I've done this sort of thing in the past with fork and exec.

To serialize the jobs on the machines, the easiest thing is to just send
the commands all at once to a given machine, like "command1; command2;
command3".

You can use waitpid or similar to check if a series of jobs has finished
on a particular machine.

An example of something similar can be found athttp://stromberg.dnsalias.org/~strombrg/loop.html

(If you look at the code, be kind. I wrote it long ago :)

There's a benefit to saving the output from each machine into a single
file for that machine. If you think some machines will produce the same
output, and you don't want to see it over and over, you can analyze the
files with something likehttp://stromberg.dnsalias.org/~strombrg/equivalence-classes.html.

Hi,

I want send my jobs over a whole bunch of machines (using ssh). The
jobs will need to be run in the following pattern:

(Machine A) (Machine B) (Machine C)

Job A1 Job B1 Job C1

Job A2 Job B2 etc

Job A3 etc

etc

Jobs runing on machine A, B, C should be in parallel, however, for
each machine, jobs should run one after another.

How can I do it with thesubprocess?

Thanks,

JD
