THE UNIVERSITY OF MELBOURNE Melbourne, Australia ATLAS Tier 2 Site Status Report Marco La Rosa

THE UNIVERSITY OF MELBOURNE Architecture 39 P4 2.4 CPUs (30 x 1GB RAM, 9 x 512MB RAM) Management Node  NFS (home directories, CA certificates), NIS, NAT, Torque and Maui-3.2.6p16 (S. Traylen), Ganglia Compute Element DPM SE (1.7 TB, head node / disk server together 1 unit) R-GMA Mon Node WN MgtCESE Mon.hpc.unimelb.edu.au.unimelb.edu.au Private LAN /24

THE UNIVERSITY OF MELBOURNE Virtual Organisation's ATLAS and BIOMED VOs supported. Fairshare based scheduling. Torque node properties identify which nodes can run ATLAS jobs (those with 1GB RAM) maui.cfg ----snip---- GROUPCFG[atlas]FSTARGET=5PRIORITY=10 GROUPCFG[atlasprd]FSTARGET=100PRIORITY=1000 GROUPCFG[atlassgm]FSTARGET=10PRIORITY=10000 MAXPROC=2 ----snip---- ATLAS: 16,000 jobs, hours, 63.43% BIOMED: 761 jobs, hours, 94.79%

THE UNIVERSITY OF MELBOURNE Networks Need to sustain > 160Mbps from Academia Sinica (.tw) to University of Melbourne (.au) Currently, max throughput: ~90Mbps (iperf) 15 MB/s recently (FTS)...Min Tsai Taiwan to Singapore Limit reached East coast 10Gbps RTT (west): ~140ms RTT (east): ~250ms

THE UNIVERSITY OF MELBOURNE ATLAS Installed Software: VO-atlas-tier-T2 VO-atlas-cloud-TW VO-atlas-release VO-atlas-offline VO-atlas-offline VO-atlas-production VO-atlas-production How much disk space is required for ATLAS software? What is the ATLAS Policy for software removal? Where do I find the results of Athena validation tests? How do I find out what's happening with ATLAS production?

THE UNIVERSITY OF MELBOURNE General Issues Better integration b/w CIC portal and GOCDB  Why do I need to set a scheduled downtime in both?  GOCDB time is out by one hour for Melbourne, Australia timezone (we are in daylight savings ATM).  CIC portal times shown in localtime; auto-converted to UTC? ATLAS users and parallel threaded globus-url-copy (silent re-write or error message informing them of error). ATLAS jobs to upload data from site-SE to elsewhere – why? Job efficiency – at what point can jobs be killed?

THE UNIVERSITY OF MELBOURNE Java and Australian CA Certificates. Root CA cert 4096 bits On the client: /usr/java/j2sdk1.4.2_12/jre/lib/security/java.security security.provider.1=sun.security.provider.Sun security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider security.provider.3=com.sun.net.ssl.internal.ssl.Provider security.provider.4=com.sun.rsajca.Provider security.provider.5=com.sun.crypto.provider.SunJCE security.provider.6=sun.security.jgss.SunProvider Perhaps the Grid can upgrade to Java-1.5? rgmasc SFT, edg-mkgridmap... what else? General Issues

THE UNIVERSITY OF MELBOURNE Funding secured for the next 5 years. Discussions with the University and APAC about support, hosting, contributions (people, CPU, disk). Tentative plan:  minor purchase March '07  major purchase June '07 Looking Forward

THE UNIVERSITY OF MELBOURNE Thankyou Marco La Rosa
