also, if i remember correctly, openmosix closed their doors earlier this year... --Joe

OSCAR, of course ;)
Seriously, which is better depends entirely on what you are trying to use your
cluster for.
OSCAR, in its default state, creates a beowulf style cluster where programs
running on the cluster are generally specifically designed to run in a
clustered environment. At the least, a bit of script programing is needed to
use an OSCAR cluster. Generally this type of cluster scales very well because
the programs designed to run in this kind of environment are by definition
highly parallel.
OpenMOSIX, or OSCAR using its Single System Image package, which makes all the
cluster nodes and the head node into one large SMP box. Basically this allows
someone to log into the head node and run any program in an environment with
all the memory and CPU power of the entire cluster. This sounds very
appealing, but like with SMP boxes, you don't generally notice a significant
improvement in performance (and often see slow down) because very few programs
are writen to take advantage of multiple processors or large memory
environments.
Now, there are also several other types of environment commonly called
"clusters", including web server clusters and voip clusters, but these are
generally very application specific. OSCAR and OpenMOSIX are not designed with
any particular program in mind, but a broad class of generally scientific
applications.
Hope this helps.

Hi
I have a big question. Which one is better for high performance
computing cluster? OSCAR or OpenMOSIX
Please let me know your ideas.
thanks
