Syntax
STF-USE-HW-STRUCTURE [on|off]
Variable
VT_STF_USE_HW_STRUCTURE
Default
usually
on
Description
If the STF format is used, trace information can be stored in different files. If this option is enabled, trace data of processes running on the same node are combined in one file for that node. This is enabled by default on most machines, because it both reduces inter-node communication during trace file generation and resembles the access pattern during analysis.Iif each process is running on its own node, it is not enabled .
This option can be combined with
STF-PROCS-PER-FILE
to reduce the number of processes whose data is written into the same file even further.

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.
