## 26 Using Parallel Calculation

Essbase parallel calculation lets you streamline calculations by running them as concurrent, independent tasks.

With serial calculation, each calculation pass is scheduled to run on a single processor. If invoked from a calculation script, the calculations are executed sequentially in the order in which they appear in the calculation script. Parallel calculation breaks each calculation pass into sub-tasks. The sub-tasks that can run independently of one another are scheduled to run simultaneously on up 128 threads. Each thread may be on a different processor.
