1. GRAM5 - A sustainable, scalable, reliable GRAM service Stuart Martin - UC/ANL

2. SC 2009GRAM52 What is GRAM? l GRAM is a Globus Toolkit component u For Grid job management l GRAM is a unifying remote interface to Resource Managers u Yet preserves local site security/control l GRAM is for stateful job control u Reliable create operation u Asynchronous monitoring and control u Remote credential management u Remote file staging and file cleanup

3. SC 2009GRAM53 Grid Job Management Goals Provide a service to securely: l Create an environment for a job l Stage files to/from environment l Cause execution of job process(es) u Via various local resource managers l Monitor execution l Signal important state changes to client

4. SC 2009GRAM54 Traditional Interaction 4 Local Jobs Resource A Scheduler (e.g., PBS) Compute Nodes l Satisfies many use cases l TACC’s Ranger (62976 cores!) is the Costco of HTC ;-), one stop shopping, why do we need more?

5. SC 2009GRAM555 Local Jobs Resource A GRAM Service Scheduler (e.g., PBS) Compute Nodes remote GRAM Jobs GRAM API l Add remote execution capability u Enable clients/devices to manage jobs with logging into the cluster GRAM Benefit

20. SC 2009GRAM520 Changes Made to Improve Scalability l Removed extra listening port per job for MPIg jobs u Functionality can be re-implemented around GRAM l Removed active monitoring of stdout/err files for streaming during job execution u Instead transfer stdout/err at the end of job execution

21. SC 2009GRAM521 Improvements l New Job Manager Logging implementation l Added job exit code support l Added GRAM service version detection l Added usage statistics support l Added support for auditing of TG gateway user attribute l Updated admin, user, developer guides l Many bugs fixed

22. SC 2009GRAM522 Releases and Testing l 3 Alpha releases and 1 Beta u 2 deployments on TeraGrid l Significant scalability testing of Condor-G u Jaime Frey u Igor Sfiligoi u Gaurang Mehta l Included in GT 5.0.0 RCs l Internal functional and performance testing u http://cvs.globus.org/toolkit/docs/5.0/5.0.0/execution /gram5/qp/#id2557011
