[Beowulf] top500 clusters using

Not all of the Top500 systems are really HPC systems. Several systems
are basically used for enterprise applications but before moving them
into the "production" environment, the associate vendor run the Linpack
benchmark and submit the system to the list. Check out
http://www.hpcwire.com/features/17905159.html. Somewhat old but still
valid for some cases.

Subject: [Beowulf] top500 clusters using

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 

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 

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