  Distributed memory infiniband cluster of the Research Area Scientific Computing (established 2011, decommissioned May 2022)
• MACH2: Altix UV 3000
  20 TB + 1728 Cores Shared Memory Machine
  operated by Johann Kepler Universität (JKU) Linz - specialized for highly parallel jobs with large memory demands (2018 - 2023)

7. HPC Specific Software Documentation

• General Purpose GPU Processing On The UIBK Leo Clusters
  Information on using GPU nodes in the UIBK HPC Leo clusters.
• Matlab
  MATLAB is a high-level language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. This document depicts methods and strategies for using matlab efficiently on the HPC systems of the University of Innsbruck.
• Monitoring Processes Using The Jobtop Utility
  Monitoring processes belonging to a job is a key factor in optimizing your workloads for a HPC cluster. This document describes how to use the locally developed jobtop facility allowing to run a specially configured top command on all cluster nodes that run processes of a given job.
• Qiskit
• Setting up Your Windows PC With Putty and Xming
  This document describes how to set up the software on a Windows desktop or notebook necessary for an efficient user experience of central Linux servers. Covered items: Putty terminal emulator, Xming X11 server, settings for Putty and Xterm terminal emulators.
• Singularity: User Defined Software Environments
  Singularity is an environment for running user-defined software stacks such as Docker containers on HPC clusters.
• Totalview Debugger
  The TotalView Debugger is a graphical tool for debugging sequential and parallel (MPI, OpenMP, POSIX threads etc.) programs.
• Using Anaconda for Python and R
  Anaconda is a comprehensive, curated, high quality and high performance distribution for Python, R, and many associated packages for Linux, Windows, and MacOS, intended for use by scientists.
• smbnetfs
  Methods to access Windows file shares from HPC clusters
• Comparison of features of UIBK HPC systems  muss irgwie anders eingebunden werden
