We have a Cray KNL system with hwloc 1.11.2 installed. When executing lstopo on
a KNL node, I do not get any info on the cores and threads, the way I do on
other Intel cpus.
I downloaded and built the latest git version and built it, but it is giving me
the same output (shown below). Has anyone successfuly built this for this type
of system?
$ ./configure —prefix=~/hwloc-tt --build=x86_64-unknown-linux-gnu
$ make
$ make install
$ aprun -n 1 -L 193 ~hwloc-tt/bin/lstopo-no-graphics
