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.
