I am interested in getting this to work as I am working on implementing
support for dynamic scheduling in Torque. I want any node in an MPI-2
job (basically Open MPI implementation) to be able to request the
Torque/PBS server for more nodes. I am doing a little study in that
right now. Instead of nodes talking directly to the server, I want them
to be able to talk to Mother Superior and MS instead will talk to the

Could you please explain why this does not work now? And why it works
when I do the tm_init from MS, and only does not work from any other MOM?
