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.
