Chipping Away At X86 Hegemony In the Datacenter

December 14, 2020 Timothy Prickett Morgan

Here at The Four Hundred, we have a saying: Anything that makes Power Systems stronger makes IBM i last longer. And part of making IBM i stronger, oddly enough, means just getting behind the idea of diversity of compute in the datacenter and that specifically means countering the notion that the X86 processor (and specifically the Intel Xeon SP implementation of it, but not exclusively because we now have AMD Epyc processors that are viable) is necessarily the only processor in the future of the datacenter.

We have always held this opinion, as you well know, and have …

The Herculean Task Of Applying Spectre/Meltdown Patches

October 1, 2018 Timothy Prickett Morgan

The Spectre and Meltdown speculative execution vulnerabilities are, as our resident chief technology officer and author of the weekly IBM i PTF Guide, Doug Bidwell, is fond of saying, the gift that just keeps on giving.

We had the shock of finding out in January that there were vulnerabilities in all processor architectures that use speculative execution in their instruction chewing engines – that means all existing processors, by the way. There are none that do not use this very useful architectural feature. And then we had the wait to see what the industry would do to patch these …
