Hardware locality (hwloc)
When we report an error during insertion, it's hard to figure out where it comes from because it occurs deep inside the insert_by_cpuset() recursion and we only have information about...
libfabric 1.7 will expose device attributes (including name and PCI bus id). We'll finally be able to do something similar to hwloc/openfabrics-verbs.h However it looks like no libfabric provider implements...

Not really useful as long as we don't have hundreds of children within a single object. The quadratic complexity is negligible on current machines since we usually have tens of...
Many attributes are always shared between all cores of a package, or even between packages if same model or generation (how do we know for sure it's homogeneous?). See if...
