Get Available Resources

Build a conservative picture of resources available to the current process. Keep host inventory, process affinity, cgroup/container limits, scheduler allocation, and accelerator runtime usability separate.

Safety contract

Follow these rules:

  • Run detection when the user requests it or a specific workload needs resource planning. Do not persist a fingerprint for every scientific task.
  • Use stdout by default. Persist only when the user chooses an explicit generic local filename.
  • Do not run stress tests, benchmarks, large allocations, write probes, device resets, driver installation, or clock/power changes.
  • Do not dump the environment. Read only the named Slurm and accelerator variables implemented by the detector.
  • Do not report hostnames, absolute paths, cgroup paths, job IDs, device UUIDs, PCI addresses, or raw visibility-variable values.
  • Treat a missing observation as unknown. Never convert unknown to unlimited.
  • Never infer that a visible host CPU, memory pool, or GPU is usable inside a scheduler allocation or container.

The bundled detector uses only fixed executable/argument tuples, no shell, short timeouts, bounded stdout/stderr, and partial-failure warnings.

Quick start

Run from this skill directory.

Ephemeral stdout snapshot

python scripts/detect_resources.py

The command emits only JSON to stdout. Redirect it only when ordinary shell permissions are acceptable.

Explicit private file

python scripts/detect_resources.py --output resource-snapshot.json

Explicit output is restricted to one .json filename in the current directory, uses private permissions, rejects symlinks and path traversal, and refuses overwrite unless --force is supplied.

Optional psutil enhancement

The standard-library detector works without installation. For broader cross-platform physical-core, affinity, available-memory, swap, and disk coverage:

uv pip install "psutil==7.2.2"

The import is lazy. Failure to import psutil becomes a warning, not a fatal error.

Skip management-tool probes

python scripts/detect_resources.py --skip-accelerators

Use this when accelerator discovery latency is undesirable. The detector still summarizes the presence and state of allowlisted visibility variables without returning their values.

Required interpretation

CPU

Read these as different facts:

  • cpu.host.logical: system-visible scheduling units.
  • cpu.host.physical: physical topology, or null; never inferred from logical count.
  • cpu.process.affinity_logical: current affinity-set size when supported.
  • cpu.cgroup_v2.cpuset_logical: effective cgroup cpuset size.
  • cpu.cgroup_v2.quota_cores: finite cpu.max capacity, possibly fractional.
  • scheduler.allocation.cpu_per_process: bounded Slurm per-task interpretation when scope is clear.
  • cpu.effective.capacity_cores: minimum positive observed constraint.
  • cpu.effective.worker_ceiling: conservative floor for CPU process workers.

A quota of 1.5 is CPU-time capacity, not 1.5 physical cores. Affinity and cpusets constrain placement; quota constrains bandwidth.

Memory

Keep these separate:

  • host total/available memory;
  • current cgroup usage, hard memory.max, and remaining hierarchical capacity;
  • memory.high, which is a pressure/throttle boundary rather than a hard cap;
  • scheduler memory allocation and its scope; and
  • conservative effective hard limit and available estimate.

On Apple silicon, memory.model is unified_cpu_gpu. Do not add integrated GPU memory to RAM or describe it as separate VRAM.

Accelerators

Each device is a backend candidate:

  • NVIDIA GPU → CUDA candidate;
  • AMD GPU → ROCm candidate;
  • Apple integrated GPU → Metal candidate.

Management-query visibility does not establish:

  1. scheduler/container permission;
  2. device-node access;
  3. driver/runtime compatibility;
  4. framework package compatibility; or
  5. operator/data-type support.

Therefore runtime_usable_devices remains null and each device says runtime_compatibility: not_tested. Visibility/allocation counts are upper bounds, not guarantees.

Disk

capacity_bytes, filesystem free_bytes, user-available blocks, and a non-writing permission check are distinct. Filesystem or project quotas can still be stricter. The absolute working path is always redacted.

Scheduler and container

Slurm variables describe allocation scope, but enforcement depends on site configuration such as task affinity or cgroups. Prefer affinity and cgroup observations as enforcement evidence.

