Name
trace2profile — convert TAU tracefiles to TAU profile files
Synopsis
tau2vprofile [
-d
directory
] [
-s
snapshot_interval
] {
tau_tracefile
} {
tau_eventfile
}
Description
This program is generated when TAU is configured with the -TRACE option.
The trace2profile converter takes a single tau_tracefile (*.trc) and tau_eventfile (*.edf) and produces a corresponding series of profile files. The input files must be specified in that order, with optinal parameters coming afterward. Multi-file TAU traces must be merged before conversion.
Options
-d Output profile files to the specified 'directory' rather than the current directory.
-s Output a profile snapshot showing the state of the profile data accumulated from the trace every 'snapshot_interval' time
units. The snapshot profiles are placed sequentially in directories labled 'snapshot_n' where 'n' is an integer ranging from
0 to to the total number of snapshots -1.
Examples
The program must be run with the tau trace and tau event files specified in the command line in that order. Any additional arguments follow. The following will produce a profile file array, from the TAU trace and event files merged.trc and tau.edf trace file:
trace2profile merged.trc tau.edf
The following will convert merged.trc and tau.edf to a series of profiles one directory higher. It will also produce a profile snapshot every 250,000 time units:
trace2profile merged.trc tau.edf -d ./.. -s 250000
