Windows Condor Pool at Clemson University Sebastien Goasguen

Windows Condor Pool at Clemson University Sebastien Goasguen School of Computing and Clemson Computing Information Technology (CCIT) May 2 nd 2007 Condor Week 2007

Clemson basics • Public land grant institution founded in 1889 • ~13, 000 undergrads and ~4, 500 grads • ~1, 300 faculty members New commitment to computing as the backbone of research and teaching Condor Week 2007

Clemson Computing DNA • Clemson has put computing at the core of its mission – New CIO: Jim Bottum – New CTO: Jim Pepin – New School of Computing, search in progress for a school director, three division leaders and couple months later six assistant professors • Building traditional HPC from scratch – No prior involvement in HPC support – No trained staff for either system administration or application • Infrastructure and hardware there or coming – 20, 000 sqft of raised floor, new power coming straight from the nuclear plant, $3 c a kwatt – 10 Gbps connection being worked on, NLR 6 miles away from machine room. ~$1. 5 M SCLR approved by board of trustees last week – Above 10 Tflops in the works through various sources. Automotive research center (Michelin, BMW…), Faculty community cluster and Provost support • All hands on deck to build the CI campus of tomorrow Condor Week 2007

Building CI at Clemson • The Fabric layer – HPC resources ->Clusters – Campus Grid -> Condor – Sharing of resources ->OSG • The middleware layer – Deploy services interface to our resources -> WS – Increase identity management capabilities for sharing -> Gridshib • The application layer – New environments for students – New environments for researchers • ->”Portal”, “Gateways”, Desktop applications, other… • A social layer – Raising awareness on campus – Fulfilling expectations of faculty Condor Week 2007

Teaching CI Condor Week 2007

Where to start ? • No HPC resources • No expertise in HPC or grids • “what works, is reliable and free ? …” • “Let’s do a windows condor pool, and let’s join OSG” Condor Week 2007

Randy Martin, David Atkinson, Matt Rector Condor Week 2007

Results • • • Built a ~1, 000 machines pool and got usage in 4 months Learned condor installation, administration, debugging Experience improved our management of the windows machines – More efficient lab image distribution. The current in-house developed method of distribution takes days to distribute image changes to all pcs…Also need to specify machine ads on image. – Eliminate need for 2 am image refreshes on each lab pc. • Outreach to the whole campus • Got familiar with grid software and operation, used VDT • Attending Condor week. Condor Week 2007

Details • 1085 windows machines, 2 linux machines (central and a OSG gatekeeper), condor reporting 1563 slots • 845 maintained by CCIT • 241 from other campus depts • >50 locations • From 1 to 112 machines in one location • Student housing, labs, library, coffee shop • Mary Beth Kurz, first condor user at Clemson: • March 215, 000 hours, ~110, 000 jobs • April 110, 000 hours, ~44, 000 jobs Condor Week 2007

The world before Condor • • 1800 input files 3 alternative genetic algorithm designs 50 replicates desired Estimated running time on 3. 2 GHz machine with 1 GB RAM: 241 days Slides from Dr. Kurz Condor Week 2007

First submit file attempt Monday noon-ish • Used the documentation and examples at Wisconsin condor site and created: Universe = vanilla Executable = main. exe log = re. log output = out. $(Process). out arguments = 1 llllll-0 Queue • Forgot to specify Windows and Intel and also to transfer the output back (thanks David Atkinson) • Got a single submit file to run 2 specific input files by mid-afternoon Tuesday Slides from Dr. Kurz Condor Week 2007

Tuesday 6 pm – submitted 1800 jobs in a Cluster Universe = vanilla Executable = Main. Condor. exe requirements = Arch=="INTEL" && Op. SYS=="WINNT 51" should_transfer_files = YES transfer_input_files = Input. Data/input$(Process). ft when. To. Transfer. Output = ON_EXIT log = run_1/re_1. log output = run_1/re_1. stdout error = run_1/re_1. err transfer_output_remaps = "1. out = run_1/opt 1 -output$(Process). out" arguments = 1 input$(Process) queue 1800 • 200 ran at a time, but that eventually got resolved Slides from Dr. Kurz Condor Week 2007

Wednesday afternoon: Love notes Slides from Dr. Kurz Condor Week 2007

Type of jobs being worked on GROMACS, Java universe molecular Text mining “Currently, we are conducting large bio text for dynamics mining on the Condor. The Medline database medline database of U.

Open Science Grid Join the national infrastructure Use the national infrastructure Contribute resources (hardware and human) Ease of installation through VDT Condor Week 2007

Firewall Issues • Couple years ago after Blaster and Co, Clemson put every machine behind a firewall. • Globus ephemeral ports closed – Cannot send Globus job from my desktop osggate Condor-c ssh desktop Condor Week 2007

Next-generation: Socially immersive science gateways Work being led by Prof. Madhavan with CCIT collaboration Condor Week 2007

Conclusions • • • Clemson has made computing a priority Condor is the first “CI” project at Clemson OSG is a close second Condor has already impacted Clemson researcher Clemson hopes to contribute to the community NSF seems happy… • Thanks to the Condor team !! • Acknowledgements: Randy Martin, David Atkinson, Matt Rector, Mike Gossett, John Minor, Matt Saltzmann, Mary.
