On: Method identified to double computer processing speeds

[orf]

They implemented a kernel driver that processes can submit work items to (multiply this vector, summing reduce et ). It balances the computation across available hardware.

Seems really neat, if not a bit click-baity.

The work would have to be large enough to be worth the cost of kernel context switch IIUC.

What is the (platform) kernel context switching overhead tradeoff for what size workloads of the already implemented functions?
