulf-announce] Rescheduled BWBUG meeting tomorrow, Feb 27 2007 Message-ID: --- Special Notes: - This is the weather-rescheduled presentation from February 13 - The meeting is at Georgetown University building off Wisconsin Ave. - See http://www.bwbug.org/ for full information and any corrections Baltimore Washington Beowulf User Group Meeting Date: 27 Feb 2007 at 2:30 pm - 5:00pm.

(this is NOT at the main Georgetown U campus. This is an off campus building one block from Wisconsin avenue) Don was the co creator, along with Thomas Sterling, of the Beowulf Project at NASA Goddard. The Beowulf Project is an example of one of the most successful U.S. Government technology transfer projects. In 2007 IDC estimates that the HPC market will exceed 13 billion dollars the majority of which will be cluster technology built on the original Beowulf concept. -- Donald Becker becker@scyld.com Scyld Software Scyld Beowulf cluster systems 914 Bay Ridge Road, Suite 220 www.scyld.com Annapolis MD 21403 410-990-9993
