Technique for dynamically restricting thread concurrency without rewriting thread code

摘要

A method for executing uniprocessor (UP) coded workloads in a computer capable of concurrent thread execution is disclosed. The method identifies threads in the uniprocessor coded workloads (UP-workloads) which can execute concurrently, and identifies threads in the UP-workloads which cannot execute concurrently. First threads which cannot execute concurrently are assigned to a first concurrency group. Second threads which cannot execute concurrently are assigned to a second concurrency group. Any thread in the first concurrency group can execute concurrently with any thread in the second concurrency group. The computer capable of concurrent thread execution then executes the UP-coded workloads in the first concurrency group at substantially the same time as executing the UP-coded workloads in the second concurrency group.
