CSIT is sponsoring a series of presentations about the IBM pSeries 690
supercomputers, open to all interested people.
The speaker is Charles Grassl, of
IBM Research.
Talks will be held on the mornings of October 14th through the 16th.
In the afternoon, Charles Grassl has volunteered to spend special help
sessions with individual research groups and other users of the system.
These presentations are only offered once a year. In the past, participants at all levels have found them very helpful in explaining such issues as
Here's the tentative schedule. You are welcome to come to any of the morning talks that interest you. Some of the afternoon help sessions will remain wide-open, while others will be dedicated, on request, to particular research groups. The list of topics is approximately correct for each day, but the hourly listings should not be taken too seriously.

Room 499 is the CSIT Seminar Room. Room 416 is the CSIT Conference Room, which is near the Seminar Room, just around the corner from the kitchen and social area. Room 401 is the "Executive Conference Room", which is very close to the CSIT Reception area.
For an overview of the material, look at the online agenda page: ibm_agenda.html for a rough outline of what will be covered. The actual order and dept of presentation of topics may vary from this typical agenda.
Admission to this presentation is open to all. We would appreciate hearing from each person who is interested in attending, so that we can prepare refreshments, handouts and so on. You are welcome to suggest special topics you'd like to see covered. You may also request that your research group be allocated one of the afternoon help session times.
Charles Grassl, of IBM Research, will conduct the presentation. He is currently an Information Technology Specialist at IBM Research, working on high performance computing issues which involve performance and programming models. His focus includes giving workshops on programming, program conversion, optimization, and the high performance features of the IBM pSeries computers.
He received a PhD in Physics from the University of Wisconsin, and worked in the Benchmarking and Strategic Marketing Groups at Cray Research before joining IBM in 1999.
Mr Grassl has set up an account on Eclipse, where he has placed copies of his presentation notes, program examples, useful tools, and PDF versions of various IBM documents. Users with accounts on the Eclipse can easily browse through these directories. The main directory is
/u/guest/cgrassl/Workshop
which includes the subdirectories
/Examples /Presentations /Tools /docs
The Examples directory includes subdirectories devoted to C, Fortran, General, IO, Libraries, MPI, OpenMP, Opt, Standard_Benchmarks, Tester, Tools, and XLF.
The docs directory includes subdirectories with documentation on AIX, Architecture, Compilers, Debuggers, ESSL, LoadLeveler, MASS, MPI, OpenMP, and User_Guides.
To see any of these documents online, go to the online documents page ibm_documents.html.
CSIT, the school for Computational Science and Information Technology, is an interdisciplinary institute for computational science, providing undergraduate and graduate courses, and research-level computational resources, which include the two IBM pSeries 960 systems, named Teragold and Eclipse, as well as a variety of clustered computers and a visualization lab. For more information, see the CSIT web site at http://www.csit.fsu.edu.
You might wish to examine a list of current research projects, which includes extensive writeups and links.
The CSIT computer named Teragold is a Power3-based IBM pSeries 690 supercomputer. Teragold is used by researchers to convert existing programs to parallel form and to measure the efficiency of such programs. Teragold comprises 162 processors. A user program that runs in parallel can command a large number of these processors at one time, from as few as 4 to as many as 160. Parallel programs are usually written using MPI, OpenMP, or Posix PThreads. Once a program has been shown to perform well in parallel, a researcher may request an account on Eclipse for production runs.
A request for an account on the Teragold may be made by any FSU faculty member or supervised graduate student, in pursuit of a given research topic. The application process is described on the Teragold Account Policy Web Page.
The CSIT computer named Eclipse is a Power4-based IBM pSeries 690 supercomputer. Eclipse serves as the "production" machine, running massively parallel jobs on many processors. Eclipse comprises 512 individual processors, grouped into 16 nodes of 32 processors each. Parallel programs are usually written in MPI, OpenMP, or Posix PThreads. Access to Eclipse is more strictly controlled. An application requires accompanying documentation that the user's program has demonstrated good parallel performance.
