# ncuhep

A collection of high-energy and astroparticle physics utilities focused on **muography** and **dimension-aware units**. The library bundles a full muon tracking pipeline, a lightweight units system, and small helpers such as an SSH-based job scheduler for remote clusters.

## Features
- **Muography (`ncuhep.muography`)**
  - Parse raw DAQ `_Mu.txt` files into timestamped hits with configurable counter unwrapping and glitch suppression.
  - Identify coincident events per detector layer and reconstruct straight-line tracks with χ² scoring.
  - Generate Monte Carlo response bases and geometric factors for flux reconstruction, plus helpers for flux post-processing and visualization.
- **Units (`ncuhep.units`)**
  - SI-centric unit classes with attribute-based getters/setters (e.g., `Length`, `Time`, `Flux`, `Density`).
  - Automatic dimensional arithmetic with registry-backed derived quantities, plus helpers for custom unit definitions.
- **Job scheduling (`ncuhep.job_scheduler`)**
  - A minimal SSH-based dispatcher that probes remote CPU load and assigns jobs across hosts, with optional submission time windows.

## Installation
Requires **Python 3.11+**.

From PyPI:
```bash
pip install ncuhep
```

From source (editable):
```bash
git clone <this-repo>
cd ncuhep
pip install -e .
```

GPU acceleration for Monte Carlo rendering uses Numba/CUDA when available but is optional.

## Quickstart
### Muography pipeline
Below is a minimal sketch of how the parser → identifier → tracker pipeline fits together. Configure your detector geometry, DAQ file format, and analysis cuts before running the chain.

```python
from ncuhep.muography import parser, identifier, tracker
from ncuhep.muography.classes import PlaneDetector, MuTxtFormat, AnalysisConfig

# Load detector geometry (JSON layout exported via PlaneDetector._export())
det = PlaneDetector()
det._import("detector_config.json")

# Describe your raw _Mu.txt format
fmt = MuTxtFormat()
fmt._import("mu_txt_format.json")

# Analysis cuts (time clustering, hit thresholds, etc.)
cfg = AnalysisConfig()
cfg._import("analysis_config.json")

# Parse one run, then build events and tracks
hits, live_time = parser("/data/runs", "run001_Mu.txt", fmt, det, cfg, return_hits=True)
events = identifier(hits, det)
tracks = tracker(events, det)

print(f"Reconstructed {len(tracks)} tracks with {live_time/3600:.2f} hours of live time")
```

### Units and dimensional arithmetic
The units module exposes base quantities (length, time, counts, angle, etc.) and common derived types. Values are stored internally in SI and converted via attribute access.

```python
from ncuhep.units import Length, Time, Flux

L = Length()
L.cm = 50   # store as 0.50 m internally

T = Time()
T.s = 120

Φ = Flux()
Φ.counts_m2_s_sr = 200

area = L * L          # -> Area
live_time = T.h       # numeric hours view
fluence = Φ * T       # dimensional arithmetic preserved
print(area.unit)      # "m^2"
```

Custom units can be registered at runtime using `make_custom_unit` or `make_custom_unit_from_signature` for niche dimensions.

### Lightweight SSH job scheduling
`ncuhep.job_scheduler.smart_scheduler.SSHJobScheduler` provides a small “poor man’s Slurm” for dispatching many similar jobs across SSH-accessible hosts.

```python
from ncuhep.job_scheduler.smart_scheduler import SSHJobScheduler
import numpy as np

scheduler = SSHJobScheduler(
    hosts=["chip03", "chip04"],
    remote_workdir="/data/workdir",
    executable="/path/to/python",      # or a compiled binary
    script_path="/data/workdir/run.py", # used when executable is Python
    cpu_threshold=50.0,
    max_jobs_per_host=2,
)

# Dispatch a grid of arguments; each column is one positional argument
results = scheduler.dispatch_many_from_columns(
    np.arange(0, 5),   # arg0
    np.linspace(0, 1, 5),  # arg1
)
print(results)
```

## Project structure
- `ncuhep/muography/` – core muography pipeline, Monte Carlo rendering, scatter modeling, profiling tools, and utilities (tracking, coordinates, flux processing).
- `ncuhep/units/` – unit definitions and dimensional arithmetic helpers.
- `ncuhep/job_scheduler/` – SSH job dispatcher with CPU probing and submission time windows.

## Development
- Install dependencies with `pip install -e .` in a Python 3.11+ environment.
- Formatting and linting are not enforced by tooling in-repo; please keep style consistent with existing NumPy/scipy-oriented code.
- Tests are not bundled; exercising the parser/identifier/tracker pipeline on a small `_Mu.txt` sample is recommended before larger runs.
