The FAQ talks about building support for memory affinity by adding –with-libnuma=<path>

 

However, I did not do that, and yet when I check ompi_info, it looks like there is support from the hwloc module.

 

Can I assume the FAQ is a little stale and that –with-libnuma is not really necessary anymore?
