what is wrong with this line?
system ("$ssh '$perf_stats' < temp_pipe 2>&1 &");
I need to start and interact with my executable defined by perf_stats on a remote machine but not change my command line to that of the remote machine. temp_pipe is a node created by mknod -f temp_pipe

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`
