  1. Condor Introduction Asia Pacific Grid WorkshopTokyo, JapanOctober 2001

  2. Outline Overview: What is Condor • What does Condor do? • What is Condor good for? • What kind of results can I expect?

  3. The Condor Project (Established ‘85) Distributed High Throughput Computing research performed by a team of ~25 faculty, full time staff and students who: • face software engineering challenges in a distributed UNIX/Linux/NT environment, • are involved in national and international collaborations, • actively interact with academic and commercial users, • maintain and support a large distributed production environment, • and educate and train students. Funding – US Govt. (DoD, DoE, NASA, NSF), AT&T, IBM, INTEL, Microsoft, UW-Madison

  4. What is High-Throughput Computing? • High-performance: CPU cycles/second under ideal circumstances. • “How fast can I run simulation X on this machine?” • High-throughput: CPU cycles/day (week, month, year?) under non-ideal circumstances. • “How many times can I run simulation X in the next month using all available machines?”

  5. What is Condor? • Condor converts collections of distributively owned workstations and dedicated clusters into a distributed high-throughputcomputing (HTC) facility. • Condor uses ClassAd Matchmaking to make sure that everyone is happy. • Fault tolerance provided with checkpointing and other technologies.

  6. The Condor System • Unix and NT • Operational since 1986 • Manages more than 1300 CPUs at UW-Madison • Software available free on the web • More than 150 Condor installations worldwide in academia and industry

  7. Some HTC Challenges • Condor does whatever it takes to run your jobs, even if some machines… • Crash (or are disconnected) • Run out of disk space • Don’t have your software installed • Are frequently needed by others • Are far away & managed by someone else

  8. What is ClassAd Matchmaking? • Condor uses ClassAd Matchmaking to make sure that work gets done within the constraints of both users and owners. • Users (jobs) have constraints: • “I need an Alpha with 256 MB RAM” • Owners (machines) have constraints: • “Only run jobs when I am away from my desk and never run jobs owned by Bob.”

  9. Upgrade to Condor-G A Grid-enabled version of Condor that provides robust job management for Globus. • Robust replacement for globusrun • Provides extensive fault-tolerance • Brings Condor’s job management features to Globus jobs

  10. What Have We Done on the Grid Already? • Example: NUG30 • quadratic assignment problem • 30 facilities, 30 locations • minimize cost of transferring materials between them • posed in 1968 as challenge, long unsolved • but with a good pruning algorithm & high-throughput computing...

  11. NUG30 Solved on the Grid with Condor + Globus Resource simultaneously utilized: • the Origin 2000 (through LSF ) at NCSA. • the Chiba City Linux cluster at Argonne • the SGI Origin 2000 at Argonne. • the main Condor pool at Wisconsin (600 processors) • the Condor pool at Georgia Tech (190 Linux boxes) • the Condor pool at UNM (40 processors) • the Condor pool at Columbia (16 processors) • the Condor pool at Northwestern (12 processors) • the Condor pool at NCSA (65 processors) • the Condor pool at INFN (200 processors)

  12. NUG30 - Solved!!! Sender: goux@dantec.ece.nwu.edu Subject: Re: Let the festivities begin. Hi dear Condor Team, you all have been amazing. NUG30 required 10.9 years of Condor Time. In just seven days ! More stats tomorrow !!! We are off celebrating ! condor rules ! cheers, JP.

  13. The Idea Computing power is everywhere,we try to make it usable by anyone.

  14. Condor Tutorial This Afternoon: Outline • Understanding Condor • Using Condor to manage jobs • Using Condor to manage resources • Condor Architecture and Mechanisms • Condor on the Grid • Flocking • Condor-G • Case Study: Distributed TeraFlop
