# Load Generator

**Misc/Load Generator**

The Load Generator is an operator for simulating load on the CPU and GPU. This can be useful for stress-testing a project or a server. The Load Generator Operator is rarely used, but in some cases, it can be useful.

- **Frequency**
  - **Load frequency** - How often the load should be applied.
  - **Last load rendered** - Last time the load was applied.
- **CPU**
  - **Computer sleep time (1 tread)**- Generates a "sleep" of x milliseconds on the main rendering CPU thread.
  - **CPU Threads** - How many CPU threads to spawn (except for the main rendering thread).
  - **CPU Load per thread** - How much workload to apply on each CPU thread.
- **GPU**
  - **GPU Load per thread** - Number of CUDA kernels to launch per CPU core.
  - **GPU run in parallel** - Toggle on/off. Allow the GPU work (threads) to be spawned in parallel.
- **About**
  - Information about the operator.
