Document Information


1.  The Simple Performance Optimization Tool (SPOT)

2.  Running SPOT on Your Application

3.  Understanding SPOT Reports



The Simple Performance Optimization Tool (SPOT) can help you diagnose performance problems that can limit the speed of an application. Running your application with SPOT is complementary to running it under the Oracle Solaris Studio Performance Analyzer and looking at the resulting experiment.

Who Should Use This Book

This manual is intended for application developers with a working knowledge of Fortran, C, C++, or Java programming languages. Users of the performance tools need some understanding of the Solaris operating system, or the Linux operating system, and UNIX? operating system commands. Some knowledge of performance analysis is helpful but is not required to use the tools.
