Meltdown is affects Intel, IBM and ARM CPUs at least and Spectre (IIRC)
potentially affects any CPU with speculative execution.
All the best,

Thanks again, Gavin. We did the same thing at our site this week (mitigated on
login nodes, disabled mitigation on compute nodes), but I intend to go back and
test to see if there’s any performance penalty without the kernel arguments.
Am I correct that this is Haswell and newer that is affected

I was hoping there was some representative CFD model that everyone
could use to evaluate performance. My background is in FEA so am
familiar with matrix decomposition and iterative solvers. I would
guess OpenFOAM implements some kind of iterative solver? So any large
mesh would suit to test
