# vtf2profile(1)

Generate a TAU profile set from a vampir trace file

## NAME

vtf2profile - Generate a TAU profile set from a vampir trace file

## SYNOPSIS

**vtf2profile** \[**-p** *profile*\] \[**-i** *interval\_start* *interval\_end*\] \[**-c**\] \[**-h**\] {**-f** *tracefile*}

## DESCRIPTION

vtf2profile is created when TAU is configured with the -vtf=\<vtf\_dir\> option. This tool converts a VTF trace file (\*.vpt) to a tau profile set (profile.A.B.C where A, B and C are the node, context and thread numbers respectively).

The vtf file to be read is specified in the command line by the -f flag followed by the file's location. The VTF tracefile specified may be in gzipped form, eg app.vpt.gz. -p is similarly used to specify the relative path to the directory where the profile files should be stored. If no output directory is specified the current directory will be used. A contiguous interval within the vtf file may be selected for conversion by using the -i flag followed by two integers, representing the timestamp of the start and end of the desired interval respectively. The entire vtf file is converted if no interval is given.

## OPTIONS

**-f tracefile** -Specify the Vampir tracefile to be converted.

**-p profile** -Specify the location where the profile file(s) should be written.

**-i interval\_start interval\_end** -Limit the profile produced to the specified interval within the vampir trace file.

**-c** -Opens a command line interface for the program.

**-h** -Displays a help message.

## EXAMPLES

To convert a vampir tracefile, trace.vpt, to an equivalent TAU profile, use the following:

```
vtf2profile -f trace.vpt
```

To produce a TAU profile in the ./profiles directory representing only the events from the start of the tracefile to timestamp 6000, use:

```
vtf2profile -f trace.vpt -p ./profiles -i 0 6000
```
