FIU Tier-3 Center Tier-3 Centers in the CMS computing model –Primarily employed in support of local CMS physics community –But some also participate in CMS production activities Hardware & manpower requirement non-trivial Requires sufficient hardware to make worthwhile Grid enabled gatekeeper and other grid services are also required The FIU Tier-3 is deployed to: –Provides services and resources for local physicists CMS analysis, & computing Education Research and Outreach Group –Cyberinfrastructure: serves as a “reference implementation” of an operational grid-enabled resource for the FIU CI community at large FIU Grid community CHEPREO Computer Science groups
FIU Tier-3 at A Glance GATE KEEPER ROCKS based meta-cluster consists of: –Grid-enabled computing cluster Approx: 20 Dual Xeon boxes –Service nodes User login node, frontend, webservers, frontier/squid server, development… –Local CMS interactive analysis Purchased with FIU startup funds A single 8 core server with 16GB RAM A large 3ware based 16 TB fileserver A Computing Element site on the OSG production Grid –A production CE even before the OSG (Grid3) –Supports all of the OSG VOs –Maintained with latest vers of OSG software cache
FIU Tier-3 Usage at Glance Current usage: Since Nov. 2007 –About 40K hrs logged through OSG Grid gatekeeper CMS, LIGO, nanhub, OSGedu… VOs have used the site through this period –About 85% of that was utilized by cmsProd during CSA07 We generated about 60K events out of the 60M world wide effort We were one of 2 or 3 Tier-3s that participated in CSA07 world wide effort !
Tier3 Team at FIU CHEPREO/CIARA funded positions –Micha Niskin: Lead systems administrator –Ernesto Rubi: Networking CHEPREO undergraduate fellows: Working on deploying CMS and storage services –Ramona Valenzula –David Puldon –Ricardo Leante
Tier-3 Computing Facility In support of the Open Science Grid –Still plan to involve our group with OSG integration and validation activities Participate in integration testbed Help carryout testing of new OSG releases Help debug and troubleshoot new grid middleware deployments and applications –This work is currently man-power limited Our systems administrator is busy with new hardware deployments, and procurement and training new CHEPREO fellows In support of CMS computing: production activities –Not yet involved in CCRC08 or CSA08: –Will require new workernodes with 1.0+ GB of RAM/core to participate 10 new dual quadcore nodes + new gatekeeper Specs have been defined bids will be submitted Expect quotes by end of March –Will require additional services for CMS production Storage Element:We evenutually plan to deploy our own dcache based SE but now pointing our cmssoft installation to our local Tier-2 at UF FRONTIER/squid now a must for participation: use existing Xeon hardware, CHEPREO fellows now working on this task
Tier-3 Computing Facility In support of local CMS interactive analysis activities: Issue: How to access CMS data from FIU, several solutions being investigated. They involve close coordination with our CHEPREO Tier-2 partners at UF and Caltech 1.Download data to a Tier-2 and then download to FIU via FDT Deployment, utilization and benchmarking of FDT tool within CMS’ Distributed Data Management system 2.With UF, download data to WAN enabled LUSTER filesystem Tests already demonstrated line speed access with LUSTER over LAN at UF between UF’s Tier-2 and HPC Testing underway on isolated testbed now with UF’s HPC group –Applied kernel patches and reconfiguring network route to FIU test server –pecial Access to HPC facility, unlikely general CMS wide solution 3.L-store: Access CMS data stored in L-store depots in Tennessee region and beyond Vanderbilt is working on L-store/CMSSW integration and we would like to help in the testing when available We would also like to deploy our own L-store depot on-site with Vanderbilt supplied hardware currently at FIU
