dftracer-references

DFTracer documentation links, artifact log locations, step numbering, and how to read session logs

software-hdf5

HDF5 optimization strategies (L2 software tuning), version compatibility, ALWAYS building HDF5 from source (never Cray/system module), Cray HDF5 pitfalls, and dftracer HDF5 tracing setup. Load this skill for any HDF5 or parallel I/O work.

dftracer-annotate-project

Project-level annotation router that scopes files and dispatches by language.

dftracer-build-app

Build the original application session with the smallest useful context and record build lessons early.

dftracer-project-router

Project-level router for dftracer stage subagents, model selection, and tool delegation.

dftracer-smoke-test

Smoke test rules for dftracer — single-process only, environment variables, DFTRACER_INIT conflict warning, and trace file paths

dftracer-system-detect

Detect the runtime system, modules, allocation shape, and environment assumptions for dftracer sessions.

software-pegasus

Install and run Pegasus workflows (e.g. montage-workflow-v3) on HPC systems without a site-wide HTCondor pool, using Pegasus MPI Cluster (PMC) under a Flux/Slurm allocation instead of Condor+DAGMan. Covers userspace install of Condor (for pegasus-plan tooling…

software-posix

POSIX I/O optimization strategies: application-level buffering (L1), readahead and library hints (L2), OS/filesystem tuning (L3), and dftracer DATA_DIR configuration for capturing POSIX events. Load this skill for any POSIX I/O bottleneck work.

system-tuolumne-rabbit

Rabbit near-node-flash storage accelerators on Tuolumne — DW directives via Flux -S "#DW ...", picking SHM vs XFS vs GFS2 vs Lustre by data-sharing scope, and how to use them as an L3 filesystem optimization to accelerate data access.

dftracer-annotate-cpp

C++ annotation rules for dftracer — RAII guard, REGION macros for main, UPDATE usage, and quick checklist

dftracer-build-run

Annotation-build-run iteration loop for dftracer — manual mode for when the pipeline exhausts retries or you are working interactively

dftracer-pitfalls

Annotation pitfalls — real mistakes that caused build failures or missing trace data, with root causes and exact fixes

dftracer-planning

Planning, progress reporting, and live progress rules for dftracer sessions — how to structure multi-step work and report expensive steps
