1. Purdue RP Highlights TeraGrid Round Table May 20, 2010 Preston Smith Manager - HPC Grid Systems Rosen Center for Advanced Computing Purdue University

2. Updates on Purdue Condor Pool Purdue Condor resource now in excess of 30,000 cores Recent active users: –Fixation Tendencies of the H3N2 Influenza Virus –N-body simulations: Planets to Cosmology –De Novo RNA Structures with Experimental Validation –Planet-planet scattering in planetesimal disks –Robetta Gateway TeraGrid Round Table, 5/20/2010

3. New Developments in Condor Pool Virtual Machine “Universe” TeraGrid Round Table, 5/20/2010 Running on student Windows labs today – with VMWare Integrating now: KVM and libVirt on cluster (Steele) nodes

4. Condor VM Use Cases “VMGlide” –Using Condor to submit, transfer, and boot Linux VMs as cluster nodes on Windows systems More usable to the end-user! –Tested and demonstrated on the order of ~800 VMs over a weekend All running real user jobs inside of the VM container –Working with Condor team to minimize the network impact of transferring hundreds of VM images over the network TeraGrid Round Table, 5/20/2010

5. Condor VM use cases User-submitted virtual machines –For example: User has a code written in Visual Basic, that runs for weeks at a time on his PC Submitting to Windows Condor is an option, but the long runtime coupled with an inability to checkpoint limits its utility Solution: –Submit the entire Windows PC as a VM universe job – which will be suspended, checkpointed, and moved to a new machine until execution completes TeraGrid Round Table, 5/20/2010

6. Condor and Power In the economic climate of 2010, Purdue, like many institutions is looking to save power costs The campus Condor grid will help! –By installing Condor on machines around campus we will Get useful computation out of the powered-on machines And if there’s no work to be done? –Condor can hibernate the machines and wake them when there is work waiting TeraGrid Round Table, 5/20/2010

7. Cloud Computing: Wispy Purdue staff operating experimental cloud resource –Built with Nimbus from UC –Current Specs 32 nodes (128 cores): –16 GB RAM –4 cores per node –Public IP space for VM guests TeraGrid Round Table, 5/20/2010

8. The Workspace Service TeraGrid Round Table 5/20/2010 Slide borrowed from Kate Keahey: http://www.cs.wisc.edu/condor/CondorWeek2010/condor-presentations/keahey-nimbus.pdf

9. Wispy – Use Cases Used in Virtual Clusters –Publications using Purdue’s Wispy cited below NEES project exploring using Wispy to provision on- demand clusters for quick turn-around of wide parallel jobs Working with faculty at Marquette Univ. to use Wispy in Fall 2010 course to teach cloud computing concepts With OSG team, using Wispy (and Steele) to run VMs for STAR project TeraGrid Round Table, 5/20/2010 “CloudBLAST: Combining MapReduce and Virtualization on Distributed Resources for Bioinformatics Applications” by A. Matsunaga, M. Tsugawa and J. Fortes. eScience 2008. “Sky Computing”, by K. Keahey, A. Matsunaga, M. Tsugawa, J. Fortes, to appear in IEEE Internet Computing, September 2009

10. HTPC High-Throughput Parallel Computing –With OSG and Wisconsin, using Steele to submit ensembles of single-node parallel jobs Package jobs with a parallel library (MPI, OpenMP, etc) Submit to many OSG sites as well as TG –Who’s using? Chemistry – over 300,000 hours used in Jan –HTPC allowed 9 papers in 10 months to be written! TeraGrid Round Table, 5/20/2010

11. Storage DC-WAN mounted and used at Purdue –Working on Lustre lnet routers to reach compute nodes Distributed Replication Service –Sharing spinning disk to DRS today –Investigating integration with Hadoop Filesystem (HDFS) NEES project investigating using DRS to archive data TeraGrid Round Table, 5/20/2010
