One of my older coworkers claims that one of the most impressive things he's seen in his career was an IBM mobile tech demo (mainframe in a semi truck) where the technician conducting the demo would reach into the machine and start randomly pulling out CPUs and memory, and then plugging them back in. The display would show the available resources and throughout of whatever computation they were running for the demo decrease as hardware was removed and then increase as it was added back, and the whole thing happened seamlessly without impacting the compute job.
- zozbot234 6y agoI think CPU and memory hotplug is par for the course these days on many server-class platforms. In fact memory hotplug would be quite useful on mobile hardware since it would allow the OS to power down RAM modules automatically when that memory is not being used, and add them back as needed.
