Adding New Capability in Existing Scientific Application with LLM Assistance
With the emergence and rapid evolution of large language models (LLM), automating coding tasks has become an important research topic. Many efforts are underway and literature abounds about the efficacy of models and their ability to generate code. A less explored aspect of code generation is for new algorithms, where the training data-set would not have included any previous example of similar code. In this paper we propose a new methodology for writing code from scratch for a new algorithm using LLM assistance, and describe enhancement of a previously developed code-translation tool, Code-Scribe, for new code generation.
Executive Impact Summary
This paper presents a novel methodology for using Large Language Models (LLMs) to generate code for entirely new algorithms, a challenging task where traditional LLM approaches often fail due to lack of prior training data. By iteratively refining specifications in natural language before code generation, and leveraging an enhanced tool called CodeScribe, the authors demonstrate a significant reduction in model hallucination and improved code quality for complex scientific applications like particle-mesh interactions in Flash-X. The approach emphasizes TDD, modular design, and the benefits of persistent chat context for better documentation and error handling.

This section explores the core challenge of leveraging LLMs for code generation, particularly for novel algorithms without existing training data. It highlights how traditional direct code generation often leads to 'hallucinations' due to imprecise natural language prompts.
The paper introduces a unique methodology centered on iterative specification refinement. Instead of generating code immediately, LLMs are first prompted to articulate their understanding of the problem. This process, facilitated by the enhanced CodeScribe tool using TOML files, allows for precise correction of specifications in natural language, significantly reducing errors before any code is written.
The methodology is applied to develop a new parallel algorithm for handling particle-mesh interactions in Flash-X, a complex multiphysics software system. This application demonstrates the practical utility of the approach in a scientific computing context, leading to robust code for tasks like virtual particle generation and optimized density deposition.

Case Study: Particle-Mesh Interaction in Flash-X
The methodology was successfully applied to develop a new parallel algorithm for handling particle-mesh interactions within Flash-X, a complex multiphysics software system. This critical task involved generating virtual particles and optimizing density deposition, a scenario where no prior code examples existed for LLM training.
The Challenge:
Generating robust and correct code for a novel particle-in-cell algorithm, specifically handling virtual particle creation, migration, and deposition with complex boundary conditions in Flash-X.
The Solution:
Utilizing the iterative specification refinement through CodeScribe, breaking down complex logic into manageable, verifiable tasks. The LLM assisted in developing logic for mirroring particles and integrating with existing AMR framework.
The Outcome:
Successful implementation of a new algorithm that eliminated the costly reverse ghost-cell fill step, resulting in cleaner, more maintainable, and correctly functioning code for scientific simulations.
