### Simple, Flexible Experiment Orchestration

**The ClearML Agent was built to address the DL/ML R&D DevOps needs:**

* Easily add & remove machines from the cluster
* Reuse machines without the need for any dedicated containers or images
* **Combine GPU resources across any cloud and on-prem**
* **No need for yaml / json / template configuration of any kind**
* **User friendly UI**
* Manageable resource allocation that can be used by researchers and engineers
* Flexible and controllable scheduler with priority support
* Automatic instance spinning in the cloud

**Using the ClearML Agent, you can now set up a dynamic cluster with \*epsilon DevOps**

*epsilon - Because we are :triangular_ruler: and nothing is really zero work

### Kubernetes Integration (Optional)

We think Kubernetes is awesome, but it is not a must to get started with remote execution agents and cluster management.
We designed `clearml-agent` so you can run both bare-metal and on top of Kubernetes, in any combination that fits your environment.

You can find the Dockerfiles in the [docker folder](./docker) and the helm Chart in https://github.com/allegroai/clearml-helm-charts

#### Benefits of integrating existing Kubernetes cluster with ClearML

- ClearML-Agent adds the missing scheduling capabilities to your Kubernetes cluster
- Users do not need to have direct Kubernetes access!
- Easy learning curve with UI and CLI requiring no DevOps knowledge from end users
- Unlike other solutions, ClearML-Agents work in tandem with other customers of your Kubernetes cluster
- Allows for more flexible automation from code, building pipelines and visibility
- A programmatic interface for easy CI/CD workflows, enabling GitOps to trigger jobs inside your cluster
- Seamless integration with the ClearML ML/DL/GenAI experiment manager
- Web UI for customization, scheduling & prioritization of jobs
- **Enterprise Features**: RBAC, vault, multi-tenancy, scheduler, quota management, fractional GPU support

**Run the agent in Kubernetes Glue mode an map ClearML jobs directly to K8s jobs:**
- Use the [ClearML Agent Helm Chart](https://github.com/allegroai/clearml-helm-charts/tree/main/charts/clearml-agent) to spin an agent pod acting as a controller
- Or run the [clearml-k8s glue](https://github.com/allegroai/clearml-agent/blob/master/examples/k8s_glue_example.py) on
a Kubernetes cpu node
- The clearml-k8s glue pulls jobs from the ClearML job execution queue and prepares a Kubernetes job (based on provided
yaml template)
- Inside each pod the clearml-agent will install the job (experiment) environment and spin and monitor the
experiment's process, fully visible in the clearml UI
- Benefits: Kubernetes full view of all running jobs in the system
- **Enterprise Features**
- Full scheduler features added on Top of Kubernetes, with quota/over-quota management, priorities and order.
- Fractional GPU support, allowing multiple isolated containers sharing the same GPU with memory/compute limit per container

### SLURM (Optional)

Yes! Slurm integration is available, check the [documentation](https://clear.ml/docs/latest/docs/clearml_agent/#slurm) for further details

### Using the ClearML Agent

**Full scale HPC with a click of a button**

The ClearML Agent is a job scheduler that listens on job queue(s), pulls jobs, sets the job environments, executes the
job and monitors its progress.

Any 'Draft' experiment can be scheduled for execution by a ClearML agent.

A previously run experiment can be put into 'Draft' state by either of two methods:

* Using the **'Reset'** action from the experiment right-click context menu in the ClearML UI - This will clear any
results and artifacts the previous run had created.
* Using the **'Clone'** action from the experiment right-click context menu in the ClearML UI - This will create a new
'Draft' experiment with the same configuration as the original experiment.

An experiment is scheduled for execution using the **'Enqueue'** action from the experiment right-click context menu in
the ClearML UI and selecting the execution queue.

See [creating an experiment and enqueuing it for execution](#from-scratch).

Once an experiment is enqueued, it will be picked up and executed by a ClearML Agent monitoring this queue.

