“We scientists are time-constrained,” said Dr. Yamanaka. “Our priority is our research, not managing our clusters. Bright is intuitive to use, and with it I can effectively manage my cluster without wasting time writing scripts, or synchronizing management tool revisions. Provisioning is fast and easy too. I prefer this approach over open source toolkits.”

Cluster Health Management
Goal: provide problem free environment for running jobs
Four elements1. Cluster management automation
2. Regular health checks• Actions that return PASS, FAIL or UNKNOWN
• Can be associated with a settable severity and a message
• Can launch an action based on any response value
3. Pre-job health checks• Let the workload manager hold the job very briefly
• Check the health of each reserved node
• If unhealthy, take the node offline, inform the system administrator
• Let the workload manager reschedule the job to a different set of nodes
4. Hardware stability & performance tests• Very wide range of tests
• May include disk overwrites and reboot(s)
All elements above are configurable and extensible
