7:30 PM Presentation "CCNUMA architectures for Unix" by Randy Isbell, Sequent Computer


"CCNUMA architectures for Unix" by Randy Isbell, Sequent Computer

This month's presenter is Randy Isbell a Sr. System Engineer from Sequent Computer's Dallas office. Randy will be discussing CCNUMA architectures for Unix, including information on what CC Numa is, and what problems are appropriate for CC Numa.

CC Numa, which stands for cache coherent non-uniform memory architecture is a type of clustering where large numbers of relatively inexpensive processors are tied together typically through some type of switching fabric. Unlike traditional SMP boxes, these boards do not share a common pool of memory. CC Numa looks like it may become a common architecture in the Unix and NT worlds. Come to the meeting and find out why...


"Libraries, Include Files, and Shared Objects" by Rich Seibel

Rich will discuss a topic of interest to all UNIX developers (and often to users) that was suggested in February.

Special Interest Groups (SIGS)

As our membership grows, we have had some inquiries about the possibility of having Special Interest Groups in several areas. If you are interested in starting or participating in a SIG for System Administration, Networking, C, Object Oriented Programming, a specific vendor, etc., please call Dave Mills at 230-5151, extension 103, or contact any officer of the group.

St. Louis Unix Users Group - Linux SIG (SLUUGLS)

RCS (Revision Control System) by Sanjiv Bhatia

There are plenty of problems in terms of code and documentation management during the life cycle of a project. The major problems in the project occur in keeping track of the changes made to the files. These changes can be managed and tracked by using the RCS utility that is available under the Gnu license. In this presentation, we'll discuss the features of RCS and contrast them with SCCS (the source code control system).

Sanjiv Bhatia is an Assistant Professor of Computer Science at the University of Missouri -- St. Louis. He got interested in RCS to manage some large software projects for his research in image databases.

Do you really know your SLUUG?

by Rich Seibel

You think SLUUG just provides the best source of UNIX information in St. Louis?

You think SLUUG members are just computer jocks?

But, that is not all there is to SLUUG. The SLUUG is investigating new avenues to expand its service to the community.

Stay tuned...

Two USENIX Workshops on NT

by Cynthia Deno


WEB PAGE: or CALL USENIX at (714)588-8649

             August 11-13, 1997
             Seattle, Washington, Sheraton Hotel
             Sponsored by the USENIX Association

WHO SHOULD ATTEND: Researchers in any field of computer science using or adopting Windows NT as their research base.

The USENIX NT Workshop will provide a forum to share information, experiences, and results. An increasing amount of research work is being done on Windows NT, now there is a forum where researchers can gather and learn from each other's work. The workshop includes technical presentations of submitted position papers, invited talks, Birds-of-a-Feather sessions for highly-interactive, focused discussions, demonstrations, and a poster session.

             August 14-16, 1997
             Seattle, Washington, Sheraton Hotel
             Sponsored by the USENIX Association and
             SAGE, the Systems Administrators Guild

WHO SHOULD ATTEND: System managers involved in the management of large-scale Windows NT networks. System administrators as they move either from UNIX to Windows NT or between the two will find it especially helpful.

System administrators are faced with the deployment of Windows NT across complex networks comprised of hundreds of individual Windows NT systems. They are expected to maintain these systems with the same quality of service they deliver for their better-understood UNIX systems and, often, to provide integration services between legacy platforms and Windows NT as well. In this workshop, you will learn about experiences of system administrators who have wrestled with real-life problems and are building solutions today which will scale into tomorrow. There will be lots of opportunities for interaction: during panels, a Work-In-Progress Session, and luncheons. You will discuss topics such as large scale administration, integration, tools, and security. This is an exciting experience for anyone involved in the management of large Windows NT installations.

FREE TO ALL ATTENDEES: Windows NT in a Nutshell - A Desktop Quick Reference for System Administration by Eric Pearce, with Beverly Scherf and Chris Reilly, published by O'Reilly & Associates.

St. Louis Chapter, ACM

The Saint Louis Chapter of the Association for Computing Machinery (ACM) invites you to a discussion of Productivity Gains or Lack of Gains from Information Technology led by Dayle Majors.

        Monday, July 14th, 1997
        Social & Dinner: 6:00 PM. Program: 6:15 - 7:45 PM
        Grones Cafeteria:  4409 Woodson Rd, 423-7880

Summary: Computers and Information Technology have been touted as a significant improvement. However, recent popular media has voiced questions about whether there have been any gains from Information Technology. Economists are having difficulty quantifying gains. Is this a problem with the current methodologies, or has there been no gain? Come and participate in the discussion. Let your opinions be heard.

This will be an open discussion. Since most of us receive our income directly or indirectly from data processing and information technology we should all have an interest.

Discussion Leader: Mr. Majors has been an active participant in Information Technology since the early 1960s. He will not be making a presentation but will facilitate the discussion.

Arrangements: Begin the cafeteria style dinner and social when you arrive. Dinner and FREE lecture are in the back room. Non-members are welcome. No registration. Bring a friend!
