1 Introduction

Vampir and VampirServer are performance analysis tools developed Technical University of Dresden. With support from the Ministerium für Wissenschaft, Forschung und Kunst (MWK), all Universities participating in bwHPC (see bwUniCluster_2.0) have acquired a five year license.

2 Versions and Availability

A list of versions currently available on all bwHPC-C5-Clusters can be obtained from the
Cluster Information System CIS {{#widget:Iframe | url=https://cis-hpc.uni-konstanz.de/prod.cis/bwUniCluster/devel/vampir | width=99% | height=120 }}

On the command line please check for availability using module avail devel/vampir. Vampir provides the GUI and allows analysing traces of few hundred Megabytes. For larger traces, you may want to revert to using a remote VampirServer run in parallel on the compute nodes.

Application traces consist of information gathered on the clusters prior to running Vampir using VampirTrace or Score-P and include timing, MPI communication, MPI I/O, hardware performance counters and CUDA / OpenCL profiling (if enabled in the tracing library).

$ : bwUniCluster 2.0
$ module avail devel/vampir
------------------------ /opt/bwhpc/common/modulefiles/Core -------------------------
devel/vampir/9.9

Attention!
Do not run vampir on the head nodes with large traces with many analysis processes for a long period of time.

Please use on of the possibilities listed below.

5 VampirServer commands

If You want to run VampirServer as part of Your job-script, e.g. after finalizing Your application's run, add the following to your Batch script:

module load devel/vampir
vampirserver start mpi

This shell scripts starts the MPI-parallel version of the VampirServer in the existing, already running SLURM job. The results of starting VampirServer is stored in $HOME/.vampir/server/list; you may check using the below commands, or by checking this file directly.

15 1604424211 mpi 20 uc2n001.localdomain 30000 2178460

Where the first column is the server number (incremented), the third column is the parallelisation mode VAMPIR_MODE, the next column is the number of tasks, followed by the name of the node (uc2n001) and the port (30000).

The commands available to the vampirserver shell script are

Command	Description
help	Show this help
config	Interactively configure VampirServer for the given host system.
list	List running servers including hostname and port (see file $HOME/.vampir/server/list).
start [-t NUM] [LAUNCHER]	Starts a new VampirServer, using -t number of seconds with LAUNCHER being either smp (default), mpi and ap (Cray/HPE only)
stop [SERVER_ID]	Stops the specified server again
version	Print VampirServer's revision
