Recommendations for High-Performance Computing on OpenStack

Over the last year, I’ve been working on use cases with high-performance computing (HPC) on OpenStack.

In this post, I’ll offer some considerations about hosting high performance and high-throughput workloads.

First, let’s start with the three types of architectures that can be used when hosting HPC workloads on OpenStack:

  1. Virtualized HPC on OpenStack

    In this architecture, all components of the HPC cluster are virtualized in OpenStack
  2. Bare-metal HPC on OpenStack

    All components of the HPC cluster are deployed in bare metal servers using OpenStack Ironic
  3. Virtualized head node and bare-metal compute nodes

    The head node (scheduler, master and login node) are virtualized in OpenStack and the compute nodes are deployed in bare metal servers using OpenStack Ironic

Now that you have an overview of the three types of architecture that can deploy HPC software in OpenStack, I’m going to discuss a few OpenStack best practices when hosting these types of workloads.
