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.
If
STF-USE-HW-STRUCTURE
is enabled, then
STF-PROCS-PER-FILE
has no effect unless it is set to a value smaller than the number of processes running on a node. To get files that contain exactly the data of
<n>
processes, set
STF-USE-HW-STRUCTURE
to
OFF
and
STF-PROCS-PER-FILE
to
<n>
.
In a single-process multi-threaded application trace, this configuration option is used to determine the number of threads per file.
