Identify memory conflicts in a functional-decomposition problem to identify data-restructuring requirements. This procedure is part of the design phase for threaded applications that is necessary in order to identify issues that could cause performance degradation.
Identify the source of performance degradations or low performance gains of applications running on systems that support Hyper-Threading Technology. Once applications have been tuned for the Pentium® 4 processor, they can be tuned for processors that support Hyper-Threading Technology as a separate process. In some cases, however, the tuning process may not yield acceptable increases in performance.
Determine whether performance degradation (or lower-than-expected performance benefit) from Hyper-Threading Technology is due to exceeding the write-combining buffer capacity. A write-combining (WC) store buffer accumulates multiple stores in the same cache line before eventually writing the combined data farther out into the memory hierarchy, to accelerate processor write performance.
We’ve been listening to your feedback on software tuning. Specifically, we’ve been working to make it even easier for developers to analyze software performance on Intel® Microarchitecture Codename Sandy Bridge.
