In addition to what Jody said: I wish there were guides like we had
for LAM/MPI, but we simply haven't had the resources to write them.
If the FAQ doesn't have what you need, please let us know and perhaps
we should add to it.

Hi
Actually all you need is in this faq:
http://www.open-mpi.org/faq/?category=running
The analogues to the lam-mpi hostfiles is discussed here
http://www.open-mpi.org/faq/?category=running#mpirun-host
and here
http://www.open-mpi.org/faq/?category=running#mpirun-host
There is no booting required.
All you do is start your application with mpirun
mpirun --hostfile my_hostfile -np 4 my_parallel_application

Hi
Could someone help me out with some documentation? I'm searched
the faq
and can't find exactly what I'm after - which is a sort of setup
guide.
Thus far, I have a couple of Ubuntu nodes running openmpi-1.2.6.
I've
currently got one setup so it can ssh into the other without a
password so I
guess all I need to do now is to run the job. With lam, there was
lam-bhost.def but I've not (this is where I need the help) found any
documentation that talks about the hostfile. The only thing I can
find is
http://www.open-mpi.org/faq/?category=running#simple-launch
but with lam, as I recall there were a whole host (no pun
intended!) of
configuration files and some test scripts like recon and lamboot to
"boot
the supercomputer". Are there no such files here?
I hope this doesn't offend - I have searched the faq but I can't find
exactly what I'm after - is there a setup guide somewhere?
Thanks
Rob
