# Parallel Gateways Example
|
|
|
|
## Overview
|
|
|
|
This example illustrates the use of parallel gateways in BPMN models to manage and synchronize concurrent tasks effectively.
|
|
|
|
Parallel gateways are powerful BPMN elements that split a process flow into multiple independent flows, allowing for the simultaneous execution of tasks, and later merging these flows to ensure coordination before moving forward.
|
|
|
|
### Process Steps
|
|
|
|
|
|
1. **Parallel Gateway (Split)**: After the start event, the gateway divides the main flow into two separate paths, enabling tasks to be processed in parallel.
|
|
|
|
2. **Sequence Flow 1: Script Task [y = 1]**: Assigns the value `1` to variable `y`. This script task initializes variable `y` and demonstrates setting a simple variable in one branch of the parallel flow.
|
|
|
|
3. **Sequence Flow 2: Script Task [z = 2]**: Similar to the first script task, this operation assigns the value `2` to variable `z`. It functions concurrently with the first script task, demonstrating the capability of the BPMN model to handle multiple operations at the same time.
|
|
|
|
4. **Parallel Gateway (Merge)**: This merging gateway reunites the divergent paths after independent task completion, ensuring all parallel processes are complete before moving forward. It acts as a critical checkpoint in the process to synchronize and consolidate data from multiple sources, ensuring that no task moves forward until all parallel tasks have concluded.
|
|
|
|
5. **Script Task [x = y + z]**: Computes the sum of `y` and `z` and assigns it to variable `x`.
|
|
- **Script**: `x = y + z`
|
|
- This script task demonstrates the aggregation or combination of results from parallel tasks, highlighting how data from independent branches can be combined.
|
|
|
|
After the script task, signal the successful completion of the process with the End Event.

|
|
|
**Output**:
|
|
After running the task, it will compute and show the result:
