In the 'old' days, I worked for the Atomic Energy Commission
designing, building and maintaining computer controlled experiments using
radiation from and located on the face of the reactor.....our SDS
"mainframe" <G> ran ALL experiments (including some x-ray
diffraction projects in remote locations) in real-time......that computer
had 16K core memory.......and people came from all over the world to see
what we were doing....now a watch has more memory.....
Time flies, and the only constant is change......

Yes - I am not saying my entire
farm has that much ram. You can get away with much, much less, but I have
servers that go that high.

Did I read that right you have 768GB of RAM?

This is kinda new to me - Just so I am clear - unganged systems would
perform better if I have say - a caching system with limited threads each
pined to a specific core (we do this for processor cache anyway) while
ganged systems would perform better it I was spinning up a new thread for
each request and had a large amount (say 768GB) of ram running something
like PostgreSQL where threads are being fired up and down many thousands
of times a second but the data they seek is mostly in main
memory.

On-board bios usually will not allocate that much however. And by
usually will not I mean I have never sen it do so, even in the days of
ghetto ram thieving by graphics chip-sets.

But why does CentOS not register all of my memory? Why less than 3/4
of it?
Perhaps the bios has allocated a chunk of it to onboard
video?

A mouse trap, placed on top of your alarm clock, will prevent you
