Solaris Operating System - Version 10 and later Information in this document applies to any platform.
Chip Multi-threading refers to the family of processor technologies that allow a physical processor to simultaneously execute multiple threads of execution. It is the core of a processor that executes application instructions. A CMT physical processor can have multiple cores in it where each core is capable of running multiple threads (instructions from multiple streams). These hardware threads are seen by Solaris as a separate CPU.
Objective of this article is to describe features of Chip Multi-threaded Processors and how to monitor performance of workload running on these type of processors.
