Meta-Scheduler VS Local Scheduler

• Local Scheduler
• For Cluster Environment
• Same Hardware Architecture, OS
• Typically different Resource Management softwares
  (RMs) like LSF, PBS, and Sun Grid Engine are
  responsible for load balancing and resource
  sharing within each local administrative domain.
• Meta-Scheduler
• For Grid Environment
• Different Hardware, OS, Infrastructure, Local
  Scheduler, Resource Manager
• In a Grid-computing environment, there is a
  common requirement for users to query, negotiate
  access and manage resources existing within
  different administrative domains at Grid level.
  The meta-scheduler is designed to perform such
  global wide policies.

CSF4 Summary

• What is CSF
• Community Scheduler Framework
• CSF4 is a group of grid services host in GT4
• CSF4 is the first GT4-WSRF compliant
  Meta-Scheduler
• Open Source project and can be accessed at
  http//sourceforge.net/projects/gcsf
• The development team of CSF4 is from Jilin
  University, PRC
• CSF4 has been added to Globus Toolkit 4 as an
  Execution Component

CSF4 Functionalities

• Submit, control and monitor jobs at a grid level.
  
• Queue Service for jobs is provided
• Choose satisfied cluster for jobs automatically
• Create and manage advanced reservations for LSF
  cluster.

11
CSF4 FunctionalitiesResource Supported

• Local Scheduler Supported
• LSF (support advanced reservation)
• PBS
• SGE
• Condor
• Infrastructure Supported
• WS GRAM (GT4 GRAM)
• Pre-WS GRAM (GT2 GRAM)

12
CSF4 Functionalities Scheduling Policy
Framework

• A scheduling policy framework is provided so that
  site and user specific scheduling policies can be
  implemented regardless of the underlying resource
  manager.
• User can configure scheduling policies for queue,
  and even write a new scheduling policy as a
  plug-in without modify the source codes of CSF4.

13
Existent Scheduling Policies Plug-in

• FCFS plugin
• First Come First Serve
• Default policy
• always loaded by CSF
• Throttle plugin
• An optional plugin
• Constraint the number of jobs lunched in one
  scheduling cycle

14
Schedule plugin scheduling policies

• Scheduling polices are defined in a queue
• Each policy is implemented inside a scheduling
  plugin module
• A queue can load multiple plugin modules

15
CSF4 Functionalities (cont.)Deploy CSF4 in a
Grid Community

• Multiple CSF4s Can Exchange Cluster Information
  Each Other

Demo Practice

• Before testing
• grid-proxy-init
• cp zding/practice/ .
• scp zding/practice/ USER_at_rocks-170
