Net* 2.0 or better, that will create performance counters that can be shown in the Perfmon program that is delivered with the Microsoft Windows* OS.

Microsoft's perfmon is capable of showing many useful performance counters on the Windows* OS like disk activity, memory usage, cpu load.

Penryn): it can be enabled by defining PCM_TEST_FALLBACK_TO_ATOM in the As an additional goody, the package includes easy-to-use command line and graphical utilities that are based on these routines.

More information about perfmon for Windows* 7 and Windows* 2008/R2 can be found at here (but perfmon has been available for many releases of Windows now).

Please read the Windows_file on how to install and remove the service for Intel® PCM.

The advances in computer architecture made this algorithm an unreliable metric because of introduction of multi core and multi CPU systems, multi-level caches, non-uniform memory, simultaneous multithreading (SMT), pipelining, out-of-order execution, etc.

Figure 2: The complexity of a modern multi-processor, multi-core system A prominent example is the non-linear CPU utilization on processors with Intel® Hyper-Threading Technology (Intel® HT Technology).

In total, the following metrics are supported: Intel® PCM version 1.5 (and later) also supports Intel® Atom™ processors but counters like memory and Intel® QPI bandwidth and L3 Cache Misses will always show 0 because there is no L3 Cache in the Intel® Atom™ processor and no on-die memory controller or Intel® QPI links.

Intel® PCM version 1.6 supports performance metrics (like instructions per clock cycle, L3 cache misses) of 2nd generation Intel® Core™ processor family (Intel® microarchitecture code name Sandy Bridge) and an experimental support of some earlier Intel® microarchitectures (e.g.Abstraction Level for Performance Monitoring Units The good news is that Intel processors already provide the capability to monitor performance events inside processors.In order to obtain a more precise picture of CPU resource utilization we rely on the dynamic data obtained from the so-called performance monitoring units (PMU) implemented in Intel's processors.For all of the above mentioned hardware counters on the Nehalem and Westmere based platforms, a corresponding perfmon counter is created and therefore all features supported by perfmon are also available for these counters like logging over time in a file or database.For Intel® Atom processors the perfmon counters for memory and Intel® QPI bandwidth and L3 Cache Misses will always show 0 for reasons mentioned above.Contributors (in historical order)Roman Dementiev, Thomas Willhalm, Otto Bruggeman, Patrick Fay, Patrick Ungerer, Austen Ott, Patrick Lu, James Harris, Phil Kerly, Patrick Konsor, Andrey Semin, Michael Kanaly, Ryan Brazones, Rahul Shah, Jacob Dobkins Introduction to Intel® PCM (Performance Counter Monitor)The complexity of computing systems has tremendously increased over the last decades.
