eh? blade systems are just tweaks for packaging and cable-management.
I don't believe they have much if any advantage over well-designed
non-blade hardware. or did you mean that both blades and sicortex
are basically boutique approaches, as opposed to fungible/commodity?
I was using the blade example just because of the similarity of having a
stand-alone system with a single power source.
Different paradigms save in the idea that Blades are simply a way to
concentrate heat and make you always come back to one vendor for
additions or replacements. I don't like to lock into a single vendor
unless they're well proven. I've made the blade mistake with a vendor
who, overall, always did the right thing, but having a bunch of blades
did little more than look cool when I needed to expand.
gerry
I know they are not Beowulfs but being distributed
memory machines I figured someone here might have real-world
experience with
one.
I think it's still a beowulf if you apply "the beowulf approach"
(linux and open-source HPC clustering) to non-commodity hardware.
we still have a beowulf of Compaq ES40 alphas, for instance.
Great. I'm glad my post was on topic then. My view is that the SiCortex
machine is not a Beowulf because the term "node" seems to be a chip on
the same board as all of the other nodes. You can't really add nodes
like you could add an ES40 to your Compaq Beowulf. Of course opinions
will vary. I suppose you could add other SiCortex machines... Can you?
Do you have any experience with them? How easy is it to port code to it?
Performance characteristics with certain types of code?
Thanks,
Steve
