They’re coming back after selling it to Lenovo.

IBM never left HPC. They sold off their x86 lines, but all their big toys run POWER variants.

Selling what to Lenovo? Thinkpad? That's hardly a supercomputer.

I'm not aware of any supercomputers built by Lenovo. IBM has built a lot.

Currently highest ranked Lenovo is #8.

That's a lot of laptops.

TIL! Thanks.

IBM had to sell a Cray computer to NOAA after they sold their server line to Lenovo. https://www.noaa.gov/media-release/noaa-announces-significan...

There are plenty of System X HPC installs. They just no longer come from IBM. Even when IBM still owned the line, it was being outsourced. The University of California SRCS system from ~10 years ago was an iDataPlex sold to us by IBM. Most of the boards had Asus marked on them.

Also remember the System X line was sold way after the Think lines.
