The BNL RHIC/ATLAS Computing Facility (RACF) Central Analysis/Reconstruction Server (CAS/CRS) Farm is a large scale computing cluster currently consisting of ~2000 multiprocessor hosts running Scientific Linux. Besides providing for computation, the CAS/CRS systems' local disk drives are used by network distributed data systems such as dCache, ROOTD and XROOTD to store considerable...

TORQUE is a successor of the OpenPBS batch queuing system, available as an Open Source product. Despite the wide spread usage of TORQUE as Job Management System on computational farms and LHC grid installations, this batch system does not support any advanced authentication mechanisms. We show two possibilities, how to redesign the existing source code in order to add Kerberos 5...

The upgrade to Jefferson Lab will require a hardware refresh of the mass storage system in order to handle the higher volume of data from new experiments and simulations. The next generation, higher capactity tape drives are also significantly faster, a fact that has implications for almost all parts of the mass storage system. This talk examines the performance tuning required to make...

I would like to explain a bit about our global filesystem and it's use on PDSF. Also about how this filesystem can be extended to other sites/labs. Our filesystem is GPFS, but the concept can also be extended to Lustre or other cluster filesystems.

Storage Classes attempt to represent storage use cases for a given experiment. It is considered harmfull to match the storage classes to real life storage system especialy if the latter is based on path to get the storage configuration of a file. This presentation aims to define the problematic of Storage Classes, explain one possible solution which is implemented at CCIN2P3 and...

This talk will present the current state of the art of benchmarking at CERN. We will explain our benchmarking procedures, review our latest results and talk about where we are going from here. As part of the results review, we will comment on the current CPU trends and we will talk about the increasingly important power consumption.

This talk will describe some improvements to the monitoring and management of the storage and CPU services in the following areas - use of SMART for disk monitoring - integration of disk server monitoring and storage system management - transmission of Grid job memory requirements to the local workload management
