NAME
hwloc-assembler - Assemble multiple XML topologies SYNOPSIS
hwloc-assembler [options] output.xml [--name <name1>] input1.xml [--name <name2>] input2.xml ... OPTIONS
-n --name <name> Set <name> in the AssemblerName info attribute of the next input topology root to ease identification within the final global topol- ogy. -f --force Ignore errors while reading input files. -v --verbose Verbose messages. DESCRIPTION
hwloc-assembler combines the input XML topologies and exports the resulting global topologies to a new XML file. All inputs are inserting as children of the global root object. Each input topology root is annotated with info attributes before insertion. AssemblerIndex is set to the index within the list of inputs. AssemblerName is set to the name given with --name if any. hwloc-assembler-remote offers a fron- tend for assembling remote nodes topologies without having to manually gather and transfer each of them. EXAMPLES
To assemble two nodes topologies: $ hwloc-assembler output.xml --name host1 host1.xml --name host2 host2.xml RETURN VALUE
Upon successful execution, hwloc-assembler returns 0. hwloc-assembler will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line. SEE ALSO

NAME
hwloc-distances - Displays distance matrices SYNOPSIS
hwloc-distances [options] OPTIONS
-l --logical Display hwloc logical indexes (default) instead of physical/OS indexes. -p --physical Display OS/physical indexes instead of hwloc logical indexes. -i <file>, --input <file> Read topology from XML file <file> (instead of discovering the topology on the local machine). If <file> is "-", the standard input is used. XML support must have been compiled in to hwloc for this option to be usable. -i <directory>, --input <directory> Read topology from the chroot specified by <directory> (instead of discovering the topology on the local machine). This option is generally only available on Linux. The chroot was usually created by gathering another machine topology with hwloc-gather-topology. -i <specification>, --input <specification> Simulate a fake hierarchy (instead of discovering the topology on the local machine). If <specification> is "node:2 pu:3", the topology will contain two NUMA nodes with 3 processing units in each of them. The <specification> string must end with a number of PUs. --if <format>, --input-format <format> Enforce the input in the given format, among xml, fsroot and synthetic. --restrict <cpuset> Restrict the topology to the given cpuset. -v Verbose messages. --version Report version and exit. DESCRIPTION
hwloc-distances displays also distance matrices attached to the topology. A breadth-first traversal of the topology is performed starting from the root to find all distance matrices. NOTE: lstopo may also display distance matrices in its verbose textual output. However lstopo only prints matrices that cover the entire topology while hwloc-distances also displays matrices that ignore part of the topology. EXAMPLES
On a quad-socket opteron machine: $ hwloc-distances Latency matrix between 4 NUMANodes (depth 2) by logical indexes: index 0 1 2 3 0 1.000 1.600 2.200 2.200 1 1.600 1.000 2.200 2.200 2 2.200 2.200 1.000 1.600 3 2.200 2.200 1.600 1.000 RETURN VALUE
Upon successful execution, hwloc-distances returns 0. hwloc-distances will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line. SEE ALSO
