Click the 
Calculate Algorithm button in the Start Calculation group on the Calculation ribbon tab.
Press F5.
Algorithm calculation order:
Set calculation dates and parameter values on the parameters panel.
Select the Multithreaded Calculation checkbox in the Set Up Calculation Execution group on the Calculation ribbon tab to speed up calculation of calculation blocks and control blocks if the Multithreaded Calculation checkbox is selected in the calculation block or control block editing wizard. Aggregation blocks are calculated only using multithreaded calculation.
NOTE. Checkbox state is active only during algorithm calculation.
Execute the entire algorithm or its blocks.
By default, calculation results are automatically saved.
To calculate the entire algorithm:
Click the Calculate Algorithm button in the Start Calculation group on the Calculation ribbon tab.
Press F5.
Algorithm calculation is started. To stop algorithm calculation, click the 
Stop button in the Start Calculation group on the Calculation ribbon tab.
TIP. If you want to deny algorithm calculation stop, see the How to Deny Calculation Algorithm Stop? section.
During calculation, all algorithm objects can be read. For example, the user can check calculation block settings or open block calculation results in the Analytical Queries (OLAP) tool.
After the calculation is completed, the dialog box containing results opens. For example:
If an error occurred on calculation, the corresponding message is displayed.
To calculate only selected blocks:
Select the blocks to be calculated in the working area or calculation tree.
To select several blocks in the working area, use the SHIFT key, in the calculation tree - the CTRL or SHIFT key.
Click the 
Calculate Selected button in the Start Calculation group on the Calculation ribbon tab.
After the calculation is completed, the dialog box containing results opens. If an error occurred on calculation, the corresponding message is displayed.
To calculate without saving data:
Select the Do not Save Result to Database checkbox in the Set Up Calculation Execution group on the Calculation ribbon tab.
Execute the entire algorithm or its blocks.