Container markers identify context; cgroup controls identify limits. A container with no finite cgroup value can still see host inventory, and a non-root cgroup is not automatically labeled a container.

See references/resource_semantics.md for the detailed platform rules.

Plan a workload

The planner consumes a validated snapshot and performs no work:

python scripts/plan_workload.py resource-snapshot.json \
  --workload cpu \
  --tasks 100 \
  --memory-per-worker-mib 2048

Optional controls:

  • --workers N: explicit upper bound.
  • --reserve-memory-mib N: memory kept outside the worker budget.
  • --workload cpu|mixed|io: selects a bounded worker heuristic.
  • --accelerator none|any|cuda|rocm|metal: requests a candidate backend decision without claiming usability.
  • --output plan.json: explicit private local output; stdout is default.

For CPU or mixed work, use suggested_workers and threads_per_worker together. Process workers multiplied by BLAS/OpenMP native threads can oversubscribe an allocation.

The I/O plan permits bounded oversubscription (maximum 32) but labels it a heuristic. Benchmark only the real representative workload and stay within scheduler/container limits.

Validate or diff snapshots

Validate:

python scripts/snapshot_tools.py validate resource-snapshot.json

Diff resource state while ignoring observed_at:

python scripts/snapshot_tools.py diff before.json after.json

Use --include-volatile to include the timestamp. Inputs must be regular, non-symlink JSON files no larger than 1 MiB. Diffs are bounded.

The schema and null/zero meanings are documented in references/snapshot_schema.md.

Optional accelerator diagnostic plan

Generate a plan without executing any diagnostic:

python scripts/accelerator_diagnostics.py resource-snapshot.json \
  --backend auto

The result contains fixed, read-only management query argument lists and separate gates for visibility, permission, and runtime compatibility. Run a framework's official availability check only in the exact environment that will execute the workload. Do not install or mutate drivers automatically.

Partial failures and provenance

One failed probe must not erase successful observations. Inspect:

  • completeness;
  • sorted warnings with stable codes;
  • sorted provenance source/status records; and
  • null fields.

Subprocess stderr and raw exception text are not copied into the snapshot because they can contain identifiers or paths.

Platform notes

  • Linux: reads only bounded /proc and cgroup v2 files. Ancestor CPU and memory limits are considered.
  • macOS: uses fixed sysctl keys and a bounded system_profiler SPDisplaysDataType -json query. Apple silicon memory is unified.
  • Windows: optional psutil improves physical-core, affinity, available memory, and swap observations. Processor-group scope can make host and process counts differ.
  • Slurm: reads an allowlist of allocation variables. It never emits job, node, submit-host, GPU-ID, or path values.
  • NVIDIA/AMD: management CLIs are optional. Absence is normal; timeout, truncation, parse failure, and runtime uncertainty remain explicit.

Resource Semantics

Research and behavior cut-off: 2026-07-23. See sources.md for the official documentation used.

Core rule: inventory is not entitlement

Never treat a host-wide count as a promise that the current process can use it. Interpret usable resources as the intersection of independently observed constraints:

  1. host inventory;
  2. process affinity or processor-group scope;
  3. cgroup/container constraints;
  4. scheduler allocation;
  5. accelerator visibility and device permissions; and
  6. application runtime compatibility.

Missing evidence means unknown, not unlimited. Scheduler variables can describe an allocation without proving that affinity or cgroup enforcement is enabled. Conversely, a cgroup or affinity mask can be stricter than the scheduler request.

CPU

Physical and logical CPUs

  • A logical CPU is an operating-system scheduling unit. Simultaneous multithreading can expose multiple logical CPUs on one physical core.
  • A physical-core count describes topology, not the number of independent workers the process may start.
  • os.cpu_count() and psutil.cpu_count(logical=True) are host/system inventory. They can exceed the CPUs usable by the process.
  • os.process_cpu_count() (Python 3.13+) is process-aware. On supported platforms, affinity APIs provide a more explicit process constraint.
  • On Windows systems with multiple processor groups, a system-wide logical count and one process/thread group's usable count can differ.

