The summary I usually give goes something like this: IF your computation takes too long on a single system AND you can split the work up into a lot of smaller pieces AND the work is batch oriented AND what you are doing involves a lot of data THEN you should consider trying it out. There are other systems for scalable computing (for example Gridgain) that may be better in other situations. HTH -- Met vriendelijke groeten, Niels Basjes
