My own (vague) definition of HPC would probably be based more on the<br>
intended design of the system, something like:<br>
<br>
"A high-performance computing system is designed to use one or more<br>
computers to achieve the maximum performance possible on a particular<br>
computational task."<br>
<br>
This could be improved, but it makes a distinction between maxing out a<br>
"normal" computer and designing a system specifically for performance.<br></blockquote><div><br></div><div style>The definition I use is:</div><div style>A Computational task that requires combining the performance of multiple systems to achieve results faster than a single system. The key requirement is the aggregation of hardware resources (CPU, Memory, Disk, Networking, etc) beyond a single "box" whether under a single OS instance like ScaleMP/SMP or multiple OS/s using MPI and other methods of managing the distribution of tasks.</div>
<div style><br></div><div style>This should be easily distinguishable from Enterprise computing tasks which often can make due with a fraction of a system to complete its designated task, enabling the virtualization technologies to thrive. Multiple systems are used typically for High Availability rather than High Performance in Enterprise computing.</div>
<div style><br></div><div style>The "task" still needs to be defined, perhaps as a "computational task", to distinguish it from farms of email servers that may well churn at 100% utilization at peak times. Of course, email looks more and more like a big data / big compute problem every day when hiding spam and virus protection tasks are taken into account.</div>
