tcollect, Qtcollect

Inserts instrumentation probes calling the Intel® Trace Collector API.

Syntax

Linux:
-tcollect
[
lib
]
macOS:
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.
This trace analyzing/collecting feature requires installation of another product. For more information, see .
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).
Be careful with full instrumentation because this feature can produce very large trace files.
Alternate Options
None
