[galaxy-dev] routing to a cluster or not on a per-tool basis

Hi, I have some tools that run really quickly without using any kind of cluster. I would prefer not to run these tools on a cluster, as the overhead of submitting these jobs makes them take much longer than they otherwise would. I have other tools that are computationally intensive and need to be run on a cluster. I would like to expose all these tools in the same Galaxy instance, but have some tools run on the cluster and others not. Is this possible? Thanks, Dan
