System Requirements

csWMPI II II can run on standalone machines or clusters consisting of Windows and/or Linux nodes. Any inter-connector supporting TCP-IP can be used, including Fast Ethernet, Gigabit Ethernet, Myrinet, InfiniBand, Quadrics, etc. The number of CPUs that can be used simultaneously is limited by the license. For a trial license this number is 4 CPUs.

The following platforms are supported:

  • Microsoft Windows for x86 32-bit systems
  • Microsoft Windows for 64-bit extended systems
  • Linux for x86 32-bit architectures
  • Linux for 64-bit extended architectures

  • Microsoft Windows for x86 32-bit systems

    Linux for x86 32-bit architectures

    csWMPI II II has been tested and found to work on the following distributions:

    • Fedora Core 4
    • RedHat Enterprise 4
    • SUSE 9.2
    There is a good chance that csWMPI II II will run on other distributions than those listed above, you can always try to install a trial version to see if it works. In case not, please contact us and we will determine whether your distribution can be supported. Moreover, other versions above mentioned distributions are likely to work as well, both more recent version and some earlier versions provided that the requirements listed below are met:

    Installation Privileges root
