From f28295759ba2205903a0715e47cf8d565bdafce8 Mon Sep 17 00:00:00 2001 From: RoryBarnes Date: Mon, 29 Dec 2025 17:25:58 -0800 Subject: [PATCH] Deprecate Hyak PBS/Torque scheduler integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove obsolete PBS/Torque job submission functionality that was specific to UW's legacy Hyak cluster (migrated to Slurm in 2020). Changes: - Delete vspace/hyak.py and vspace/vspace_hyak.py (399 lines removed) - Remove vspace_hyak import from vspace/vspace.py - Remove dead code block (if False:) containing hyak calls (34 lines) - Add TESTING.md documenting subprocess coverage methodology - Update CLAUDE.md Phase 5 to mark deprecation complete - Add deprecation notice to README.md Rationale: 1. Multiplanet provides superior parallel execution without scheduler deps 2. PBS/Torque is legacy; modern HPC uses Slurm 3. Code was already disabled (wrapped in "if False:") 4. Hardcoded for single user (paths: /gscratch/stf/dflemin3/) Users needing HPC integration should use multiplanet in interactive sessions or develop Slurm job array workflows. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- README.md | 8 + TESTING.md | 133 ++++++++++++++++ claude.md | 61 ++----- vspace/hyak.py | 34 ---- vspace/vspace.py | 36 ----- vspace/vspace_hyak.py | 363 ------------------------------------------ 6 files changed, 157 insertions(+), 478 deletions(-) create mode 100644 TESTING.md delete mode 100644 vspace/hyak.py delete mode 100644 vspace/vspace_hyak.py diff --git a/README.md b/README.md index 04326e3..3c73178 100644 --- a/README.md +++ b/README.md @@ -28,3 +28,11 @@ With `VSPACE` you can quickly and easily build input files with specific parameters with different distributions, such as grids, normal distribution, sines and cosines, and even arbitrary distributions.
