Abstract: According to one embodiment, a processor includes an execution pipeline for executing a plurality of threads, including a first thread and a second thread. The processor further includes a multi-thread controller (MTC) coupled to the execution pipeline to determine whether to switch threads between the first and second thread based on a thread switch policy that is selected from a list of thread switch policies based on unfairness levels of the first and second thread, and in response to determining to switch threads, to switch from executing the first thread to executing the second thread.

Abstract: In an embodiment of the invention, a method for dynamic hardware multithreading, includes: using a hardware halt function or a hardware yield function in a processor core in order to enable or disable a hardware thread that shares the core; wherein the hardware thread is disabled by placing the hardware thread in a halt state or yield state, and allowing another hardware thread to utilize the core.

Abstract: Systems, methodologies, media, and other embodiments associated with mitigating the effects of context switch cache and TLB misses are described. One exemplary system embodiment includes a processor configured to run a multiprocessing, virtual memory operating system. The processor may be operably connected to a memory and may include a cache and a translation lookaside buffer (TLB) configured to store TLB entries. The exemplary system may include a context control logic configured to selectively copy data from the TLB to the data store for a first process being swapped out of the processor and to selectively copy data from the data store to the TLB for a second process being swapped into to the processor.

Abstract: Systems, methodologies, computer-readable media, and other embodiments associated with ordering instructions are described. One exemplary system embodiment can include an analysis logic configured to analyze executable instructions from an executable program. A re-write logic can be configured to re-order selected load instructions within the executable program based on latency times for the selected load instructions.

Abstract: Systems, methodologies, media, and other embodiments associated with acquiring instruction addresses associated with performance monitoring events are described. One exemplary system embodiment includes logic for recording instruction and state data associated with events countable by performance monitoring logic associated with a pipelined processor. The exemplary system embodiment may also include logic for traversing the instruction and state data on a cycle count basis. The exemplary system may also include logic for traversing the instruction and state data on a retirement count basis.
