Subject: IT & Tea Seminar:  Andrew Hanushevsky - The xrootd System

This month's "IT & Tea" Seminar is scheduled for Thursday, June 8, 2006.

Topic: The xrootd System
Speaker: Andrew Hanushevsky

Date: Thursday, June 8, 2006
Time: 3:30 - 5:00 PM
Location: SLAC, Orange Conference Room, Bldg 40
Goodies: Tea and cookies provided


When dealing with the concurrent access from a multitude of clients to petabyte-
scale data repositories, high performance, low latency, fault tolerance, robustn
ess, and scalability are very important issues. This work describes the architec
ture and the choices made in designing the xrootd file access system. The first 
goal of the system was to provide access to over 10^7 files representing several
 petabytes of experimental physics data.

This talk describes the xrootd system and explains how performance was achieved.
 The system is currently used by BaBar at SLAC, IN2P3, INFN, FZK, and RAL. It is
 also used the Star at BNL and Alice at CERN. The xrootd system is included in t
he standard CERN root distribution.

About the Speaker:

Andrew Hanushevsky has worked for SLAC as a systems developer since 1996. Prior 
to this, he worked at Cornell University concentrating on Mass Storage Systems a
nd distributed security. His current main focus is xrootd, as it applies to BaBa
r and the PetaCache project.
