distrubuted iops measuring

Hi,

I would like to measure IOPS on a distributed file system from several 
hosts in parallel.
I am a bit lost in what options I should use. I would like to have each 
host in a cluster accessing its own file to not stress metadata and/or 
locking infrastructure. I thought that on all clients, I should run just:

fio --server

And from an admin node something like

fio --client server1 job.desc.1 --client server2 job.desc.2 --client 
server3 job.desc.3...., where job.desc.X is specific to the client 
(different filename).

But it seems like each host executes each job file, which is not what I 
would like...
I bet there is a way how to accomplish this. Could you please point me 
to the right direction?

Thank you
Jiri Horky
