allow-multiple-runs

Enable multiple runs to achieve more precise results for hardware event-based collections.

Syntax

-allow-multiple-runs
-no-allow-multiple-runs
Default
-no-allow-multiple-runs
Actions Modified
Description
By default,
no-allow-multiple-runs
is enabled, and a
collect
or
collect-with
action performs a single analysis run. Performing multiple analysis runs can provide more precise results for hardware event-based collections. To enable event multiplexing, specify
allow-multiple-runs
.
This example runs the target application twice, collecting different events on each run.

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.
