[Vm-dev] A fork in the road()

[Ben Coman]

Sharing an interesting paper I bumped into..

in particular Figure 1 - fork versus spawn performance
And something I didn't realise...
> a process using, DPDK with a kernel-bypass NIC [12], or OpenCL with a
GPU,
> cannot safely fork since the OS cannot duplicate the process state on the
NIC/GPU.
> This appears to have been a continuing source of bafflement
> among GPU programmers for a decade at least