The ClearML UI Workers & Queues page provides ongoing execution information:

- Workers Tab: Monitor you cluster
- Review available resources
- Monitor machines statistics (CPU / GPU / Disk / Network)
- Queues Tab:
- Control the scheduling order of jobs
- Cancel or abort job execution
- Move jobs between execution queues

#### What The ClearML Agent Actually Does

The ClearML Agent executes experiments using the following process:

- Create a new virtual environment (or launch the selected docker image)
- Clone the code into the virtual-environment (or inside the docker)
- Install python packages based on the package requirements listed for the experiment
- Special note for PyTorch: The ClearML Agent will automatically select the torch packages based on the CUDA_VERSION
environment variable of the machine
- Execute the code, while monitoring the process
- Log all stdout/stderr in the ClearML UI, including the cloning and installation process, for easy debugging
- Monitor the execution and allow you to manually abort the job using the ClearML UI (or, in the unfortunate case of a
code crash, catch the error and signal the experiment has failed)

#### System Design & Flow

clearml-architecture

#### Installing the ClearML Agent

```bash
pip install clearml-agent
```

#### ClearML Agent Usage Examples

Full Interface and capabilities are available with

```bash
clearml-agent --help
clearml-agent daemon --help
```

#### Configuring the ClearML Agent

```bash
clearml-agent init
```

Note: The ClearML Agent uses a cache folder to cache pip packages, apt packages and cloned repositories. The default
ClearML Agent cache folder is `~/.clearml`.

See full details in your configuration file at `~/clearml.conf`.

Note: The **ClearML Agent** extends the **ClearML** configuration file `~/clearml.conf`.
They are designed to share the same configuration file, see example [here](docs/clearml.conf)

#### Running the ClearML Agent

For debug and experimentation, start the ClearML agent in `foreground` mode, where all the output is printed to screen:

```bash
clearml-agent daemon --queue default --foreground
```

For actual service mode, all the stdout will be stored automatically into a temporary file (no need to pipe).
Notice: with `--detached` flag, the *clearml-agent* will be running in the background

```bash
clearml-agent daemon --detached --queue default
```

GPU allocation is controlled via the standard OS environment `NVIDIA_VISIBLE_DEVICES` or `--gpus` flag (or disabled
with `--cpu-only`).

If no flag is set, and `NVIDIA_VISIBLE_DEVICES` variable doesn't exist, all GPUs will be allocated for
the `clearml-agent`.

If `--cpu-only` flag is set, or `NVIDIA_VISIBLE_DEVICES="none"`, no gpu will be allocated for
the `clearml-agent`.

Example: spin two agents, one per GPU on the same machine:

Notice: with `--detached` flag, the *clearml-agent* will run in the background

```bash
clearml-agent daemon --detached --gpus 0 --queue default
clearml-agent daemon --detached --gpus 1 --queue default
```

Example: spin two agents, pulling from dedicated `dual_gpu` queue, two GPUs per agent

```bash
clearml-agent daemon --detached --gpus 0,1 --queue dual_gpu
clearml-agent daemon --detached --gpus 2,3 --queue dual_gpu
```

##### Starting the ClearML Agent in docker mode

For debug and experimentation, start the ClearML agent in `foreground` mode, where all the output is printed to screen

```bash
clearml-agent daemon --queue default --docker --foreground
```

For actual service mode, all the stdout will be stored automatically into a file (no need to pipe).
Notice: with `--detached` flag, the *clearml-agent* will run in the background

```bash
clearml-agent daemon --detached --queue default --docker
```

Example: spin two agents, one per gpu on the same machine, with default `nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04`
docker:

```bash
clearml-agent daemon --detached --gpus 0 --queue default --docker nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04
clearml-agent daemon --detached --gpus 1 --queue default --docker nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04
```

Example: spin two agents, pulling from dedicated `dual_gpu` queue, two GPUs per agent, with default
`nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04` docker:

```bash
clearml-agent daemon --detached --gpus 0,1 --queue dual_gpu --docker nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04
clearml-agent daemon --detached --gpus 2,3 --queue dual_gpu --docker nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04
```

##### Starting the ClearML Agent - Priority Queues

Priority Queues are also supported, example use case:

High priority queue: `important_jobs`, low priority queue: `default`

```bash
clearml-agent daemon --queue important_jobs default
```

The **ClearML Agent** will first try to pull jobs from the `important_jobs` queue, and only if it is empty, the agent
will try to pull from the `default` queue.

