no the non mpi version just calls the uniprocessor processor
multi.uni_processor.  The current uniprocessor implimentation is non
optimal by space on single processor machines but will have the same
overhead by time as any other implimentations (barring the use of
command cacheing which may save to object creation overhead)

you should be able to run relax without a --multi command line and
without an mpirun and the uniprocessor implimentations should run.
However, currently when I run it I get The dependency 'mpi4py' has not
been installed is that the problem you have?? I will investigate the problem

correction I have just gone home and run the command on the same
machine remotely and get no messages about dependencies!. if this is
the error you get please tell me.

Ah revelation (realtime messaging and debugging!) in uni_processor I
am using multi.mpi4py_processor.Result_command which will load the
mpi4py_processor module which will result in  load of mpi4py (lines 14
onwards in mpi4py_processor). This is just an oversight due to me
being lazy and winging it while testing corrections on the way ;-)

yep time to go from alpha to beta, glad you like it

indeed thats the intention and design goal ;-)
