In response to Jeff Layton's article on using the cloud for HPC (link below), there's been a discussion on whether there should be a new term used in this case to replace 'HPC', such as 'research computing' which Jeff used in his articles. I say no. We just need to reconsider how we define HPC. For example, my definition of HPC is as follows, which I often use when giving introductory presentations on HPC.
"High performance computing (HPC) is a form of computer usage where utlilization one of the computer subsystems (processor, ram, disk, network, etc), is at or near 100% capacity for extended periods of time." In this case, extended could be as short as 30 seconds or a few minutes. It's relative, and these day , many CPUs in typical use cases are sitting idle waiting for something to react to (a URL request, mouse movement, or keyboard input, etc.) Using this definition, even 'big data' and cloud jobs described by Jeff are still HPC. It just now the disk/network is at/near 100% instead of the CPU and RAM. That's my opinion on the matter. http://www.admin-magazine.com/HPC/articles/the_cloud_s_role_in_hpc -- Prentice _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
