Hi Galaxy developers,

In our Elixir project (http://www.elixir-europe.org/), Norway, we have five geographically distributed Galaxy instances. Each is working on a local cluster (mostly SLURM). We are planning to interconnect those five clusters using a meta-scheduler ARC (http://www.nordugrid.org/arc/), to achieve load balancing, so that a galaxy job can be reallocated to an external cluster in case that the local cluster is saturated. 

ARC manages the interconnection very well. What we need is to create a Galaxy job handler for ARC. Is there a general template or interface for a job handler, i.e. for defining job submission commands ... etc.?

and how to compile and integrate this new job handler and integrate it into the Galaxy installation?
