data link for April 1999

AAAS Seeks Input: The American Association for the Advancement of Science's website encourages comment and discussion on a document that will provide guidance to the National Science Foundation (NSF) on investments in advanced networking infrastructure support to research. Input via the site, which AAAS hopes will represent the range of perspectives within the academic research community, will be considered by NSF in planning future programs. The comment period ends May 1, 1999. §
Capability Computing Conference and Workshop: NCSA and SGI are hosting a two-day conference in May addressing capability computing on the NCSA Origin2000 system. A two-day workshop (with limited attendance) follows. Register on or before April 16th to attend the conference and/or workshop. §
Summer Research Opportunity Internships Available for 1999: A Summer Research Opportunities Program (SROP), a 6-week internship to interest talented women and undergraduate minority students in the computational sciences, is being sponsored by the Committee on Institutional Cooperation. Review the complete information to decide if you want to participate as an intern or mentor. §
Kentucky's SPP-2200 LSF Job Status and System Load and Memory Usage: Users of the University of Kentucky's Exemplar SPP-2200 have two new pages that succinctly provide important system information. Check on all queues or specific ones. Take a look at the current load and memory usage. §
Is an NCSA HPC System Up?: If you have ever wanted a quick visual way to determine if an NCSA high-performance system is up and running, check out the new systems status page. If the silver "lozenge" is displayed on the green side of the image, your system is up and available. More such tools are in development. §
Scheduling Issues on the Origin2000 in IRIX 6.5: With IRIX 6.5, SGI changed the default scheduling of shared memory applications to dynamic adjustment of threads between parallel regions. In IRIX 6.4, default scheduling of parallel threads used gang scheduling. If you have shared-memory parallel codes, read more about how this change impacts your computational research. §
Performance and Parallelization Study of a CBMC Code: NCSA's Balaji Veeraraghavan recently helped a team from Oklahoma State University port and parallelize their CBMC (Configurational Bias Monte Carlo) code to NCSA's SGI Origin2000. The process Veeraraghavan followed can help you work through a similar port. §
Are You on the Internet Fast Lane?: Find out if you are on the Internet's two fastest lanes: the vBNS and Abilene. With three simple steps, you can determine your network connectivity, discover the routes your data take, and learn how to measure and improve performance. §
Emerge: Emerge is an NCSA effort to develop middleware components of a new distributed search infrastructure that addresses the scale and heterogeneity of scientific data. Emerge components let search services interoperate across scientific domains by providing user-configurable tools for mapping between metadata schemas, performing search queries against multiple data sources, and performing query pre- and post-processing. §
Habanero: In mid-April, NCSA released version 2.0 of Habanero, software that provides a collaborative framework and environment containing applications that let you interact with other on the web (e.g., whiteboard, "clip n ship," local neighborhood, telnet, chat). Written in Java, Habanero runs under any OS that supports Java 1.1.6 or higher. §
Where is the Software?: Keeping track of what software is deployed on which system can be a headache for system administrators and users. A software deployment database being developed by the National High-Performance Software Exchange (NHSE) and teams affiliated with the Globus project are a step closer to solving this problem. §
