======Glossary======
=====High Performance Computing=====
  * The use of parallel processing for running advanced application programs efficiently, reliably and quickly.

=====Supercomputer=====
  * A system that performs at or near the currently highest operational rate for computers. Some supercomputers work at over half a petaflop or 10<sup>15</sup> floating-point operations per second.
=====FLOPS=====
  * Number of floating point operations per second
=====Peak Performance=====
  * Peak Flops, the theoretical measure of floating point potential
=====Sustained Performance=====
  * Currently, as measured by LinPack (http://www.top500.org)
=====HPI=====
  * High Performance Interconnect
  * This usually means Infiniband
=====Grid=====
  * Originally born out of high performance computing
  * Enhancing the capability of the network of things rather than making applications run faster
=====Cluster=====
  * Group of tightly coupled (usually with a high performance interconnect) computers that work together
=====Beowulf Cluster=====
  * Commodity based cluster COTS (commodity-off-the-shelf) components
  * Linux, Intel/AMD
=====Compute Farm=====
  * Loosely coupled cluster (no high performance interconnect)
=====Single Precision=====
  * 32 bits
  * Significand of 24 bits
  * Exponent of 7 bits
  * 1 sign bit
=====Double Precision=====
  * 64 bits
  * Significand of 52 bits
  * Exponent of 11 bits
  * 1 sign bit
