Reading the wiki page for the i960 led me to the Am 29000, which I'd never heard of. Long story short, it was AMD's flavor of Berkeley RISC, and lived long enough to grow into a superscalar design. The last iteration had some of its functional units swiped for use in the K5 architecture, which is off-topic for this thread.

carry on then posted:z systems have some wild capabilities. Parallel Sysplex, firmware-level hypervisor (to enable LPARs), hardware zip compression. LPARs well predate the Z series. I believe they were introduced all the way back with System/370, but they were definitely available on ES/9000 systems under MVS. That's where I started my career. Also available at that time: hot-swappable CPUs. A decade later when I started working for Google I recognized their datacenter design (arbitrarily large collections of "ordinary" machines, any of which are allowed to fail at any time) as the inverse of IBM big iron (singular machines capable of terrific throughput, which are not allowed to fail under any circumstance). Edit: if you never worked with true mainframes, the scale of what they were capable of is kinda hard to realize. In 1998, when your "average" PC had just graduated to 8MB of system RAM, I was using IBM Hiperspaces at work. This was a technique that let you read 2GB chunks of data from mass storage, and shove all those records through your batch processing flow, completely in-memory, before writing them back out to storage after processing. mdxi fucked around with this message at 20:24 on Jan 3, 2022 |
