reduce-site-overhead

Examine specified annotated sites for opportunities to reduce site overhead in a Suitability report.

Syntax

--reduce-site-overhead
=
<string>
Arguments
<string>
is a comma-separated list of sites (no spaces).
Default
No default argument
Actions Modified
report
=suitability
Usage
Site overhead is the time spent starting up (and shutting down) parallel execution. It includes creating threads, scheduling those threads onto cores, and waiting for the threads to begin executing.
Usage of this option simulates parallel execution with the assumption that site overhead is zero for a specified site.
Generate a Suitability report. Examine the annotated sites
myAnnotatedSiteJ
and
myAnnotatedSiteX
for opportunities to reduce site overhead. Write the report to
stdout.
$ advixe-cl --report=suitability --project-dir=./advi --reduce-site-overhead=myAnnotatedSiteJ,myAnnotatedSiteX

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.
