1 SUN GRID ENGINE & SGE/EE: A CLOSER LOOK Carlo Nardone HPC Consultant Sun Microsystems, GSO SUN GRID ENGINE & SGE/EE: A CLOSER LOOK

2 Agenda Sun and Grid Computing Sun Grid Engine: Architecture Campus Grid Model: Sun Grid Engine Enterprise Edition Global Grid Model & Interoperability Grid Computing: A New Computing Utility Model Problem-solving through resource pooling in virtual systems Virtualization of Transparent scalability of Resources into a dynamic, single compute resource from federated assets CPU cycles, storage, devices Access that is... Dependable, consistent, pervasive, inexpensive

3 The Grid Computing Solution Breaks boundaries Brings resource diversity/scalability Enables efficient use of resources Optimal development environment for users Paves the way to hosting and outsourcing compute on demand Grid Computing Models: Cluster Grids Usage Simplest grid deployment Single team: Project Department Single site firewall Benefit Optimal alignment of resources, tasks and budgets

4 Grid Computing Models: Campus Grids Usage Multiple teams in organizations share one or more Cluster Grid Single site to enterprisewide Benefit Maximum ROI and utility Grid Computing Models: Global Grids Usage Linked Cluster and Campus Grid Models across many organizations Typically used for research Benefit Creates large virtual system Facilitates collaboration between organizations

9 Grid Computing Adoption Steps CLUSTER GRID MODEL Single Team Single Organization Academic & Research Business CAMPUS GRID MODEL Multiple Teams Single Organization GLOBAL GRID MODEL Multiple Teams Multiple Organizations Why Campus Grid Model? Untapped resources are available for everyone.

10 Campus Grid Model: Key Challenge Lack of Trust My resources won t be available when I need them. Untapped resources are available for everyone. Distributed Resource Management ESSENTIAL COMPONENT FOR COMPUTE FARMS Priority Management Priority Management Policy Management Load Management

11 SGE, Enterprise Edition: Dynamic Scheduling Maintains active low-level control of workload during execution Supports multiple policies Keeps resource utilization aligned with policies Correlates all workload elements Responds to ad hoc needs Sun Cluster Grid Model Solution: Policies and Monitoring Owners negotiate policies Automated tools enforce policies Exceptions for specific needs/events provide flexibility Monitoring ensures policies are enforced

12 Sun Grid Engine Enterprise Edition: Multiple Owners, One Location Campus Grid Model with multiple owners Department resource demand for Project A SGE / Enterprise Edition Policies

13 Grid Computing Adoption Steps CLUSTER GRID MODEL Single Team Single Organization Academic & Research Business CAMPUS GRID MODEL Multiple Teams Single Organization GLOBAL GRID MODEL Multiple Teams Multiple Organizations SGE Interoperability with Globus DELIVERING THE GLOBAL GRID MODEL Joint effort with Globus team announced at SC2001 Demo'd at Argonne National Lab ANL, ARL Army Research Lab, Raytheon, and San Diego SDSC Globus/SGE interaction through GRAM (Globus Resource Allocation Mgr) scripts Globus jobs from ANL submitted to ARL cluster Next step: SGE/EE on top of Globus SGE acting as the resource broker for Globus Globus: multi-site comm., authentication, security, file transfers,... SGE/Broker submits and tracks jobs to remote systems using Globus services

18 Job Types Job types - a mixture of: Batch Interactive (qsh, qrsh, qlogin) Parallel (mpi, pvm, qmake,...) Checkpointing (CPR, Hibernator, Unicos, user defined,...) Array Jobs (unlimited size, massive scalability) Transfer (to other cluster/queuing systems) Submitted with a request profile Dynamically changeable while pending Queues Where a job executes Job class container/description Bound to a host Queue slots = number of concurrently executing jobs Different queue types: batch/interactive... Queues have attributes (e.g. available memory) Users can be owners of queues

19 Complexes Queue Complex all attributes being queue related and requestable (in principle) definition of attribute characteristics (e.g. data type) Host/Global Complex all parameters managed on a host/global level, e.g. load (memory), SW licenses, also total of queue slots definition of attribute characteristics User Defined Complexes free definition and grouping of additional attributes definition of attribute characteristics Consumables Capacity management for limited resources Available memory Free Software licenses Available disk space Available network bandwidth... Cluster global -> host related -> queue specific (inheritance) Link with standard and user defined load sensors
