Ah, sorry, hostname was supposed to be an environment variable that
contains the hostname, but there is no such thing :)
However, this could work:
mpirun --prefix /opt/openmpi-1.10.0 --hostfile node1 -np 44 sh -c
"/usr/bin/env HWLOC_XMLFILE=/etc/hwloc_\`hostname\`.xml python testmpi.py"
so that hostname gets execute by the remote shell, not the local shell.
