-====Glossary====+======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
