1.1.1.1 app1 app3 
1.1.1.2 app2 
1.1.1.3 app4


One more question please ...

for the above code, is it possible to write it to unique file based on the first argument - in our case i ?

e.g

Code:
1.1.1.1 app1 app3 > 1.1.1.1_txt
1.1.1.2 app2 > 1.1.1.2_txt
1.1.1.3 app4 > 1.1.1.3_txt

Thx

hwloc-assembler-remote

HWLOC-ASSEMBLER-REMOTE(1)					       hwloc						 HWLOC-ASSEMBLER-REMOTE(1)

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 envi-
	      ronment variable.

       --lstopo-opts <opts>
	      Pass the given lstopo options when gathering remote topologies.

       --show Display the resulting topology before exit.

       -v --verbose
	      Verbose messages.

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.
