I always thought it sounded super cool but it just doesn't exist in the problem spaces I work in. Like kdb+ was specifically designed to be run on bare metal without a full OS in the way of things going fast, and in quant environments where you're trying to shave off nanoseconds on the computations because your company's gone and invested in a dedicated fibre line to trading servers.

That's actually not true at all. No one who cares about nanoseconds is using kdb+ for a production trading system.

It's primarily used for trading research and surveillance, not live trading. And I've never heard of anyone running it without an OS.

kOS is in development though current status is unknown.

For those curious, what they're actually using is FPGAs and custom silicon.
