That contract helped keep Progeny alive after the venture capital funding dried up; the company's original plan was to allow customers to reboot their Windows desktop computers overnight to run as a distributed Linux supercomputer.
Servers are cheap on ebay and the older Intel boards (also sold by Dell, Fujitsu,..) can be upgraded to newer CPUs that are either less power hungry or faster with more cores and sort-of HT. HP are generally not upgrade-able and SGI/ia64 is a special case with lots of other custom hardware as usual.
Annoyingly many Linux / gcc developers want to remove ia64 support from their source trees because the architecture is no longer commercially relevant.
As a necrocomputing enthusiast it's quite sad, but not much one can do about.
If only this old junk was as popular as the various homecomputers...

We have found and fixed multiple regressions in the kernel on ia64. As of Linux 5.12, the kernel runs fine on most ia64, there is still one known regression that affects some machines.
Disclaimer: I'm Debian's maintainer for ia64 (and most other older architectures such as m68k).
