Intel® Trace Analyzer and Collector

STF-PROCS-PER-FILE

Syntax

STF-PROCS-PER-FILE <number of processes>

Variable

VT_STF_PROCS_PER_FILE

Default

16

Description

In addition to or instead of combining trace data per node, the number of processes per file can be limited. This helps to restrict the amount of data that has to be loaded when analyzing a sub-set of the processes.

NMCMD

Syntax

NMCMD <command + args> "nm -P"

Variable

VT_NMCMD

Description

If function tracing with GCC 2.95.2+'s -finstrument-functions is used, Intel Trace Collector is called at function entry/exit. Before logging these events, it has to map from the function's address in the executable to its name.
