Execution Environment
Caelus comes with a Python library called CPL that does not require the sourcing or calling an environment file for every new shell. For example, using potentialSolver:

Previous
$> potentialSolver -noFunctionObjects -writepNew:
$> caelus run -- potentialSolver -noFunctionObjects -writep

Type caelus -h for the complete list of options or refer to the CPL documentation.

Windows Installation Notes

  • The Windows installer is not digitally signed and may cause some browsers to flag the installer as containing a virus. If this occurs, accept the download or try a different browser.
  • Install the prerequisites first, starting with Python. The prerequisites package is an archive that contains four installation packages.
  • During the Python installation choose to add Python to the PATH system environment variable. Otherwise, the Python bin directory needs to be added to the PATH variable manually.
  • For Windows 8, the MPICH2 software requires .NET 2.050727 to be installed. This is provided in the prerequisites package.
  • MPICH2 installation see below.
  • To install Caelus, double click the .exe and follow the on-screen prompts.
  • There are two ways to setup the Caelus environment:
    • If you use the Caelus Python Library (CPL) to run Caelus you do not need to do anything further to set up Caelus other than double-clicking the icon on the desktop.
    • If you want to use the previous method to run Caelus then execute ‘call {Caelus install path}\etc\caelus-environment.cmd’ from a command prompt to configure the environment.

MPICH2 on Windows Installation Notes:

  • During the installation select MPICH2 to be installed for Everyone
  • After installing MPICH2, you may need to add rules to your firewall to allow the mpiexec.exe and smpd.exe programs to communicate through the firewall. This process depends on your firewall configuration.
  • After installing Caelus, Open an admin command prompt by right-clicking on the command prompt icon and selecting “Run as Administrator“. In the command prompt type the following sequence of commands:
    • smpd -install
    • mpiexec -remove
    • mpiexec -register (note you should use your username and password as user and not administrator)
    • mpiexec -validate (should return success)
    • smpd -status (should return ‘smpd running on <hostname>’)
