It's fairly common that many longtime Linux kernel developers use their personal email addresses for signing off on kernel patches or dealing with other patch work, especially when they are engaging with kernel development in their personal time too and occasionally jumping between employers over time while still sticking to interacting with the upstream kernel community, etc. There are also understandably some companies that mandate the use of their corporate email addresses for their official work/patches while now IBM seems to be taking things one step to the extreme...

One of the exciting elements of last month's AMD EPYC 7003 "Milan" series launch was having same-day availability in public clouds. Microsoft as one of AMD's cloud partners worked closely to deliver launch-day availability in their public cloud using EPYC 7003 series processors with the new "HBv3" instances focused on high performance computing (HPC) virtual machines. Here are some benchmarks of the Azure HPv3 instances compared to prior generation Microsoft Azure HPC instances available on-demand in their cloud.
