Adam Machanic Surfing the Multicore Wave Processors Parallelism and Performance

5/17/2013 8:45 AM - 4:45 PM

Surfing the Multicore Wave: Processors, Parallelism, and Performance

Today's server hardware ships with a truly massive amount of CPU power. And while SQL Server is designed to automatically and seamlessly take advantage of available processing resources, there are a number of options, settings, and patterns that can be exploited to optimize parallel processing of your data. This full-day seminar starts with an overview of CPU scheduler internals from the perspective of both Windows and the SQL Server Operating System (SQLOS). Next, you will learn about intra-query parallelism, the method that SQL Server uses to break up large tasks into many smaller pieces, so that each piece can be processed simultaneously. You will come to understand how to read parallel query plans and how to interpret parallel wait statistics, as well as best practices for the various parallelism settings within SQL Server. Finally, you will be introduced to techniques for exploiting parallelism at the query level: patterns that can help the optimizer do a better job of parallelizing your query. After attending this seminar, you will be in full control of your CPUs, able to compel your server to use every clock tick to your end users' advantage.

This session is intended for mid-level to advanced DBAs and DB developers.
