Sun Studio - Performance Analyzer

Developing high performance applications requires a combination of compiler features, libraries of optimized functions, and tools for performance analysis. The Sun Studio Performance Analyzer can help you assess the performance of your code, identify potential performance problems, and locate the part of the code where the problems occur. The Performance Analyzer can be used from the command line or from a graphical user interface.

The Performance Analyzer consists of two tools. The Collector collects performance data by profiling and tracing function calls. The data can include call stacks, microstate accounting information, thread-synchronization delay data, hardware-counter overflow data, MPI function call data, memory allocation data and summary information for the operating system and the process. The Collector can collect all kinds of data for C, C++ and Fortran programs as well as profiling applications written in Java.

The Performance Analyzer itself displays the data recorded by the Collector. It processes the data from the Collector and displays various metrics of performance at the level of the program, the functions, the source lines, and the instructions. These metrics are classed into five groups: timing metrics, hardware counter metrics, synchronization delay metrics, memory allocation metrics, and MPI tracing metrics. The Analyzer also displays the raw data in a graphical format as a function of time.

Project lead Marty Itzkowitz demonstrates the basics of the Sun Studio Performance Analyzer, including Java profiling and hardware-counter profiling, in three new screencasts:

Memory Profiling With MPI Analyzer
This note explores memory profiling as discussed in an email thread and shows an example of how to distinguish between heavy-user program memory allocation versus memory allocations within the MPI implementation due to resource congestion.

Profiling MPI Applications
This article details the profiling of Message Passing Interface (MPI) applications with the Sun Studio Performance Tools. Get an overview of MPI performance data and learn how to compile and launch your application for performance profiling.

Introducing the Sun Studio Performance Tools
The Sun Studio performance tools are designed to help answer questions about application performance. This article discusses the kinds of performance questions that users typically ask and describes the model for using the tools, and for building the target executable, along with the data collection process, the data that can be collected. The article also describes the Analyzer and its displays, and shows a number of examples of what it can do and concludes with a testing strategy for the tools, and some planned extensions to their functionality.
