You may refer to [Launch Colossal-AI](./launch_colossalai.md) for more details.
## Tensor Parallel Micro-Benchmarking
As Colossal-AI provides an array of tensor parallelism methods, it is not intuitive to choose one for your hardware and
model. Therefore, we provide a simple benchmarking to evaluate the performance of various tensor parallelisms on your system.
This benchmarking is run on a simple MLP model where the input data is of the shape `(batch_size, seq_length, hidden_size)`.
Based on the number of GPUs, the CLI will look for all possible tensor parallel configurations and display the benchmarking results.
You can customize the benchmarking configurations by checking out `colossalai benchmark --help`.
```shell
# run on 4 GPUs
colossalai benchmark --gpus 4
# run on 8 GPUs
colossalai benchmark --gpus 8
```
:::caution
Only single-node benchmarking is supported currently.
