hwloc-assembler-remote - Assemble multiple remote host topologies
hwloc-assembler-remote [options] output.xml host1 host2 ...
--ssh <ssh> Use the given ssh command (and options) to connect to remote hosts. --lstopo-path <path> Use the given path as the remote lstopo command when gathering remote topologies. By default, lstopo is taken from the PATH environment variable. --lstopo-opts <opts> Pass the given lstopo options when gathering remote topologies. --show Display the resulting topology before exit. -f --force 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.
