Computing Resources, An Overview

Vinod Gupta

Computing Committee Meeting2006-11-10

Campus wide Computing Resources• Windows:

- Administrative and Business Applications, commercial s/w- Managed centrally from Domain Controllers based on MS Active Directory.- About 100 Org Units (OU), DeSC is the largest with 3000 machines.- PHYSICS OU has 3 sub-OUs: Public, Personal, Research.

• Mac: - Mainly Laptops, a few Desktops.- No servers, no central management.- With h/w migration to Intel h/w and Unix s/w, a larger set of Windows and Public Domain s/w port- Possibility of integration under Windows Domain- May become DeSC machines in future.

• Unix: - New thrust to research computing, major push from Astro, Genomics, EQuad- Traditional mainframes and Unix systems giving way to large clusters – Orangina Blue Gene (IBM PPC), Della (Dell/Intel), Hecate (SGI/Intel)- Largely reserved for a few research groups, rest shared by others for a fee

• Services:- Network backbone- IMAP/SMTP/Exchange, Listserv for Mailing-Lists- TSM Backups- LAMP (Linux+Apache+MySQL+PHP) app dev- Multi-Media, Flash, Fixed Image app dev- Events Calendar- Hardware Support (Dell, Xerox, HP) @ $92/hour

Departmental Computing Resources• Feynman Cluster:

- 250 CPUs, 200 GB RAM and 20 TB disk storage.- Runs RHEL4 linux.- PBS+MAUI based batch management system- Web server hosts personal+group sites exported from feynman http://physics.princeton.edu/it/cluster/

• 26 Public Desktops:- 10x Linux workstations- 8x dual G5 Macs- 8x Windows

• 800 hosts, sharp rise after Host+Port became free• A dozen network printers

http://physics.princeton.edu/it/printing.html • Jadwin Hall now fully equipped with PUWIRELESS and PUVISITOR• Large posters printing and lamination • Mobile Video projection system

Current Capacity

2 Head Nodes (Dual Xeon, 2 GB RAM) 2 Compute Nodes, 2x Xeon, 2GB (Dept) 6 Compute Nodes, 2x AMD, 4GB (Page) 15 Compute Nodes, 2x Xeon, 4GB (Ravin) 50 Compute Nodes, 4x cores, 2GB (Uros)

1.2 TB Disk (Home, Group, Scratch)1.0 TB Disk MiniBOONE3.0 TB Disk BELLE8.5 TB Disk CMS6.0 TB Disk CMB/ACT

Future Directions• No significant changes foreseen for Business

Computing. MSVista and Macs likely in 2008.• CMS starts production in 2007, will need large data

storage, bandwidth, Grid, complex software management. Fermilab will be primary data source for US CMS.

• ACT starts production will start very soon, Princeton will be primary data source for the collaboration.

• Jason Petta joining in Jan 2007, will need significant computing resources.

• Bob Austin is preparing a proposal for significant computing resources.

• PCTP computing needs not very clear at this moment• Ray moved to students lab, process for replacement

initiated. Neel getting stronger every year. Working to maximum of our capacity.
