I don't need to multiplex HPC jobs and VMs. This is exactly the setup I want to make. This way we can provide users the ability to create their own HPC clusters with their own templates for worker nodes as configurable environment. > CloudStack won't help with the actual parallelizing, that's not what it's made for. CloudStack can help to create highly configurable virtual infrastructure for HPC jobs that can be used by organizations that care about strong privacy of the submitted information and by those individuals that want root access to their HPC nodes. > If you wanted an optimized VM instance, for true HPC, you would need to set it up on hypervisors with PCI passthrough, some type of low latency network like infiniband. In addition you could have GPU instances (like on Amazon), if you had GPUs on your hardware. Infiniband and GPU nodes are available. The task is to make them available through CloudStack. I would appreciate more information on configuring optimized VMs. #Serge
