TAU_TREEMERGE.PL(1)
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.
