Didn't we hash through this a few years ago, too? I seem to recall a
similar definition, but one that specifically indicated that shared
memory wasn't an element of a Beowulf Cluster? Didn't that make it into
Kragen's FAQ?

My short operational definition of a cluster is collection of
independent systems (motherboards) that communicate
over a private network/interconnect, none of which
are dependent on the other for operating, with
excetion of the head/master/gateway node.
Under this definition, a multi-core node is not a cluster
nor is any design whose operation is dependent
upon shared memory between nodes, even though the
nodes are separate systems. Of course this is my
definition.
BTW, I believe the following is also used:
N=nodes
P=cores/processors per node
P>=N = cluster
N<P = constellation

Hi,
I am kinda confused with term cluster and now am sure if this where I can
post my question. What exactly can be defined as a cluster ?, We have a 32
node cluster in our lab. and the number 32 here is referred to 32 separate
machines ( each with its own processor ). What about the new machines
like,
dual core processors or the quad core processors, are those considered
clusters also. For example, should we refer to a quad core processor as a
cluster of 4 processors. Hope someone out there could explain. Thanks
