[Starcluster] Cluster with mixed NODE_INSTANCE_TYPE's

[Hesselberth, Jay]

I have an application where I'm running 1000's of jobs with small memory requirements (e.g. ~500 Mb / job), but there is a periodic job that needs substantially more RAM (~8 Gb).  I've been running clusters with c1.xlarge instances to maximize throughput of the small jobs, but these don't have the necessary RAM.

I was thinking it would be nice to specify clusters with mixed NODE_INSTANCE_TYPES; e.g. configuring a cluster with 4 c1.xlarge instances for throughput and 1 m2.xlarge instance to handle large RAM jobs.  I don't see how this is currently possible (I'm using the experimental starcluster branch).   Is a feature that is planned for the future?

Thanks,
