In certain cases, a parallel plan may be chosen even though the query's cost plan is less than the current cost threshold for parallelism value. This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server professional. SELECT (cpu_count / hyperthread_ratio) AS PhysicalCPUs, The following Transact-SQL query can be used for obtaining CPU information for the system. A processor core may contain one or more logical processors. The processor core is the circuitry that provides ability to decode and execute instructions. Each logical processor can execute only one thread context at a time. The max degree of parallelism option is set to 1.ДЄ logical processor is the basic unit of processor hardware that allows the operating system to dispatch a task or execute a thread context. Only a single logical processor is available to SQL Server because of the affinity mask configuration option. Your computer has only one logical processor. SQL Server ignores the cost threshold for parallelism value under the following conditions: Only set cost threshold for parallelism on symmetric multiprocessors. The cost refers to an abstracted unit of cost and not a unit of estimated time. To configure the cost threshold for parallelism option, using:ДЇollow Up: After you configure the cost threshold for parallelism optionД«efore You Begin Limitations and Restrictions The cost threshold for parallelism option can be set to any value from 0 through 32767. The cost refers to an estimated cost required to run the serial plan on a specific hardware configuration, and is not a unit of time. SQL Server creates and runs a parallel plan for a query only when the estimated cost to run a serial plan for the same query is higher than the value set in cost threshold for parallelism. The cost threshold for parallelism option specifies the threshold at which SQL Server creates and runs parallel plans for queries.
