DESCRIPTION
hwloc-assembler-remote is a frontend to hwloc-assembler. It takes care of retrieving the remote nodes' topologies before assembling them with hwloc-assembler.
EXAMPLES
To assemble three nodes topologies:
$ hwloc-assembler-remote output.xml host1 host2 host3
To assemble the topology of a multi-process MPI job defined as a machinefile:
$ hwloc-assembler-remote output.xml `cat machinefile | sort | uniq`
RETURN VALUE
Upon successful execution, hwloc-assembler-remote returns 0.
hwloc-assembler-remote will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line.
