  1. Cluster-on-Demand (COD) Justin Moore Duke University

  2. How Big Is It? • 500? 5000? 25,000? • Clusters are growing • Clusters are expensive • Power, A/C, Management … • How to manage {heat, power, failures}? • How to keep everything organized? • How to divide resources?

  3. How Do You Use It? • We’ve got good middleware • Batch queues, Internet Services, research apps … • But customers are very picky • “Linux!” “FreeBSD!” “Windows!” “Minix!” “Minix??” • “I only need it for 30 minutes!!” • Customers != administrators • Contributing to the problem, not the solution • How to share and manage our clusters? “Can’t we all just get along??”

  4. COD: The More the Merrier • Automated framework for resource management • Owners define policies, customers define configs • COD creates, configures dynamic virtual clusters • Isolated, secure collection of nodes • Backed by network storage • Automatic configuration: fast and OS-agnostic • Middleware negotiates allocations with COD • Virtual Cluster Manager: COD-aware layer

  5. Dynamic Virtual Clusters Reserve pool (off-power) DB Ninja Virtual Cluster COD Manager Node reallocation Example: CNN on 9/11 SGE Virtual Cluster

  6. Those Wonderful Toys • Leverage open standards and open source • DHCP, NFS, NIS, XML • Only constraint is that Linux must support hardware • PXELinux-based installer, RHAT/Debian tools • Currently testing working COD prototype • Core of policy-based scheduling engine: CSP-solver • Framework of node requests + allocation negotiation • OS- and filesystem-agnostic installer • Testbed to examine policies and microbenchmarks

  7. COD: Size Doesn’t Matter • Enable management scalability for hosting centers • Hierarchical policy-driven mechanisms • Empower owners and customers Details and paper at http://www.cs.duke.edu/~justin/cod/
