Specify the size of a raw stack (in bytes) to process.

Syntax

-stack-size=
<value in bytes>
Arguments
Possible
<
value

: numbers between 0 and 2147483647
Default
0
The stack size is unlimited.
For driverless sampling collection, the default value is 1024 bytes.
Actions Modified
Description
When you configure a customhardware event-based sampling collection, you may reduce the collection overhead and limit the stack size (in bytes) processed by the
VTune
Profiler
by using the
-stack-size
option.
This example configures and runs a custom event-based sampling data collection with the stack size limited to 8192 bytes:
vtune
-collect-with runsa -knob enable-stack-collection=true -knob stack-size=8192 -knob enable-call-counts=true -knob event-config=CPU_CLK_UNHALTED.REF_TSC:sa=1800000,CPU_CLK_UNHALTED.THREAD:sa=1800000,INST_RETIRED.ANY:sa=1800000 -app-working-dir /home/samples/nqueens_fortran -- /home/samples/nqueens_fortran/nqueens_parallel

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.
