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

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
