Hi Dumsani,

Thanks for your help.  I was confident that your suggestion would work, 
but would you believe this?

./simfactory/bin/sim build --thornlist=manifest/einsteintoolkit.th 
--machine=simfactory/mdb/machines/sumo.ini
Error: retrieving Machine entry for Machine 
simfactory/mdb/machines/sumo.ini: Machine 
simfactory/mdb/machines/sumo.ini doesn't exist
Aborting Simfactory.

ls -lAh simfactory/mdb/machines/sumo.ini
-rw-r--r-- 1 ian ian 1.1K Aug 20 14:27 simfactory/mdb/machines/sumo.ini

So I looked in sim --help and tried:

./simfactory/bin/sim build --thornlist=manifest/einsteintoolkit.th 
--mdb=simfactory/mdb/machines/sumo.ini

and that seemed to work, and

./simfactory/bin/sim submit static_tov 
--parfile=par/static_tov_small.par --walltime=8:0:0

started a process, but on one CPU as before.  So I then tried:

./simfactory/bin/sim submit static_tov --machine=sumo 
--parfile=par/static_tov_small.par --ppn=2 --procs=2 --walltime=8:0:0
Error: retrieving Machine entry for Machine sumo: Machine sumo doesn't exist
Aborting Simfactory.

then I tried sumo.ini, path to sumo.ini (but I specified the machine for 
the build so do I need to do this in the sim command as well?) and 
probably a few other things, but still can't get more than one 
core/thread to start.  Phew!

Any other suggestions?

Cheers,

Ian.
