A natural r&d project would be a high frequency oms or something like an nyse bid/ask/match book manager.

These apps tend to do kernel bypass anyway for net i/o after hard scrubbing the os to remove as many interrupts and other superfluous jitter the oms does not need.

However, I believe the low level kernel bypass code (eg dpdk, libfabric) depend on Linux to talk to the hw in a disciplined way.

Anybody know better?

A decently faster oms this way could be a practical alternative to fpgas we sometimes see in that space. (hw would be co-located of course)
