2.3 General Runtime Options

The following is a list of runtime options available with the same semantics for all tracemodes:

• +traceroot DIR: place all generated files in DIR.
• +traceoff: trace generation is turned off when the application is started. The user is expected to insert code to turn tracing on at some point in the run.
• +traceWarn: By default, warning messages from the framework are not displayed. This option enables warning messages to be printed to screen. However, on large numbers of processors, they can overwhelm the terminal I/O system of the machine and result in unacceptable perturbation of the application.
