Today is the day for the next Seattle Sage Group meeting.

The Seattle SAGE Group (SSG) is a local group for systems & network
administrators in the Seattle and Pacific northwest areas (North
Western Washington). We are a local chapter of SAGE, but SAGE / USENIX
membership is not a requirement.  We sponsor a regular monthly meeting
open to the public on the second Thursday if each month at 7 p.m.

This is a reminder & announcement of the next meeting.


Next meeting: Thursday June 11, 7:00 PM
       Topic: "An Overview of the MOSIX Multicomputer
              System for Cluster Computing
              (aka And don't spare the whip!)"
   Presenter: Prof. Amnon Barak
              Institute of Computer Science
              The Hebrew University of Jerusalem
    Location: Department of Molecular Biotechnology
              University of Washington
              K-Wing room K350 (3rd floor conference room)

Presentation details:

An Overview of the MOSIX Multicomputer System for Cluster Computing

                          Prof. Amnon Barak
                    Institute of Computer Science
                  The Hebrew University of Jerusalem
                       Jerusalem 91904, Israel

Scalable Computing Clusters  (SCC)  are  becoming an alternative to
supercomputers and  MPP's for the execution of high performance,
demanding applications in multi-user, time-sharing environments. In
order to better utilize the multiple resources of SCC's it is
necessary to develop means for cluster wide resource allocation and
sharing, that will make an SCC easy to program and use.

The MOSIX operating system is an enhancement of UNIX with on-line
algorithms for adaptive, cluster wide resource sharing. These
algorithms are  geared for performance scalability using a preemptive
process migration for load-balancing and memory-sharing in order to
create a convenient time-sharing execution environment for HPC,
particularly for applications that are written in PVM and MPI.

The talk gives an overview of MOSIX and its resource sharing
algorithms. The talk then presents our experience with the execution
of several large-scale parallel applications,   including Protein
sequences, molecular and quantum dynamics simulations.


This is FREE and open to the public and a wonderful opportunity.

NOTE: The K-Wing (and most of the UW) is locked up tight at ~6:30. We
send someone down every 10 min or so to the SOUTH side entrance (the
one just next to the bike rack and parking attendant booth on the bay
side of the building). Also, from the meeting room we can look down on
that very doorway & part of the covered bench to see if someone is
waiting there. We generally keep checking every 10 minutes or so
through 7:45. Since the bench area with the bike racks just outside
the door is covered you may remain dry on a rainy evening. Hence, if
you stand close the building by the bench under the roof you will be
dry and visible to us from the meeting room. We also sometimes call
down to see if someone standing there is waiting for SAGE. So, you may
hear a voice from above inquiring about SAGE, don't be too alarmed....

Of course the best solution is to get here about 6:50 along with the
majority of others.
