They are indeed interesting, but what I find more interesting is that there are more X86
platforms running linux then there are POWER platform running AIX and SPARC platforms running
Linux/Solaris. when looked under "By Processor" from the top tabs" SO, this
makes me ask if POWER and SPARC platforms running AIX and SOLARIS are more superior then x86
platform running Linux, then why are they not being used more to build supercomputers?

I believe reason is simple it is acceptable performace/price ratio for
x86 hardware with regards to math calculations. You would not need all
this visualization support provided by POWER and SPARC hardware and
corresponding to them operating system for HPC. So why pay for something
you wouldn't need?