Adding queues, managing job order within a queue, and moving jobs between queues, is available using the Web UI, see
example on our [free server](https://app.clear.ml/workers-and-queues/queues)

##### Stopping the ClearML Agent

To stop a **ClearML Agent** running in the background, run the same command line used to start the agent with `--stop`
appended. For example, to stop the first of the above shown same machine, single gpu agents:

```bash
clearml-agent daemon --detached --gpus 0 --queue default --docker nvidia/cuda:11.0.3-cudnn8-runtime-ubuntu20.04 --stop
```

### How do I create an experiment on the ClearML Server?

* Integrate [ClearML](https://github.com/allegroai/clearml) with your code
* Execute the code on your machine (Manually / PyCharm / Jupyter Notebook)
* As your code is running, **ClearML** creates an experiment logging all the necessary execution information:
- Git repository link and commit ID (or an entire jupyter notebook)
- Git diff (we’re not saying you never commit and push, but still...)
- Python packages used by your code (including specific versions used)
- Hyperparameters
- Input artifacts

You now have a 'template' of your experiment with everything required for automated execution

* In the ClearML UI, right-click on the experiment and select 'clone'. A copy of your experiment will be created.
* You now have a new draft experiment cloned from your original experiment, feel free to edit it
- Change the hyperparameters
- Switch to the latest code base of the repository
- Update package versions
- Select a specific docker image to run in (see docker execution mode section)
- Or simply change nothing to run the same experiment again...
* Schedule the newly created experiment for execution: right-click the experiment and select 'enqueue'

### ClearML-Agent Services Mode

ClearML-Agent Services is a special mode of ClearML-Agent that provides the ability to launch long-lasting jobs that
previously had to be executed on local / dedicated machines. It allows a single agent to launch multiple dockers (Tasks)
for different use cases:
* Auto-scaler service (spinning instances when the need arises and the budget allows)
* Controllers (Implementing pipelines and more sophisticated DevOps logic)
* Optimizer (such as Hyperparameter Optimization or sweeping)
* Application (such as interactive Bokeh apps for increased data transparency)

ClearML-Agent Services mode will spin **any** task enqueued into the specified queue. Every task launched by
ClearML-Agent Services will be registered as a new node in the system, providing tracking and transparency capabilities.
Currently, clearml-agent in services-mode supports CPU only configuration. ClearML-Agent services mode can be launched
alongside GPU agents.

```bash
clearml-agent daemon --services-mode --detached --queue services --create-queue --docker ubuntu:18.04 --cpu-only
```

**Note**: It is the user's responsibility to make sure the proper tasks are pushed into the specified queue.

### AutoML and Orchestration Pipelines

The ClearML Agent can also be used to implement AutoML orchestration and Experiment Pipelines in conjunction with the
ClearML package.

Sample AutoML & Orchestration examples can be found in the
ClearML [example/automation](https://github.com/allegroai/clearml/tree/master/examples/automation) folder.

AutoML examples:

- [Toy Keras training experiment](https://github.com/allegroai/clearml/blob/master/examples/optimization/hyper-parameter-optimization/base_template_keras_simple.py)
- In order to create an experiment-template in the system, this code must be executed once manually
- [Random Search over the above Keras experiment-template](https://github.com/allegroai/clearml/blob/master/examples/automation/manual_random_param_search_example.py)
- This example will create multiple copies of the Keras experiment-template, with different hyperparameter
combinations

Experiment Pipeline examples:

- [First step experiment](https://github.com/allegroai/clearml/blob/master/examples/automation/task_piping_example.py)
- This example will "process data", and once done, will launch a copy of the 'second step' experiment-template
- [Second step experiment](https://github.com/allegroai/clearml/blob/master/examples/automation/toy_base_task.py)
- In order to create an experiment-template in the system, this code must be executed once manually
