Parallel Performance Wizard 1.2 (Default branch)
Parallel Performance Wizard (PPW) is a performance analysis tool designed for UPC, MPI, and SHMEM programs. It features an easy-to-use interface and tight integration with GAS programming models via the GASP interface. It is known to work on many platforms. This project is part of a study of existing and emerging performance analysis theory and tools, current and future HPC architectures, and usability and user productivity preferences and methods, along with various programming models.

PMDASYSTEMTAP(1)					       Performance Co-Pilot						  PMDASYSTEMTAP(1)

NAME

       pmdasystemtap - Systemtap performance metrics domain agent (PMDA)

DESCRIPTION

       pmdasystemtap is a Performance Metrics Domain Agent (PMDA) which exports metric values from the Linux Systemtap dynamic tracing toolkit.

       This implementation uses the stap(1) tool, which is a front-end to the Systemtap toolkit.

INSTALLATION

       In order to access performance data exported by Systemtap from with PCP, it is necessary to perform two configuration steps:

       1.  Configure Systemtap probes, and verify them with stap(1).  These should be produced in a format that is easily parsed, and then stored
	   in the $PCP_PMDAS_DIR/systemtap/probes.stp file.

       2.  Configure pmdasystemtap to extract the values from the text produced by stap.  Two example probes are implemented in the default
	   systemtap PMDA script - readdir and sync traces (see $PCP_PMDAS_DIR/systemtap/pmdasystemtap.pl for details).

	       # cd $PCP_PMDAS_DIR/systemtap
	       # [ edit probes.stp, test /usr/bin/stap probes.stp ]
	       # [ edit pmdasystemtap.pl ]

       Once this is setup, you can access the names and values for the systemtap performance metrics by doing the following as root:

	       # cd $PCP_PMDAS_DIR/systemtap
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/systemtap
	       # ./Remove

       pmdasystemtap is launched by pmcd(1) and should never be executed directly.  The Install and Remove scripts notify pmcd(1) when the agent
       is installed or removed.

FILES

       $PCP_PMDAS_DIR/systemtap/probes.stp
	   probe configuration file for stap(1), run by pmdasystemtap

       $PCP_PMDAS_DIR/systemtap/Install
	   installation script for the pmdasystemtap agent

       $PCP_PMDAS_DIR/systemtap/Remove
	   undo installation script for the pmdasystemtap agent

       $PCP_LOG_DIR/pmcd/systemtap.log
	   default log file for error messages from pmdasystemtap
