The document provides instructions for using the Vampir toolchain at Indiana University (IU) and on the BigRed supercomputer. It describes how to run Vampir and VampirServer on the Quarry and BigRed systems, including details on software environments, launching jobs, and locating trace files. Tracing with VampirTrace is also configured to work with specific compiler versions on both systems.

3. General
• Trace creation and visualization does not have to
happen on the same platform!
– You can look at traces created on Quarry (or your
own desktop) on BigRed

– On interactive nodes b005-b008
• You share the node with other people, this is
especially a problem for opening large trace files!
ssh -X b005
