very basic cluster question

["Tracy Zhao" <TZhao@CELGENE.com>]

Hi,
I have a very basic cluster question and I would be very amazed if anyone
responded to my question becuase it's really beyond basic.

Here is my question:

	I am trying to build a cluster and I've been trying to decide
between building a Scyld Beowulf cluster and a Rocks cluster.
I have been trying to find documentation everywhere for the differences
between the two but I haven't been very sucessful.
	I've heard that the Scyld Beowolf cluster would give you a Single
System Image which is cleaner than the set up of a Rocks cluster.
I've even heard Rocks clusters being comparable to having a bunch of
computers on a network and just writing code to delegate jobs to each
machine.
Could you tell me where I can find some basic information as to the
differences between these clusters and how it would be beneficial to have a
Rocks cluster vs. 
a bunch of machines on a network? And how about having a database running on
a cluster? 
	Sorry about these basic questions but I'm really lost as to where I
can find this type of basic, before you start building a cluster type of
information.

		Thanks,
		Tracy Zhao
