"High Performance Computing" ou
"Calcul Haute Performances"
High-Performance Computing (HPC) refers to any form of computing where the density of processing or the size of the problems addressed require more than a standard or commodity computing system in order to achieve the expected result under the given constraints, and the application of advanced techniques such as the use of multiple processors (tens, hundreds, thousands or even more) connected together by some kind of network to achieve a performance well above that of a single processor.
Both projects began in 1993, with significant systems deployed in 1994,
and both had strong impact on the community, essentially defining the
range of capabilities and techniques to be incorporated to this day.

"High Performance Computing" ou
"Calcul Haute Performances"
The term “HPC” is very easy : it stands for high-performance
computing (or “computer” depending on context), but the definition of what is “high-performance” is vague, relative and almost constantly changing as hardware continues to improve.
It is a characteristic feature that today’s workstations now offer levels of performance (or better) than only three-five years ago required extremely expensive HPC hardware in the form of vector supercomputers.
