Filtering Capabilities

Application Performance Snapshot can handle applications with thousands of MPI ranks running in parallel. For such applications the aggregated result charts may contain thousands of lines, which makes the results nearly impossible to read.
The tool provides filtering capabilities to make the results tables shorter.
There are two independent filters in the tool, which can be applied to any table diagram:
  • Filtering by key metric
  • Filtering by number of lines
Note
Filters do not skip one line because it is substituted with the message about the skipped lines, which also takes one line.
Filters are enabled by default, and the tool behavior is the same as with the key combination:
–V 1 –T 1 –N 5
To disable the filters entirely, use the
-F
key, or the following key combination:
–V 0 –T 0 –N 0
For details, see the sections below:

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.
