1 Condor Project Computer Sciences Department University of Wisconsin-Madison Condor's Use of the Cisco Unified Computing System

2 Condor and UCS › How can UCS benefit a Condor pool  Automated provisioning of machines with specialized configurations › Experimenting with a small UCS system and our local Condor pools  CHTC  BaTLab

3 Center for High- Throughput Computing › Offers free compute resources to any researcher at UW-Madison › Extensive hands-on assistance for researchers › 2000 dedicated cores in CHTC › Many more cores available across campus and in OSG

4 BaTLab › Automated building and testing of software › Dozen of platforms › Used by Condor and many other projects ›

5 Use Cases › Switching OS on a machine  Match resource mix to demand › Jobs that require hardware access  GPUs, hardware counters, VM testing › Jobs that need special network configurations  Sensitive data (HIPPA)  Tests analyzing network traffic

6 Switching OS on a Machine › BaTLab has 1 or 2 machines per platform › Spike in jobs for a platform can cause large backlog › OS-switching machines can help manage backlog

7 Tools We’re Using › Offline ads › Condor rooster › GoUCS › PXE boot › Cobbler › Puppet

8 Execute Machine UCS 8 Execute Machine Submit Machine Machine Startup schedd startd Central Manager collectornegotiator P P J S J rooster cobbler puppet SS PXE S J S P P GoUCS

9 Future Work › Improve offline ads and rooster  Multiple ads represent one machine  Pick most-matched ad to awaken  Shut down machine to switch ads

10 Future Use Case › Jobs that require hardware access  Jobs that use GPUs, hardware counters, VMs  Administrator access required  Jobs may corrupt OS or hardware  Need hardware-level method to stop job and re-image machine

11 Future Use Case › Special Network Configurations  Jobs with sensitive data E.g. HIPPA data Configure machine on secured network  Jobs analyzing network traffic E.g. Three-machine test where Alice and Bob communicate and Eve listens in Configure machines on an isolated network
