UTB Linux Cluster Lobizon

• Lobizon is 96-node linux cluster
• The master (Lobizon) is connected to the
  internet through a firewall. The 96 nodes
  communicate with the master.
• PI III (812 mhz), Red-Hat 7.1 linux.
• Plan to upgrade to 128 nodes in the near
  future.
• Research in LIGO data analysis (LDAS/LAL),
  grid computing (GriPhyN/iVDGL VDT), and
  numerical relativity (CACTUS).
• UTB becoming a LIGO Tier 2 Center (I2,
  system admin).
• UTB participating in a iVDGL/LIGO testbed
  with UWM, Caltech, MIT and PSU.
• Currently administered by 2 undergraduate
  students, Jose Zamora and Sean Morris. Soon
  helped by a graduate student, Santiago Peña.

Status of the VDT installation on Lobizon

• Jose Zamora and Sean Morris have been recently
  working on installing the VDT on Lobizon with the
  help of Scott Koranda
• VDT-1.0 server and developer packages on the
  master/server.
• VDT-1.0 client package on all nodes.
• The pacman seemed to be working pretty well with
  inactive firewall (no errors), and the local
  installation is being successfully tested!
• Step-by-step procedure on the VDT web site are
  OK, however it would very helpful to have a quick
  reference manual, and a readme. Installation
  manuals for each single packages may be too
  dispersive.
• It would be also very useful to have specific
  examples of configuration files and some test
  programs on the web site.
• We used Python 1.5.2, but it would helpful to
  have the libraries for Python 2.2. on the VDT web
  site.

Using the VDT for Education and Outreach

• We are now planning to write a detailed report to
  the VDT team.
• We hope to help the other Tier 3 Centers with the
  VDT installation.
• However, for E/O purposes we would need a simpler
  version of the VDT, for small clusters
• Step-by-step procedure and quick reference
  manual.
• Examples of working configurations.
• Test Programs.
• Schools and teachers use mostly Windows. What do
  we do here?
• iGOC group at Indiana U. propose to employ one or
  two REUs to work on a simple version of the VDT.
• This and more will be discussed in the E/O
  session.
