NAME¶
tau_treemerge.pl - combine multiple node and or thread TAU tracefiles into a
merged tracefile
SYNOPSIS¶
tau_treemerge.pl
[-n break_amount]
DESCRIPTION¶
tau_treemerge.pl is generated when TAU is configured with the -TRACE option.
This tool assembles a set of tau trace and event files from multiple multiple
nodes or threads across a program's execution into a single unified trace
file. Many TAU trace file tools operate on merged trace files.
tau_treemerge.pl will generate the specified merged trace file and an event
definition file, tau.edf by default.
OPTIONS¶
-n break_amount set the maximum number of trace files to merge in each
invocation of tau_merge. If we need to merge 2000 trace files and if the
maximum number of open files specified by unix is 250, tau_treemerge.pl will
incrementally merge the trace files so as not to exceed the number of open
file descriptors.
