NAME

hwloc-assembler-remote - Assemble multiple remote host topologies

SYNOPSIS

hwloc-assembler-remote [options] output.xml host1 host2 ...

OPTIONS

--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.

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.
