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 are there or coming– 20,000 sqft of raised floor, new power coming straight from the nuclear
plant, $3c a kwatt– 10 Gbps connection being worked on, NLR 6 miles away from machine
room. ~$1.5M 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

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”

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 2am 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

First submit file attemptMonday noon-ish
• Used the documentation and examples at Wisconsin condor site and created:
Universe = vanillaExecutable = main.exelog = re.logoutput = out.$(Process).outarguments = 1 llllll-0Queue
• Forgot to specify Windows and Intel and also to transfer the output back (thanks David Atkinson)
• Got a single submit file to run 2 specific input files by mid-afternoon TuesdaySlides from Dr. Kurz
Condor Week 2007
Tuesday 6 pm – submitted 1800 jobs in a Cluster
Universe = vanillaExecutable = MainCondor.exerequirements = Arch=="INTEL" && OpSYS=="WINNT51"should_transfer_files = YEStransfer_input_files = InputData/input$(Process).ftwhenToTransferOutput = ON_EXITlog = run_1/re_1.logoutput = run_1/re_1.stdouterror = run_1/re_1.errtransfer_output_remaps = "1.out = run_1/opt1-output$

• 200 ran at a time, but that eventually got resolved

“Currently, we are conducting large bio text mining on the Condor. The Medline database of U.S. National Library of Medicine includes over 17 million citations of life science journals for biomedical articles back to 1950s. Our research focuses on mining relationship between ten thousands genes, chemicals and hundreds of diseases from Medline database. The Condor provides us a platform for the quick, parallel search the Medline database.”

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

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

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 !!
