# tau2profile(1)

convert TAU tracefiles to TAU profile files

## NAME

tau2profile - 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 tau2profile 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:

```
tau2profile 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:

```
tau2profile merged.trc tau.edf -d ./.. -s 250000
```
