I have bumped into the following issue:
This works as expected:utils/hwloc-calc core:0-1 -H puPU:0 PU:1 PU:2 PU:3
Now intuitively one would expect this to work as well (as supported by taskset/numactl commands)utils/hwloc-calc core:0,1 -H puPU:0 PU:1Unfortunately, ",1" is silently ignored.
hwloc-1.8rc1 does better:
$ ./hwloc-calc core:0,1 -H puinvalid character at `,1' after index at `0,1'ignored unrecognized argument core:0,1
+ hwloc-calc and friends have a more robust parsing of locations given on the command-line and they report useful error messages about it.
However, I would vote for the formatobject:index,index1,index2
to be supported and being equivalent to
object:index object:index1 object:index2
What do you think about it?
Thanks a lot!Jirka

The Hardware Locality (hwloc) team is pleased to announce the first
release candidate for v1.8:
v1.8rc1 is the first milestone of a major feature release.
It adds PCI discovery on Linux without dependencies on external libs,
a new API to manipulate differences between very similar topologies,
multiple improvements to command-line tools, and more.
* New components
+ Add the "linuxpci" component that always works on Linux even when
libpciaccess and libpci aren't available (and even with a modified
file-system root). By default the old "pci" component runs first
because "linuxpci" lacks device names (obj->name is always NULL).
+ Add the topology difference API in hwloc/diff.h for manipulating
many similar topologies.
+ Add hwloc_topology_dup() for duplicating an entire topology.
+ hwloc.h and hwloc/helper.h have been reorganized to clarify the
documentation sections. The actual inline code has moved out of hwloc.h
into the new hwloc/inlines.h.
+ Deprecated functions are now in hwloc/deprecated.h, and not in the
official documentation anymore.
+ Add hwloc-diff and hwloc-patch tools together with the new diff API.
+ Add hwloc-compress-dir to (de)compress an entire directory of XML files
using hwloc-diff and hwloc-patch.
+ Object colors in the graphical output of lstopo may be changed by adding
a "lstopoStyle" info attribute. See CUSTOM COLORS in the lstopo(1) manpage
for details. Thanks to Jirka Hladky for discussing the idea.
+ hwloc-gather-topology may now gather I/O-related files on Linux when
--io is given. Only the linuxpci component supports discovering I/O
objects from these extended tarballs.
+ hwloc-annotate now supports --ri to remove/replace info attributes with
a given name.
+ hwloc-info supports "root" and "all" special locations for dumping
information about the root object.
+ lstopo now supports --append-legend to append custom lines of text
to the legend in the graphical output. Thanks to Jirka Hladky for
discussing the idea.
+ hwloc-calc and friends have a more robust parsing of locations given
on the command-line and they report useful error messages about it.
+ Add --whole-system to hwloc-bind, hwloc-calc, hwloc-distances and
hwloc-distrib, and add --restrict to hwloc-bind for uniformity among
+ Calling hwloc_topology_load() or hwloc_topology_set_*() on an already
loaded topology now returns an error (deprecated since release 1.6.1).
+ Fix the initialisation of cpusets and nodesets in Group objects added
when inserting PCI hostbridges.
+ Never merge Group objects that were added explicitly by the user with
+ Add a sanity check during dynamic plugin loading to prevent some
crashes when hwloc is dynamically loaded by another plugin mechanisms.
+ Add --with-hwloc-plugins-path to specify the install/load directories
+ Add the MICSerialNumber info attribute to the root object when running
hwloc inside a Xeon Phi to match the same attribute in the MIC OS device
when running in the host.
