bandwidth test, it exercises both of these modes of operation. The test serves as a latency sensitive test case when the test threads perform
Additionally, the tests are run in undersubscribed, highly subscribed, and fully subscribed modes. In undersubscribed mode, there are significantly fewer threads than the number of processors. In highly subscribed mode, the number of threads approaches the number of processors. In the fully subscribed mode, the number of threads is equal to the number of processors. Testing these conditions provides an understanding of the impact of thread subscription on performance.
Based on the data and the analysis gathered from this synthetic
