This is very simple and known tip. Query Hint MAXDOP – Maximum Degree Of Parallelism can be set to restrict query to run on a certain CPU. Please note that this query cannot restrict or dictate which CPU to be used, but for sure, it restricts the usage of number of CPUs in a single batch. I have now one question for all readers. Do you use this query hint? If you do use it, then what is the purpose of the same. Please leave a comment here.
