Lenovo‘s Cool Fix for HPC Energy Consumption

High performance computing (HPC) and supercomputing haven’t always been closely associated with energy efficiency. In fact, for the first four decades (beginning in the early 1960s) of commercial supercomputing, owners were far more concerned with systems’ computational capabilities than the electrical energy they consumed. That was mainly because of the unique value of custom-built systems like the Cray CDC 6600 (delivered in 1964)...

Will ARM Face a Cold Shoulder in the Data Center?

Over the past couple of years, there has been rising interest in and considerable promotion of servers and appliances based on the ARM microprocessor architecture. At first glance, the narrative makes some sense. ARM’s native performance and energy efficiency, when multiplied across hundreds or thousands of systems, looks effective for supporting certain kinds of workloads common in Web 2.0, social networking and search sites. That is...
