Computational environment

The full software and hardware context in which an analysis runs, including operating system, language runtime, library versions, configuration, environment variables, and hardware-specific dependencies (e.g., GPU drivers).

Ask about Computational environment

Answers are drawn from this dictionary entry and the rest of the CASRAI corpus, with a link to every source.

Answers are AI-generated from CASRAI’s own published pages and can be wrong, so check the linked sources before relying on one; your question is logged without personal data — never sold, never used to train a third-party model — to show us what CASRAI is missing, so please do not type personal or confidential details. How we use this

Examples

Worked examples

Is an instance
A renv.lock file pinning every R package version used by an analysis.
Is an instance
A Dockerfile producing a reproducible Ubuntu 22.04 image with Python 3.11 and pinned dependencies.

Counter-examples

Looks similar, but isn't

Not an instance
A 'requirements.txt' with unpinned versions (>= or ranges).
Not an instance
A README listing language versions without pinning libraries.

Editorial commentary

Capturing the computational environment is a prerequisite for computational reproducibility because the same code may produce different results under different library versions, BLAS implementations, or floating-point modes. Approaches include lock files (renv, Poetry, conda-lock), container images, and full virtual machines.
