Confusion Clear-up
There was some confusion on the last post about fah6 and what that meant. I currently do devops/platform engineering/cloud engineering for my day job. One of the tenants I hold dear is to treat servers like “cattle not pets”. So even though I want to name the servers after all the characters in the Fifth Element, I won’t.
Here’s a current snapshot of VMs from Xen Orchestra.
I’m new to Xen, and it’s a lot to learn. I have found it neat to work a layer under where I do for my day job. Each VM is running Ubuntu 22.04. By the way, are you all interested in the specs of the servers? Let me know in the comments!
Back to the point(s)!
So, 20 CPUs PPD seems to be within the margin of error. I’ve checked in on this one a few times over the last few days to see if there were any outliers. Nope. Just chugging’ along.
Next experiment
I had some suggestions come in (thank you!) from some fellow folders and some HPC experts. It seems there are two experiments to do.
- Turn off SMT
- Lock VMs to one CPU socket.
Turning off SMT requires less googling, so I’m gonna start with that on fah6. I’ll save the Xen cli googling for next time.
