Add new target machines

Add new target machines

In order to add a new target machine the following steps have to be performed:

  1. Add a new keyword and the corresponding remote directory to your DESTINATIONS file. Let’s call the new target keyword in this example new-target. Then the new line in your DESTINATIONS file could look like new-target user@new-target:/data/user/IOW_ESM. Add new_target to the AVAILABLE_TARGETS file in the root directory.

  2. Add a build script for each component that should be build on the new target. For the example this must be called build_new-target.sh. In general the name has to be build_ followed by the keyword and .sh. In most cases you can probably copy the build script from another target and simply adapt the loaded modules or paths. You have to find out on your own which modification are to be done here.

  3. Add a script that starts the build script on the target. For the example this must be called start_build_new-target.sh. In general the name has to be start_build_ followed by the keyword and .sh. On some targets the build is performed using the queuing system on others it can be performed on directly the login node. Find out which is true for your new target. The existing start_build_haumea.sh is an example for using the queue, whereas start_build_hlrng.sh is an example for direct compilation on the login node.

  4. Add a machine settings python module machine_settings_new_target.py to the directory scripts/run. Here you have to specify how MPI and the queueing system are used on the new target. As a template you can use the examples machine_settings_hlrn.py (Intel-MPI + SLURM) and machine_settings_haumea.py (OpenMPI+SLURM).
