  2. Workflow • The computerized facilitation or automation of a business process, in whole or part. • WiT = ( GrT, GsT, QuT, WmT ) • Wi = Workflow instantiation • Gr = Grid resources • Gs = Grid services • Qu = Quality expectations from the user • Wm = Workflow model. von Laszewski, G. (2006). Java CoG Kit Workflow Concepts. Journal of Grid Computing. http://grid.rit.edu

  3. Condor • High throughput computing system • Job management • Scheduling policy • Priority scheme • Resource monitoring / management • Checkpointing • Fault tolerance • Migration http://grid.rit.edu

  4. Condor • Kernel architecture Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  5. Condor • Job submission in a condor pool Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  6. Condor • Gateway flocking Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  7. Condor-G • Interacting with GRAM • Disadvantage – the agent does not know which resource is available in the foreign system Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  8. Condor – Gliding In • Step 1 – submit Condor servers as jobs Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  9. Condor – Gliding In • Step 2 – submitted servers form an ad-hoc Condor pool with the matchmaker Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  10. Condor – Gliding In • Step 3 – use the Condor pool as normal Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  11. Condor - Problem Solvers • Master-Worker • Master process assigns jobs to worker processes • Suitable for a large problem with no dependency • DAGMan (The Directed Acyclic Graph Manager) • For multiple jobs with dependancy A Directed Acyclic Graph Thain, D., Tannenbaum, T., & Livny, M. (2005). Distributed computing in practice: the Condor experience. Concurrency - Practice and Experience, 17(2-4), 323-356. http://grid.rit.edu

  12. Condor Universes • Define execution environments • Standard (default) : checkpointing & remote system calls • Vanila : run programs which cannot be re-linked • PVM : run Parallel Virtual Machine programs • MPI : run MPICH programs • Globus : use a Globus system • Java : run on JVM • Scheduler : executes jobs without waiting to be matched to resources. Used for DAGMan http://grid.rit.edu

  13. Condor • Example submit description file • submit.hello Executable = hello Universe = standard Output = hello.out Log = hello.log Queue • To submit the job • > condor_submitsubmit.hello http://grid.rit.edu

  14. Globus GRAM • Grid Resource Allocation and Management • Program execution requirements • State • User executables • Staging of input and output • Streaming output • Control • Scheduler • Monitoring http://grid.rit.edu

  15. Globus GRAM • State transition diagram for GRAM jobs Foster, I. (2005). A Globus Primer: Describing Globus Toolkit 4. http://grid.rit.edu

  16. Globus GRAM • Client APIs • Four portTypes: Managed Job Factory, Managed Job, Delegation Factory, Delegation operations interfaces resources Foster, I. (2005). A Globus Primer: Describing Globus Toolkit 4 http://grid.rit.edu

  17. Globus GRAM • GT4 Container • Hosts Web Services Foster, I. (2005). A Globus Primer: Describing Globus Toolkit 4 http://grid.rit.edu

  18. Globus GRAM • GRAM implementation structure Foster, I. (2005). A Globus Primer: Describing Globus Toolkit 4 http://grid.rit.edu

  19. Globus GRAM • Job submission % globusrun-ws -submit -job-command /bin/program arg Submitting job…Done Job ID: uuid:c51fe35a-4fa3-11d9-9cfc-000874404099 Termination time: 12/17/2004 20:47 GMT Current job state: Active Current job state: CleanUp Current job state: Done Destroying job...Done. Foster, I. (2005). A Globus Primer: Describing Globus Toolkit 4 http://grid.rit.edu

  20. Globus GRAM • Job submission with job description files % globusrun-ws -submit -job-description-file touch.xml -factory-epr-file gram.epr #touch.xml <job> <executable>/bin/program</executable> <argument>arg</argument> </job> #gram.epr <factoryEndpointxmlns:gram="http://www.globus.org/namespaces/2004/10/gram/job" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/03/addressing"> <wsa:Address> https://viz-login.isi.edu:9000/wsrf/services/ManagedJobFactoryService </wsa:Address> <wsa:ReferenceProperties> <gram:ResourceID>PBS</gram:ResourceID> </wsa:ReferenceProperties> </factoryEndpoint> Foster, I. (2005). A Globus Primer: Describing Globus Toolkit 4 http://grid.rit.edu

  21. Java CoG Kit • Java Commodity Grid Toolkit • Maps Grid functionality into a commodity framework (Java) • Extends the use of Globus • Purpose • To use Grid services more efficiently by using / developing Java classes http://grid.rit.edu

  22. Java CoG Kit • Workflow management layer • It supports multiple Grid middleware Application Nano Materials, Bio-Informatics, etc. Workflow monitoring Workflow Portlet & visualizer/Editor Task & workflow management Karajan (GridAnt, ant) Job submission file transfer & authentication Workflow Abstractions, Queue/Set Abstractions Grid Middleware + CoG Kit providers GT2, SSH, GT4 WS-RF, WebDAV http://grid.rit.edu
