• 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.

The Virtual Data Toolkit (VDT) is a set of software, developed by GriPhyN researchers, for constructing the first global petascale virtual grid for data intensive science. The aim is to unify the view of data in a distributed grid environment.

• We use Condor to implement high throughput computing on a large, on-site collection of distributively owned computing resources.

• In order to achieve site to site connectivity, common protocols and security services are applied using Globus.

The Virtual Data Toolkit

• April 2002: we installed the first release of the VDT 1.0

• May 2002: we successfully tested VDT locally

• June 2002: we worked with the VDT team to improve their documentation

• July 2002: we updated to VDT 1.1.2 (development version)

• August 2002: visit to Fermilab and Madison to learn about Globus and Condor-g

• September 2002: we successfully tested Globus on the grid
