Do not confuse "scientific computing" or "high performance computing"
with "cluster". All terms are definitely related, but you can do
scientific/high-perfomance computing without a "cluster."
As someone who also works in life sciences, I know that there are a lot
of life science tasks that are embarrassingly parallel. Running these
tasks on a bunch of different machines simultaneously is definitely
scientific and high performance computing, but it doesn't necessarily
require a cluster. Folding at home, for example.

Me, too, which is why I started ranting about Microsoft's cloud
commercials in a separate thread. ;) It's also why I'm starting to get
picky about how the term "cluster" is used. More and more, I see people
confusing "cloud" with "cluster". I guess that cynicism is what caused
me to reply to the original post.
