nform

nFORM is a parallel computer algebra system that extends the FORM language to support large-scale symbolic computations on distributed computing resources. It is part of the FORM family, designed for symbolic manipulation in high-energy physics and related fields. The 'n' in nFORM stands for new, reflecting its focus on parallel processing to handle very large expressions beyond a single processor's capacity.

Developed to meet the computational demands of modern particle physics, nFORM preserves much of FORM’s programming model and syntax while adding distributed processing capabilities. Typical deployments run on clusters or HPC systems using MPI, distributing terms or groups of terms across processors and aggregating results.

Key capabilities include a domain-specific language for symbolic manipulation, modular programming with include files, and interoperability with other FORM-based tools. It is designed to manage extremely large expression trees efficiently by streaming data between nodes and minimizing communication overhead.

nFORM is used primarily in academic research, especially in high-energy physics, to simplify large algebraic expressions, perform substitutions, and prepare results for numerical evaluation. Documentation and community resources cover installation, syntax, and parallelization strategies.
