While it isn't bulletproof yet (restarting jobs that fail due to spot instance reclaims, etc), Cloudman (usegalaxy.org/cloud) does currently have support for running worker nodes as spot instances. When you go to add nodes, just click "Use Spot Instances", and add your spot price. For obvious reasons, you wouldn't want the head node of your cluster to be a spot instance, use a normal one for that. -Dannon On Jan 18, 2013, at 11:58 AM, Andrew Norman <anorman07@gmail.com> wrote:

Does anyone have any experience running Galaxy using Amazon's EC2 spot pricing? It seems like that could save a lot of money as compared to on-demand pricing, and it appears that there are ways to mix on-demand and spot instances within one processing cluster:
