These analyzer command options control the behavior of Performance Analyzer and are divided into the following groups:
Experiment options
Java options
Control options
Information options
These options specify how to handle experiments that you specify on the command line.
Start Performance Analyzer and compare the specified experiments.
The base-group is either a single experiment or a groupname.erg file which specifies multiple experiments. The compare-group is one or more experiments that you want to compare to the base group.
To specify multiple experiments in the compare group, separate the experiment names with spaces. You can also specify a groupname.erg file which specifies multiple experiments in the compare group.
Example 4-1 Sample Commands for Opening Experiments in Comparison ModeOpen the experiment test.1.er and compare it to test.4.er:
% analyzer -c test.1.er test.4.er
Open the experiment group demotest.erg and compare it to test.4.er:
% analyzer -c demotest.erg test.4.er
These options specify settings for the JVM that runs Performance Analyzer.
Specify the path to the Java software for running Performance Analyzer. When the –j option is not specified, the default path is taken first by examining environment variables for a path to the JVM, in the order JDK_HOME and then JAVA_PATH. If neither environment variable is set, the JVM found on your PATH is used. Use the –j option to override all the default paths. See
Specify the JVM options. You can specify multiple options. For example:
To run the 64–bit Performance Analyzer, type:
analyzer -J-d64
To run Performance Analyzer with a maximum of JVM memory of 2 Gbytes, type:
analyzer -J-Xmx2G
To run the 64–bit Performance Analyzer with a maximum JVM memory of 8 Gbytes, type:
analyzer -J-d64 -J-Xmx8G
These analyzer command options control the location of the user directory where your settings are stored, set the font size of the user interface. and display the version and runtime information before starting Performance Analyzer.
Specify the font size to be used in the Performance Analyzer user interface..
To start Performance Analyzer and display the menus in 14-point font, type the following:
analyzer -f 14
Display version information and Java runtime arguments and then start Performance Analyzer.
These options print information about analyzer to standard output. The individual options below are stand-alone options. They cannot be combined with other analyzer options nor combined with target or experiment-list arguments.
Display version information only and do not start Performance Analyzer.
Print usage information and exit.
