Grid-enabled Performance Monitor
Main Features of the G-PM

• G-PM provides a predefined set of standard
  performance metrics for MPI applications.
• G-PM supports a probe mechanism which allow to
  inspect application control flow in run time and
  retrieve content of internal application
  variables.
• A dedicated Performance Measurement Specification
  Language can be used to define new performance
  metrics, specific to a given monitoring scenario.
• Supports narrowing of performance monitoring to
  any set of computing sites, nodes, processes or
  application code regions.
• Provides a convenient Graphical User Interface
  with a set of performance visualization widgets.
• Retrieves low level performance data via
  appropriate programming of the CrossGrid OCM-G
  service.

Goals of G-PM G-PM is a performance monitor for
parallel grid applications. It was designed to
provide performance data in an on-line fashion
and can be easily applied to virtually any
monitoring scenario. Target users
community G-PM is provided for the users of
parallel grid-enabled applications as well as
their developers. Supported Platforms G-PM was
developed for Linux operating system running on
i386 platform. Tested on RedHat Linux 7.3 and
Slackware Linux 8.1. The X Window system and
OCM-G monitoring infrastructure are needed to run
G-PM
Performance Measurement with the G-PM

• Standard performance metrics
• Operation invocation count and delay
• in point-to-point and group communication
• Data volume
• in point-to-point communication
• Application related
• CPU time
• Memory size
• Grid infrastructure related
• CPU load,
• Other
• User-defined metrics
• Based on probes, i.e. special functions inserted
  into program source code to mark certain
  execution points
• Based on combining or transforming standard
  metrics, e.g. dividing results of one metric by
  results for another
