Setting up MiGA in a cluster

MiGA is developed to run on clusters with a TORQUE scheduler. The administrator should install the dependencies and MiGA-base on a networked file system.

When you first initialize MiGA, the program will prompt the user for the type of daemon. For a cluster with TORQUE, the user can choose a qsub daemon. During the initialization, MiGA will also ask for the number of jobs to submit and the number of CPUs per job.

After you have setup a MiGA project, you can create a job script to start daemon. The daemon requires to be alive until all the jobs for the have finished, so you should add a long-enough walltime. If you didn't give enough walltime for your job, the MiGA daemon will get killed by the system. In this case, you can restart the daemon again to finish processing the project.

Example job script:

#PBS -N MiGADaemon
#PBS -l mem=2gb
#PBS -l nodes=1:ppn2
#PBS -l walltime=48:00:00
