I said something similar to the above, but with two important differences: I said hardware “threads,” not only hardware “cores” – it was about the amount of hardware parallelism available on a mainstream system. Longer answer follows: Here’s the main part from article, “Design for Manycore Systems” (August 11, 2009).

SQL Server asks the CPU if it supports SSE or AVX in order to determine the level of hardware support present on the system. Windows 2012 R2 and newer releases have been enlightened the Crypto* APIs. This post will outline SQL Server’s decisions around SSE/AVX or software algorithm use. Reference APIs such as: CryptDecrypt.

The predominant desktop situation is relatively straightforward: Browsers handle links, and non-browsers defer loading http and https URLs to the system, which in turn invokes the default browser. Instead, they load content referred by their hosting native app in system-provided WebViews. Hardware access APIs, notably: Geolocation.

Now welcome to the hardware jungle. 2012 will see us continue to build out multicore with mainstream quad- and eight-core tablets (as Windows 8 brings a modern tablet experience to x86 as well as ARM), and the last single-core gaming console holdout will go multicore (as Nintendo’s Wii U replaces Wii).

I always check backups first when looking at a new system. Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes.

Your NUMA system may not have different processor groups for each node. Here is another example from another two node system I have with one processor group.

More than a decade ago, Amazon embarked on a mission to build a distributed system that challenged conventional methods of data storage and querying. In 2012, we launched Amazon DynamoDB, the successor to Amazon Dynamo. Let’s now look at the history behind the service and the context for new innovations that make me think that.
