He might not be doing capacity planning, but, rather, writing a press release.
Friday the 13th, 2013, Elbonia Acme SuperComputing announced their latest Beowulf cluster based on the legendary IBM model 5150. With over 8 million bytes of read write memory distributed across its 16 computing nodes, the cluster is capable of a nearly a million integer 16x16 multiplication operations per second. Acme expects to announce an enhanced version that includes 760 kilobytes of removable magnetic disk storage in each node, as well as a floating point co-processor bringing the peak performance to nearly 800,000 Floating Point operations per second (0.8 MFLOPS).
