The Pablo Performance Capture Facility (PCF), is a cross-platform tool designed to analyze the I/O activity of application codes running under Linux, Solaris, AIX, and IRIX. The code is written in ANSI C++ and can be easily ported to other operating systems. Pablo PCF supports MPI and distributed systems that use parallelism other than MPI and enables the use of threaded code, which provides a variety of options for recording captured performance metrics. In the current implementation, Unix I/O, HDF, and MPI-I/O operations can be monitored.
The PCF provides the user with the option of either recording the performance metrics from I/O operations to trace files written in the Pablo SDDF format or of monitoring the activity remotely using the Pablo Autopilot facility. If SDDF trace files are produced, these can be analyzed using the appropriate analysis tools designed to produce statistical reports for the Unix I/O, MPI- I/O or HDF activity which occurred during execution of the application. If the I/O activity is monitored remotely via Autopilot, then the user may employ tools of his or her own design to interpret the data.
The following links describe how to used the PCF and how to obtain the software.
