                                Eric Moore
                            Computing Clusters

   Computing clusters. Harnessing the power of multiple computers to do
   lots of work. This Tuesday, 15 May Dr. Eric Moore will present on the
   usability, reliability, computational might of connecting various
   hardware to form a single computational entity. A cluster of computers.

   You might wonder, doesn't, didn't virtualization render clustering
   obsolete? expensive, unreliable by comparison? ``Making one PC look
   like many is not the same as making many look like one.  Virtualization
   is for when your iron has more horsepower than needed to do one thing,
   so you want it doing many things.  Clustering (at least the sort Eric
   will discuss) is for when too much horsepower is not enough (and in
   his world, too many flops is never enough, such is life in a field where
   O(N^4) algorithms are considered fast, and run times are often measured
   in weeks),''says Eric.

   Does Linux lead in clustering? Doesn't *BSD rockit harder? ``Yes, no.''

   Should you get Slackware, or Ubuntu, or that little book that tells
   you how to roll your own Linux?

   ``Depends on what you're trying to do.'' Eric will share his experience
   and astutely guide your options.

   Clustering is basically the art of harnessing together many computers
   to do computations that can't be done by one (or in many cases, to
   conveniently do a bunch of computations that can be done on one all at
   the same time).  (There are also high-availability clusters, which will
   be discussed only peripherally). Clusters are found in all sorts of
   places, from Google, which uses them to build its search indexes, to
   the giant render farms that give us animated movies, to the Beowulf
   clusters of scientific research (and their Ghettowulf cousins which
   Eric has mostly built).  If it takes more than a couple hours for your
   program to run, you may want a cluster for that.

   The talk will cover a number of questions regarding:

   * Can you use a cluster for my problem?
   * Should you?
   * What sort of cluster?
   * What tools are there for your kind of problem?
   * What are the trade-offs you need to look at, and what works in what
   * What are your options?
   * Who uses these things, and for what?

   Clustering is a really big field, and covers a lot of ground, and
   there's a lot of really good stuff for doing it under Linux, come hear
   about a whole bunch of these things.

   If you need a cluster, think you need a cluster (or think you don't 
   need one and want to make sure), or just have a bunch of PC's you want
   to turn into a cluster just because, you just might learn something.

   It never hurts to come to a talk about an area where Linux and Free
   Software are the undisputed masters of the field.

   RSVP your place at the marvelous Google lair for this Tuesday, 15 May
   NYLUG meeting. Many thanks to Google for their kind hospitality in
   hosting our group.

 About Eric Moore:
   Eric's a computational chemist, who has had to set up and maintain
   several clusters in his career, and has learned most of the ways not
   to do it, and some things to do.  Right now he teaches for a living,
   but would rather be crunching numbers.  Giving a talk about
   crunching numbers is almost as good.  

 Meeting Location
   Please note that this meeting will be held at Google, 76 9th Ave,
   4th floor, between 15th and 16th Streets, and not at IBM. This is
   the old Port Authority Building, and takes up the entire block.
   You want the entrance nearest 16th Ave.


 Free Refreshments!
   Google is also graciously providing refreshments during the
   meeting. For those of us here in the east who aren't used to a
   "Google spread", you're in for quite a treat. "New Google
   Cafeteria Crushes Competitors" Cafeterias" (New York Magazine)

   Our friends at Prentice-Hall kindly provide us with review copies
   of various new titles.  One of these could be yours, all you have
   to do is agree to review the book within a reasonable period of

 Swag (Give Away)
   During/after the meeting... unusually terrific swag may be given

   After the meeting ... Many of us have been meeting over at the
   Hog Pit starting around 8:15-8:30.
