News from the High Performance world, by Dr Laurent Gatineau
(lgatineau at alinka.com)
======================================================================
Software for Beowulf cluster
========
FAI (fully automatic installation) 2.2 released [1]

FAI is  a  non  interactive  system  to  install  a Debian   GNU/Linux
operating system on a PC cluster. You can take one or more virgin PCs,
turn  on the   power  and after  a few   minutes  Linux is  installed,
configured and running  on the whole  cluster, without any interaction
necessary. Thus it's  a scalable method for  installing and updating a
Beowulf cluster  or a network of  workstations unattended  with little
effort involved. FAI uses the  Debian distribution and a collection of
shell and Perl scripts  for the installation  process. Changes  to the
configuration files  of  the operating  system  are made  by cfengine,
shell and Perl scripts.

Tips and tricks from the Beowulf mailing list
========

* Pedro Díaz Jiménez [m1] posted a link [1] to a small FAQ about cluster.
[1] http://planetcluster.org/clusterfaq.html
[m1] http://www.beowulf.org/pipermail/beowulf/2001-September/001265.html

* Marc Cozzi  [m1] is looking  for  using PGI  BLAS routines with  the
  Linpack benchmark.  Eswar Dev [m2] gave  an example using ATLAS BLAS
  library.  Daniel Kidger  [m3] pointed him to  a document showing bad
  performances with the PGI BLAS routines.

[m3] http://www.beowulf.org/pipermail/beowulf/2001-September/001277.html

* About  switches, Eric  Kuhnke [m1] wrote  that he  is happy  with HP
  Procurve  4000M,  but modules  are  expensive (look  how to get them
  cheaper  [m2,m3]).  There was also  a  discussion about SCI networks
  [m4,m5] and Myrinet ones [m6,m7].

[m7] http://www.beowulf.org/pipermail/beowulf/2001-September/001279.html

* Karl Bellve [m1] is looking  for copper based  Gigabit card on Alpha
  system.  Donald  Becker  [m2]  answered that Syskonnect,  Intel  and
  NatSemi  DP83820 network  cards  have drivers   and work with  Alpha
  system.
