Collecting Data From MPI Programs

The Collector can collect performance data from multi-process programs that use the Message Passing Interface (MPI).

The Collector supports the Oracle Message Passing Toolkit 8 (formerly known as Sun HPC ClusterTools 8) and its updates. The Collector can recognize other versions of MPI; the list of valid MPI versions is shown when you run collect -h with no additional arguments.

The Oracle Message Passing Toolkit MPI software is available at for installing on Oracle Solaris 10 and Linux systems.

The Oracle Message Passing Toolkit is made available as part of the Oracle Solaris 11 release. If it is installed on your system, you can find it in /usr/openmpi. If it is not already installed on your Oracle Solaris 11 system, you can search for the package with the command pkg search openmpi if a package repository is configured for the system. See the manual Adding and Updating Oracle Solaris 11 Software Packages in the Oracle Solaris 11 documentation library for more information about installing software in Oracle Solaris 11.

For information about MPI and the MPI standard, see the MPI web site . For more information about Open MPI, see the web site .

To collect data from MPI jobs, you must use the collect command; the dbx collector subcommands cannot be used to start MPI data collection. Details are provided in Running the collect Command for MPI.
