Tech Corner Programming, systems operations and more Built for Speed and Performance From silicon to architecture, zEC12 innovations push the envelope By C. Kevin Shum and Charles Webb T he IBM mainframe has long been the platform of choice for enterprise computing. With IBM System z* leadership, its virtualization and workloadmanagement capabilities deliver the highest level of operational efficiency and system utilization. EC12 (zEC12) was developed to extend its base features, adding more innovations to yield an even better platform for critical information systems. The key to extending zEnterprise leadership performance lies in leveraging the scalability of various technologies to keep up with the growing scale and scope of enterprise computing workloads. For the zEC12, these scaling factors include more: Transistors per chip Instructions processed in parallel from the processor pipeline design Processors per book, multichip modules and cooling technologies Efficient software scaling to utilize those processors, aided by extensions to the z/Architecture* instruction set In addition, it’s considered a highly secure and reliable machine. Each generation incorporates the latest innovations from a talented pool of researchers, architects, software programmers and hardware engineers, utilizing the full range of IBM technology, from silicon chips to multisystem ensembles. When announced in 2010, the zEnterprise* System processor core not only ran at 5.2 GHz—the world’s fastest at the time—but also included an impressive list of innovations. A new, out-of-order instruction-processing pipeline was implemented to allow overlapping instruction executions and cache misses, thus speeding up applications. A new on-chip cache hierarchy also reduced effective memory access time, further benefiting memoryintensive applications. New instructions enabled compilers to generate more efficient code for applications and middleware. As the successor to the zEnterprise 196 (z196), the zEnterprise Technology Usages Basic enablements for hardware improvements start with chipmaking.
