Okay?...... That's not what your point was above??? I never refuted that SGI didn't contribute to Linux. I asked for hard evidence that SGI specifically contributed to the subsystems I was talking about. You specifically mentioned SMP and I was talking about single system image clustering. I would need you to please provide information claiming that SGI added either to Linux. Because Linux had SMP support well before SGI got involved with them, I was using it back in the 2.2 days, and according to Google sources it was added in 1996 at the 2.0 kernel

But SGI also contributed file systems and other things to Linux because they actively used that stuff... Firmware interfaces, bus architectures, graphic systems.  Of course SGI references would be all over Linux for those systems.

This article seems to imply that Linus himself wrote SMP support in Linux: https://www.linuxjournal.com/article/3515

Please provide sources that SGI added SMP support into the Linux kernel and more succinctly please provide a reference that Linux supports single system image clustering because I would absolutely love that I have been waiting over 25 years for it...
