Kafka Slurm Agent

The Kafka Slurm Agent is a distributed computing and stream processing engine that can be used to run python code across multiple SLURM managed HPC clusters or individual workstations. It uses Kafka (3.x) to asynchronously communicate with agents installed on clusters and workstations. It contains a monitoring tool with a Web JSON API and a job submitter. It is a pure Python implementation using faust stream processing

Installation.

Use the standard pip tool to install. The recommended way is to use a Python virtual environment:

python3 -m venv venv

source venv/bin/activate

pip install kafka-slurm-agent

Quick User Guide

Create a new project

In the folder in which you created the venv subfolder run the following command:

kafka-slurm create-project --folder .

This will generate the following files:

kafkaslurm_cfg.py - the configuration file
Startup scripts for worker-agent, cluster-agent and monitor-agent
An example file to run your code (run.py)
The job submitter example (submitter.py)
The class that can be optionally used to override the existing implementation of the worker-agent (my_worker_agent.py)

Configuration

Please adjust the config file. The config file name can be also injected using the KSA_CONFIG_FILE environment variable

Modify the configuration of the connection to Apache Kafka. The default one assumes that kafka is running on localhost and default port (9092) and doesn't use authentication or SSL. In the comments you will find parameters necessary to connect to Kafka configured using SASL and plaintext password. If you use this type of connection please uncomment also the line that starts with: # KAFKA_FAUST_BROKER_CREDENTIALS
Make sure that PREFIX points to the location of your project
Change the names of topics used for your project to avoid any conflict with projects sharing the same kafka instance.
If you want to use a SLURM cluster please change the job CLUSTER_JOB_NAME_SUFFIX = '_KSA' to avoid conflicts with other projects running on your slurm cluster. The jobs managed by cluster-agent will be named "JOBID_SUFFIX" where the JOBID is the identifier that you assign when submitting a job and SUFFIX is handled by this configuration parameter.

For a full list of configuration parameters refer to the documentation.

Creating topics on Kafka with appropriate partitions

Use the built-in command kafka-slurm to create topics. You should set the --new-topic-partitions paramter to at least the number of planned clusters and workstations that will be used simultaneously. For example:

kafka-slurm --new-topic-partitions 4 topics-create

Implement your code

An example of a script that you can implement is generated in run.py

Submitting jobs

Once this is ready, you can test your project locally:

Open a new terminal and start the worker-agent (./start_worker_agent)
Open a new terminal and start the monitor-agent (./start_monitor_agent)
Submit new jobs using the submitter.py

You can monitor the execution by opening http://localhost:6067/mon/stats/ on the host on which you've started the monitor-agent.

Kafka

For development and testing purposes, you can use Kafka in Docker:

docker run -d -p 9092:9092 --name broker apache/kafka:3.9.1

Demo project

You can download and directly run a demonstration project: https://github.com/ilbsm/ksa_demo

Limitations

Due to the underlying libraries (faust-streaming and it's dependency: aiokafka) currently Kafka 4.0 is not supported.
