![]() ![]() The focus of processor design has shifted to delivering multiple cores per processor chip and to delivering more hardware threads in each core (known as simultaneous multi-threading (SMT) in IBM Power Architecture® terminology). Trends in processor design are making it more important than ever to invest in improving application performance. It is directed at IBM presales organizations in support of Power Systems products, such as the IBM Power S822 server (Figure 1), and to those responsible for performing migration and implementation activities on IBM POWER8 -based (and earlier) servers. This technical information was developed by IBM domain experts. ![]() ![]() In short, these strategies can maximize the return on your hardware investment. Techniques are also provided for advanced users who have a considerable understanding of application internals. Some of the techniques can be performed without extensive experience. The guidance ranges from simple to complex and is usable across a broad set of IBM POWER® processor chips and systems. These strategies are drawn from performance optimization efforts across many types of code running on IBM AIX®, IBM i, and Linux®. This IBM® Redbooks® Solution Guide describes some of the strategies for optimizing and tuning application code to run on IBM POWER8™ and earlier processor-based systems (IBM Power Systems™). Critical business needs can be met with more assurance in an optimized, well-tuned environment. ![]()
