[Beowulf] Performance impacts of Zombieload mitigation

[Chris Samuel]

Hi folks,

There are initial benchmark results on the Zombieload mitigations up on 
Phoronix, unsurprisingly it looks like context switches & IPC take the 
brunt of the impact.

They've expanded their coverage here now (not had time to read yet).

They don't seem to benchmark any CPU intensive code so it'll be 
interesting to see how this impacts MPI & multithreaded HPC codes.

All the best!
Chris
