It is ''not'' recommended to debug MPI-parallel binaries with GDB, please read [[MPI]] on how to do that.
Rather parallel debuggers like ARM Forge (formerly Allinea ddt) or Totalview ease debugging with a GUI.

= Loading =
It is possible to choose between several versions of GDB. By default both programs are installed. You can check the version which is currently used with:
<pre>$ gcc --version</pre>
<br>
To use a different version ofGDB, you have to load it through the module system.
For example if you need GDB 10.1, load the <kbd>devel/gdb</kbd> module.

How to load the desired version (e.g. GDB version 9.2):

Introduction

The Score-P Project is a profiling and tracing library with supportive tools developed mainly by by the [VI-HPS] project.

Versions and Availability

A list of versions currently available on all bwHPC Clusters can be obtained from the

Cluster Information System CIS

{{#widget:Iframe |url=https://cis-hpc.uni-konstanz.de/prod.cis/bwUniCluster/devel/scorep |width=99% |height=120 }} On the command line interface of any bwHPC cluster you'll get a list of available versions by using the command module avail devel/scorep. Please note that Score-P installation may be hidden in the sense that it's dependent on the MPI, which in turn is dependent on the compiler. So while there are a multitude of compiler version's only some may feature an MPI, which offers tracing using Score-P. Please use module --ignore-cache spider to evaluate all possible installations. 

$ : bwUniCluster 2.0
$ module load compiler/gnu/10.2 mpi/openmpi ; module avail devel/score
------------------------ /opt/bwhpc/common/modulefiles/Core -------------------------
devel/scorep/6.0


Loading

Score-P may be loaded with a specific and MPI: 

$ module load compiler/gnu/10.2 mpi/openmpi devel/scorep

Check the installation of this Score-P instance using scorep-config: 

$ 
$ scorep-config
