Low Power Amdahl Blades for Data Intensive Computing

In Microslice Servers and the Case for Low-Cost, Low-Power Servers, I observed that CPU bandwidth is outstripping memory bandwidth. Server designers can address this by: 1) designing better memory subsystems or 2) reducing the CPU per-server. Optimizing for work done per dollar and work done per joule argues strongly for the second approach for many…
