Multi-level CMT Scheduling Optimizations

The multi-level Chip Multi-Threaded (CMT) scheduling optimizations feature provides the Solaris kernel with a platform independent mechanism. This mechanism enables discovering and optimizing various performance relevant hardware-sharing relationships existing between CPUs on current and emerging CMT processor architectures, including Niagara II.

This feature also enhances the kernel's thread scheduler or dispatcher with a multilevel CMT load-balancing policy that benefits system performance on various multithreaded, multicore, and multisocket processor-based systems.
