[Beowulf] top500 clusters using

[Mikhail Kuzminsky]

Last top500 lists contain a set of sites which are not from HPC world.
I understand that there may be parallelized applications which may use 
whole cluster for one task, but this task isn't floating-point 
oriented.

But (in top500) there is a set of "unnamed" sites like "IT service 
provider" etc. IMHO they may use clusters for Web-hosting etc, where 
may be load balancing is used. I.e. it's not "supercomputer" (I means 
computer, all CPUs/cores of which may be used for solving of one 
task).

Am I right - or they really work w/applications, which may involve 
whole cluster for one task solving ?
