Volker Will: Best thing you can do to a Mac Mini? No, wait, certainly not the right way to start this post.
I am going prepare a Mac Mini in such a way that you will be able to install a 2 or more node HPC cluster and a head node. Once you followed the steps outlined in the videos you will be able to install a fully functional HPC cluster environment, literally a cluster-in-one-box. This post covers all aspects from reinstalling the Mac OS with fewer options, using less space on the disk to a Boot Camp installation of Windows Server 2008 and configuring Hyper-V. The final steps necessary to install the HPC cluster software are outlined in Giovanni’s document on windowshpc.net.
Why this exercise? Because the small form factor of a Mac Mini makes it an easy to carry demo system and/or a sweet little cluster-in-a-box for testing and development.
Instead of writing up the process and posting screenshots, I screen-recorded all the major events of the installation and configuration. if you just try to do some of the stuff I did or have a different hardware, each individual video should make sense by itself.
