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.
