STF-USE-HW-STRUCTURE

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.
