Enable analysis of all processes running on the system.


Actions Modified
For hardware event-based analysis types,
is enabled by default, so only the target process is analyzed. Use
if you want to analyze all processes running on the system. Data on CPU consumption for these other processes shows how they affect the performance of the target process.
Perform the Hotspots analysis (hardware event-based sampling mode) of all processes running on the system.

Product and Performance Information


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.
