Miser

• Miser is a deterministic batch scheduling
  facility that can be used to balance batch and
  interactive cpu and memory usage.

4
Miser

• Installation
• Miser can be found on IRIX 6.5.9 and higher
  Overlay CD
• Install eoe..miser

5
Miser

• After the installation
• /etc/config/miser.options - pointing to
  -gt/etc/miser.conf
• -gt pointing to
• /etc/miser_system.conf
• /etc/miser_default.conf
• /etc/miser_repack.conf

6
Miser

• Miser consist of following utilities
• miser
• miser_qinfo
• miser_jinfo
• miser_submit
• miser_move
• miser_kill
• miser_cpuset, cpuset

7
Miser

• Queue definition
• see /etc/miser_system.conf

8
Miser - cpusets

• Currently two types of CPUsets supported
• open
• restricted
• Syntax
• cpuset -q cpuset name -A command-c -f
  file-d-l
• -m-Q -c -Q -h

9
Miser - cpusets

• cpuset definition
• file (3 to 8 characters long name)
• Note
• File permissions of the configuration file
  defines the access to the cpuset.
• R - retrieve information about cpuset
• X - attach the process to the cpuset

10
Miser - cpusets

• cpuset definition cont
• EXCLUSIVE
• MEMORY_LOCAL
• MEMORY_EXCLUSIVE
• MEMORY_KERNEL_AVOID
• MEMORY_MANDATORY
• POLICY_PAGE
• CPU

11
Performance Co-Pilot 2.1

• Family of products for Monitoring and Managing
  Systems - level performance
• (Available on IRIX and Linux.)
• PCP Capabilities
• Automated Performance Management
• Retrospective Performance Analysis
• 3-D visualization
• Customization

12
Performance Co-Pilot 2.1

• Installation
• What do you need
• Installation CD - Performance Co-Pilot 2.1
• License! (collector, monitor)

13
Performance Co-Pilot 2.1

• Architecture

14
Performance Co-Pilot 2.1

• Overview
• Unified Performance Metrics Domains
• Performance Metric Domain Agents
• (see /etc/pmcd.conf) (reconfiguration killall
  -HUP pmcd)
• Uniform Naming of Performance Metrics
• pminfo -h pmcdhost network.interface
• pminfo network
• Performance Metrics Metadata, Values and
  Instances
• pminfo -f network - to fetch the data
• pminfo -d network - to display an information
  about the data types

15
Performance Co-Pilot 2.1

• Utilities
• pmchart -h pmcdhost -c CPU
• (see /var/pcp/config/pmchart/ config file for
  the view definition)
• mpvis - CPU utilization
• osvis - general system performance
• pmgsys

16
Performance Co-Pilot 2.1

• PCP Inference Engine
• pmie
• Archive Logs
• pmlogger - fetches performance metrics from pmcd
• These logs can be used for retrospective analysis
  and the VCR paradigm.
