|Use the given ssh command (and options) to connect to remote hosts.|
|Use the given path as the remote lstopo command when gathering remote topologies. By default, lstopo is taken from the PATH environment variable.|
|Pass the given lstopo options when gathering remote topologies.|
|--show||Display the resulting topology before exit.|
|Ignore failure to load a remote host topology.|
hwloc-assembler-remote is a frontend to hwloc-assembler. It takes care of retrieving the remote nodes topologies before assembling them with hwloc-assembler.
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
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.
