Good point ... thanks for the clarification.

As a side note, HPC means very different things to different people. In the circles I move in, HPC is interested in running compute jobs that are CPU-intensive, require large amounts of memory, and need low-latency/high-bandwidth interconnects to allow the user to break up a tightly coupled compute job across multiple nodes. A particular compute job will run for hours to days, so fast provisioning isn't necessarily critical (the traditional HPC model is to have your job wait in a batch queue until the resources are available).

I've recently had inquiries about High Performance Computing (HPC) on Openstack. As opposed to the Service Provider (SP) model, HPC is interested in fast provisioning, potentially short lifetime instances with precision metrics and scheduling. Real-time vs. Eventually.

Anyone planning on using Openstack in that way?

If so, I'll direct those inquires to this thread.

Thanks in advance,
