Today CPU have many-core architecture and a sets of enhanced instructions. For example, latest IBM POWER processor family has advanced cache states for effective coherence management, vector-scalar extension (VSX) and decimal floating point (DFP) instructions. Advanced Toolchain 5 (AT5), optimized and provided for Linux PPC64 platform, can help your development using these latest CPU features and accelerate your applications on Linux. This presentation introduces an overview, how to use and effectiveness of AT5 through several examples of adaption, and also explains that Linux can easily leverage hardware capability, attract more developers to Linux and expand Linux eco-system.
