Elixir Q & A


How to use Elixir for scientific computing?

Elixir, with its primary focus on concurrency, fault tolerance, and real-time systems, may not be the first choice for scientific computing when compared to languages like Python or Julia, which have extensive libraries and ecosystems dedicated to this domain. However, it can still be used for certain scientific computing tasks, and its unique features can provide advantages in specific scenarios.


Here’s how Elixir can be used in scientific computing:


  1. Parallelism: Elixir’s concurrency model based on lightweight processes, known as actors, allows for easy parallelization of tasks. This can be beneficial for tasks that can be broken down into smaller, independent units of work, such as simulations or data processing. Elixir’s concurrency can make efficient use of multi-core processors.


  1. Distributed Computing: Elixir’s distributed capabilities enable the creation of clusters of nodes, each running Elixir applications. This can be useful for distributed computing tasks, such as running simulations on multiple machines or processing large datasets in parallel.


  1. Integration with External Libraries: While Elixir doesn’t have as extensive a library ecosystem for scientific computing as some other languages, it can interoperate with libraries written in languages like C or Python. You can create Elixir NIFs (Native Implemented Functions) to leverage existing libraries or call Python code using the `:python` Erlang module.


  1. Data Streaming: Elixir’s ability to handle real-time data streaming can be useful in scientific experiments that involve continuous data acquisition and processing.


  1. Custom Solutions: Elixir is a versatile language, and you can build custom solutions tailored to specific scientific computing needs. This can be especially beneficial when you need a highly specialized tool for a particular research project.


However, it’s essential to consider the specific requirements of your scientific computing tasks. Elixir may not be the best choice for computationally intensive tasks that require extensive numerical libraries or advanced visualization capabilities, which languages like Python or Julia excel at. Researchers in fields such as data science, machine learning, or bioinformatics might find Elixir less suited for their primary tasks due to the availability of more specialized tools. Nonetheless, Elixir’s strengths in concurrency and distributed computing can complement scientific computing workflows in certain contexts, making it a valuable addition to a researcher’s toolkit for specific tasks within the broader domain of scientific computing.
