  1. Grid-enabling UTB cluster Manuela Campanelli Sean Morris & Jose’ Zamora The University of Texas at Brownsville LSC Member Institution (UT Brownsville)

  2. 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. Internet Router Warp.utb.edu (Firewall router) Lobizon.utb.edu (Server / Master) Matrix Switch DHCP/Image server 96 node cluster (1-24), (1-24) and (1-24), (1-24) Intel Pentium III, 812mhz, 512 RAM, 40Gb LSC Member Institution (UT Brownsville)

  3. 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.

  4. 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.
