Python API

import scitex_resource as r

# Hub-friendly metrics (cross-platform via psutil)
metrics = r.get_metrics()

# Canonical host identity
name = r.get_host_name()
cfg = r.get_host_config()        # {"canonical_name", "aliases", "role", "hpc": {...}}

# Rich snapshot
specs = r.get_specs()

# CPU/RAM/GPU/VRAM samples + continuous CSV logging
usage = r.get_processor_usages()
r.log_processor_usages(limit_min=30, interval_s=1)
# default: ~/.scitex/resource/runtime/processor_usages.csv

# Cap process RAM
r.limit_ram(0.5)

CLI

# Host identity
$ scitex-resource hosts show
$ scitex-resource hosts config show --json

# System specs and live metrics
$ scitex-resource specs
$ scitex-resource metrics show --json

# Processor usage snapshot + continuous CSV log
$ scitex-resource processor-usages show --json
$ scitex-resource processor-usages log --interval 5 --max-rows 12

# Cap process RAM
$ scitex-resource ram-limit 0.8

Quick Start

import scitex_resource as r

print(r.get_host_name())           # canonical host identity
metrics = r.get_metrics()          # cpu / mem / disk / gpu / load
specs = r.get_specs()              # rich human-readable snapshot

Host identity config — ~/.scitex/resource/config.yaml

host:
  canonical_name: mba                 # what every scitex-* package uses to refer to this host
  aliases:                            # optional; cross-package discovery / drift detection
    - Yusukes-MacBook-Air
    - Yusukes-MacBook-Air.local
  role: head                          # generic role tag (head, worker, hpc-login, ...)
  hpc:                                # optional; HPC-only
    cluster: spartan
    login_only: true
    partitions: [physical, sapphire]

Resolution cascade (highest precedence first):

1. $SCITEX_RESOURCE_HOST
2. <project>/.scitex/resource/config.yaml host.canonical_name
3. ~/.scitex/resource/config.yaml host.canonical_name
4. socket.gethostname().split(".", 1)[0]

(Deprecated $SCITEX_RESOURCE_MACHINE and machine: config block are still honoured as fallbacks with a one-time DeprecationWarning.)

Status

Standalone fork of scitex.resource. Deps: pandas, psutil, PyYAML, click.

Decoupling notes:

• scitex.str.readable_bytes / scitex.gen.fmt_size / scitex.str.printc → vendored as small helpers in _compat.py.
• scitex.io._load.load / scitex.io._save.save → use pandas.read_csv / to_csv directly for the CSV log files.
• scitex.sh.sh → prefer scitex_sh if installed, fall back to plain subprocess.run (list-only).

The umbrella package's scitex.resource import path is preserved via a sys.modules-alias bridge.

Part of SciTeX

scitex-resource is part of SciTeX. Install via the umbrella with pip install scitex[resource] to use as scitex.resource (Python) or scitex resource ... (CLI).
