Subject: Re: [hwloc-users] CPU info on ARM

I passed this on to my OMPI ARM contact (Leif Lindholm). Here's what he said:

   "It gets a bit trickier on ARM... since we may also have (implementation
    time) configurable cache sizes and also big.LITTLE (different processor
    models executing in the same SMP system)."

He passed the question on to another ARM guy, asking for further detail. I'll pass on what he says.
