Software inventory

OpenSUSE Linux 13.1 (64 Bit) will be used at the control computer dirac-meister and the computing nodes.

Programming languages and environments

For programm development there are compilers for

  • C
  • C++
  • Java

from different origins:

  • GNU compiler suite (4.8.1) gcc, g++, gcj and gfortran
  • Intel compiler (15.0.4) für C icc, C++ icpc and FORTRAN ifort with graphical debugger idb and Intel Math Kernel Libraries MKL (contains BLAS and parts of LAPACK)

Parallel environments

For cluster designed parallel runtime environments

  • openMPI 1.8.8 für GNU- und Intel-Compiler with or without RDMA with infiniband

are provided.

After login all programs are available. The correct parallel environments must be selected by special scripts.

Special program packages

In /opt there are some speical program packages preinstalled:

  • *Crystal14
    CRYSTAL is a general-purpose program for the study of crystalline solids, and the first which has been distributed publicly.

  • GROMACS 5.1.2 with Infiniband RDMA
    A molecular dynamics package primarily designed for biomolecular systems such as proteins and lipids. It is a free software.

Status monitor

The operation is controlled by teh Open Grid Scheduler/Grid Engine.

You may monitor the state of the cluster with the address


in real time and up to one year before.

Availabilty of software from the intranet

At the computing nodes, only /opt with cluster local installed software is reachable. /home is reachable, too. Programs with pathes beginnung with /net/ are unreachable.

At dirac-meister the directories with

  • central home directories /net/home,
  • central temporary storage /net/temp,
  • central group directories /net/group,
  • local directories on workplace PCs /chmi/computername)

are available.

The control computer dirac-meister can be used as a gateway to these directories.
