tcollect, Qtcollect

Inserts instrumentation probes calling the Intel® Trace Collector API.

IDE Equivalent

Architectures

IA-32 architecture, Intel® 64 architecture, IA-64 architecture

Syntax

Linux:	-tcollect[=lib]
Mac OS:	None
Windows:	/Qtcollect[=lib]

Arguments

lib

Is one of the Intel® Trace Collector libraries; for example, VT, VTcs, VTmc, or VTfs. If you do not specify lib, the default library is VT.

Default

OFF	Instrumentation probes are not inserted into compiled applications.

Description

This option inserts instrumentation probes calling the Intel® Trace Collector API. To use this option, you must have the Intel® Trace Collector installed and set up through one of its set-up scripts. This tool is available from the Intel® Premier Support web site; it is a component of the Intel® Trace Analyzer and Collector.

This option provides a flexible and convenient way of instrumenting functions of a compiled application. For every function, the entry and exit points are instrumented at compile time to let the Intel® Trace Collector record functions beyond the default MPI calls. For non-MPI applications (for example, threaded or serial), you must ensure that the Intel® Trace Collector is properly initialized (VT_initialize/VT_init).

Caution

Be careful with full instrumentation because this feature can produce very large trace files.

For more details, see the Intel® Trace Collector User Guide.
