4. www.cs.wisc.edu/condor Condor: builds & tests › We believe in nightly builds & tests  Running since early 2000  Runs on every platform  Developers immediately know when something breaks

5. www.cs.wisc.edu/condor Condor: build pool (subset)

6. www.cs.wisc.edu/condor Condor: Many environments › Maintain large pool in CS department  Three platforms  Many diverse applications › Have assisted with many pools world- wide:  You’ve seen many of them today  Commercial  Research  Large & Small

7. www.cs.wisc.edu/condor Question › Can we apply this expertise to building, packaging, and distributing Grid software? › YES  NSF Middleware Initiative (NMI)  Virtual Data Toolkit (VDT)

8. www.cs.wisc.edu/condor What is NMI? › NMI is a software infrastructure for middleware, especially grid › Many groups contribute software to NMI › Building, packaging, and testing is based here in Madison, with Condor Team members

9. www.cs.wisc.edu/condor NMI Builds Sources (CVS) Patching GPT src bundles Build & Test Condor pool (30+ computers) … Build Test Binaries Web Builds distributed with Condor 18 distinct platforms

10. www.cs.wisc.edu/condor Builds benefit from Condor › Fault tolerance  Computer fails—build just runs later › Can use DAGMan for ordered builds › New platform? Just add a computer

11. www.cs.wisc.edu/condor Condor & NMI › NMI infrastructure builds lots of software  Capable of doing nightly builds and tests  Condor is one of these pieces of software  Helps Condor with nightly builds and regular tests › We use Condor to build Condor (via NMI) We eat our own dog food
