Try to support --cpukinds information #57
Description
Came up here. M1 Macs have low- and high-performance cpus. Apparently this "cpu kind" information is available in recent hwloc versions (on master?). We should try to support and output this.
Apparently, since hwloc Version 2.4 lstopo seems to have a --cpukinds option. And in 2.6 they have specifically worked on distinguishing high and low performance cores for M1 mac’s, see https://github.com/open-mpi/hwloc/blob/master/NEWS.
