This IBM® Redbooks® publication focuses on gathering the correct technical information, and laying out simple guidance for optimizing code performance on IBM POWER8® processor-based systems that run the IBM AIX®, IBM i, or Linux operating systems. There is straightforward performance optimization that can be performed with a minimum of effort and without extensive previous experience or in-depth knowledge. The POWER8 processor contains many new and important performance features, such as support for eight hardware threads in each core and support for transactional memory. The POWER8 processor is a strict superset of the IBM POWER7+TM processor, and so all of the performance features of the POWER7+ processor, such as multiple page sizes, also appear in the POWER8 processor. Much of the technical information and guidance for optimizing performance on POWER8 processors that is presented in this guide also applies to POWER7+ and earlier processors, except where the guide explicitly indicates that a feature is new in the POWER8 processor. This guide strives to focus on optimizations that tend to be positive across a broad set of IBM POWER® processor chips and systems. Specific guidance is given for the POWER8 processor; however, the general guidance is applicable to the IBM POWER7+, IBM POWER7®, IBM POWER6®, IBM POWER5, and even to earlier processors. This guide is directed at personnel who are responsible for performing migration and implementation activities on POWER8 processor-based systems. This includes system administrators, system architects, network administrators, information architects, and database administrators (DBAs).

Performance Optimization and Tuning Techniques for IBM Power Systems Processors Including IBM POWER8

This morning, Lieutenant Robert “Mac” Macdonald woke up in New York City along with the rest of 8.6 million people, with one goal in mind, serve and protect, and get home in one piece. If he had one single clue that every single truth he held dear to his heart was about to be dismantled. In one single day, a belief system that took decades to refine would be mangled beyond any recognition. However, all was not lost as into his life comes a beautiful woman, far beyond his hopes and dreams, an FBI agent with an incredible secret. They join forces as they tumble down a rabbit hole filled with violence, insanity, and the ancient question of humanity, why are we here. Even in the middle of this tornado, two hearts find each other and ignite a powerful love that just might possibly keep them alive!

The Prophets of Unconquered Sun Spiritual pilgrims, the Zenith Caste of the Solar Exalted are the hands and voice of the Unconquered Sun. Yet these stalwart heroes are more than mere priests and propagandists. With their crusading hearts and invincible strength, the Zenith Caste is a mighty force for righteousness in the world. Those who would make it a place of misery and pain should fear, for the champions of the Sun have come to deliver their comeuppance. The Judges of a New First Age Caste Book: Zenith is the next in the Caste Book series for Exalted -- books detailing the game's different character types. Within its pages are all the secrets of the Zenith Caste, from their fragmentary memories of the First Age to the shared visions of the Unconquered Sun that unite them. The book contains new Charms, rules, spells and artifacts to help them carry out their holy mission.
