Thanks to everyone who has answered this. The short answer is that
torque is not behaving the way I expected and not the way I have ever
seen it behave in the past. The I/O binding of these jobs may have
something to do with this, but I will look into it further.
cheers

That *shouldn't* be the case as the contents of a torque script should
be run sequentially (many jobs depend on this and I've never seen job
parts run out of order), just as a sh script is (they are actually just
csh scripts in my case). My understanding is that the parallelisation
occurs either through using MPI or other parallel compilers or running a
number of torque jobs, BUT I've just tested the hypothesis by running it
as a straight csh script - and it works perfectly, so there must be
something like that going on. I'll ask some of our more experience
torque admins about it. Thanks.
