Thread: Microsoft consequences Hotfix for AMD Bulldozer Processors

As the telling goes, 'If at first you do not succeed, acquire your material both and roll out another hotfix already, it is 2012!' Might be the saying does not go perfectly similar to that, but it should if you are speaking about the combination of Microsoft Windows and AMD's Bulldozer line. Later pushing out a Bulldozer-boosting hotfix in mid-December, the Redmond software giant pulled it offline a some days after at the request of AMD, which named the patch "incomplete." Just it is back and it has the complete blessing of the Santa Clara chip maker.


"Recently, the central processing unit programing methods utilized through Windows Server 2008 R2 SP1 are not optimized for the example architecture of the AMD Opteron 6200 and 4200 Serial processors," AMD told in a blog post.



"This means that sure multi-threaded workloads will not be optimally distributed among cores, which can answers in reduced system function.


"Microsoft has now posted a hotfix for Windows Server 2008 R2 SP1 attested in KB2645595 that enlightens the OS kernel to the AMD Opteron 6200 and 4200 Serial topology so that the kernel can do a excellent job of programing threads to the processor cores. This patch leverages function that AMD and Microsoft have finish cooperatively for future editions of the Windows kernel, and can be used as desired through users functioning Windows Server 2008 R2 SP1."


The patches too use to Windows 7, not only Windows Server 2008 R2. Consorting to AMD, later using the inform, your OS will be 'enlightened' to the ways of Opteron 6200 and 4200 Serial topology, permitting the kernel to do an excellent job of programing threads to the processor cores. It is not probably to affect legacy apps too much, but could give a boost to workloads that are fairly threaded, such as virtualization, database, or transactional environments, AMD says.
