Samuel,

  That was the magic flag I needed. I had totally misunderstood wha it meant.

Thanks,

Does aprun give you allocation of all cores?  By default lstopo only
shows the allocated cores.  To see all of them, use the --whole-system
option.

[hwloc-users] Building hwloc for a Cray/KNL system

2017-01-27 Thread Gunter, David O 
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
