[Beowulf] Have machine, will compute: ESXi or bare metal?

No reason you can’t, especially if you’re not interested in benchmark runs (there’s a chance that if you ran a lot of heavily-loaded VMs, there could be CPU contention on the host).

Any cluster development work I’ve done lately has used VMware VMs exclusively.

I purchased a Cisco UCS C460 M2 (4 @ 10 core Xeons, 128 GB total RAM) for $115 in my local area.  If I used ESXi (free license), I am limited to 8 vcpu per VM.  Could I make a virtual Beowulf cluster out of some of these VMs?  I'm thinking this way I can learn cluster admin without paying the power bill for my ancient Opteron boxes and also scratch my illumos itch while computing on Linux.

Thank you!
