If my understanding is correct, Beowulf is clustering of multiple
boxes into one “super-machine”.
The QNX native networking model actually treats a multi-node network
as one logical machine. (Its not quite that – the networking is
essentially transparent, but it doesn’t have any sort of transparent
load-balancing or process migration from one machine to another.)

I have something that might be what you need in a pinch – it’s a distributed
batch queue system for QNX 4, modeled (loosely) after VAX/VMS batch queues 
For example, you can put stuff onto the queue like this:
dq submit mp3_encode -b192 spud1.wav
dq submit mp3_encode -b192 spud2.wav
dq submit mp3_encode -b192 spud3.wav
dq submit mp3_encode -b192 spud4.wav
This would put four jobs on the batch queue, and then the available CPUs on the
network would ask for work from the central server.
I said “in a pinch” because right now the source depends on a few things – it
assumes that the only user is root, there are no priorities within the batch
queues, yaddy yaddy yaddy – but it’s useful for what I’m doing with it (raytrace,
midi-to-wav conversions, mp3_encodes, etc).

FYI, my implementation is the classical “reply-driven” model, where the worker nodes
“report in” for work to the master node. I love message passing

Wanted PDP-8/9/10/11/12 Systems/documentation/spare parts! Will trade books!
It seems grate !
But I haven´t got a QNX 4 license to use in my MP3 web site->
www.prosom.com.br …
We already use m_queues in some process controls. I will try it in //
processing.
Thanks !
