Installation

Simply type fab localhost install_plugin:fabmogp anywhere inside your FabSim3 install directory.

FabSim3 Configuration

Once you have installed the required dependencies, you will need to take a few small configuration steps:

Go to (FabSim Home)/deploy
Open machines_user.yml
Under the section default:, please add the following lines:
a. mpi_exec=(mpiexec_file_path)
NOTE: you can find it in your local machine by running which mpiexec
Please replace mpiexec_file_path with your actual install path file.
b. fdfault_exec=(fdfault Home)
NOTE: Please replace (fdfault Home) with your actual install directory.

Testing

To run a single job, simply type:
fabsim localhost mogp:demo
To run the ensemble, you can type, simply type:
fabsim localhost mogp_ensemble:demo,sample_points=20
You can copy back any results from completed runs using:
fabsim localhost fetch_results
The results will then be in a directory inside (FabSim3 Home)/results, which is most likely called demo_localhost_16
You can analysis the simulation output using:
fabsim localhost mogp_analysis:demo,demo_localhost_16
