Hello,
I'm planning on implementing some method to ensure that random number streams
generated on different nodes of a cluster are independent of one another.
This is important for problems such as Monte Carlo. Before I start, I'd like
to hear advice, suggestions, requests. Thanks, Michael

If your platform as /dev/urandom, then the octave-forge random
generators will use it to seed the generators, and you will end up with
independent number streams. Even if you don't have /dev/urandom, then
these generators use the LSB of the clock to seed with (ie. usec) and so
you'll probably find yourself with independent streams in any case.
So my advice is to use the octave-forge generators...