The detector reports host logical and physical counts separately. It never derives physical cores from a logical count.

Affinity, cpusets, and quotas

  • Process affinity limits the logical CPUs on which a process may execute.
  • Linux cpuset.cpus.effective reports CPUs actually granted after parent constraints. The requested cpuset.cpus can differ.
  • /proc/self/status exposes Cpus_allowed_list, but the detector prefers affinity APIs and cgroup effective cpusets.
  • cgroup v2 cpu.max is $MAX $PERIOD. max means no local bandwidth limit. A finite ratio is CPU-time capacity, possibly fractional; it is not a core topology count.
  • Parent cgroups also constrain children, so the detector takes the most restrictive finite ancestor quota.

For a cpu.max ratio of 1.5, the snapshot reports capacity_cores: 1.5 and a conservative CPU-bound worker ceiling of 1. A workload may choose more threads for latency hiding, but it should expect throttling and must not describe those threads as 1.5 physical cores.

Python worker pools

  • Current Python multiprocessing.Pool and ProcessPoolExecutor defaults use os.process_cpu_count() when available.
  • Python 3.14 no longer uses fork as the default start method on any platform. Code that depends on a particular start method must request it deliberately.
  • Process workers do not make each worker's native-library threads disappear. BLAS/OpenMP threads multiplied by process workers commonly oversubscribe an allocation.
  • Windows ProcessPoolExecutor has a documented maximum of 61 workers.

Use the workload planner's worker and threads-per-worker values as conservative ceilings, then benchmark a real representative workload. Do not run a synthetic stress test merely to discover capacity.

Memory

Host and effective memory

  • psutil.virtual_memory().total and .available describe system-visible memory, not necessarily the process limit.
  • Linux /proc/meminfo MemAvailable is the standard-library fallback for a host-availability estimate.
  • cgroup v2 memory.current is current cgroup usage.
  • memory.high is a throttle/reclaim pressure boundary. Exceeding it does not itself invoke the cgroup OOM killer, and the value can be breached.
  • memory.max is the hard cgroup limit. If usage cannot be reduced at that boundary, the cgroup OOM killer can run.
  • Parent memory limits are hierarchical. Shared ancestor usage can reduce what remains for a child, so effective remaining memory is the minimum finite limit - current observed through the ancestor chain.
  • Slurm memory variables describe requested/allocated memory, but strict enforcement depends on site configuration.

The detector keeps host total/available values, cgroup values, scheduler values, and the conservative effective values distinct. A point-in-time "available" value can change immediately and is not a reservation.

macOS unified memory

On Apple silicon, CPU and integrated GPU share unified memory. Do not add a fictional GPU VRAM amount to system RAM. The snapshot marks the memory model as unified_cpu_gpu and leaves dedicated GPU memory null. Metal framework support and model/operator support still require application-specific checks.

Accelerators

Accelerator usability has separate layers:

  1. Hardware or management visibility — a management query returns a device.
  2. Allocation visibility — scheduler and named visibility variables permit a device or a subset.
  3. Device permission — the process/container can open the required device interfaces.
  4. Driver/runtime compatibility — driver, CUDA/ROCm/Metal runtime, and framework versions are compatible.
  5. Workload compatibility — the requested operation and data type are implemented on that backend.

nvidia-smi success confirms NVIDIA management visibility only. It does not prove that CUDA libraries exist or are compatible. NVIDIA documents driver and runtime compatibility as a separate requirement.

AMD SMI or ROCm SMI success likewise does not prove HIP/ROCm runtime usability. New deployments should prefer amd-smi; rocm-smi is retained as a read-only fallback. On Linux, AMD recommends ROCR_VISIBLE_DEVICES; on Windows it recommends HIP_VISIBLE_DEVICES.

An Apple integrated GPU is a Metal candidate, not a CUDA GPU. AMD GPUs are ROCm candidates, not CUDA GPUs. Neural engines, TPUs, FPGAs, and other accelerators must also remain distinct from CUDA devices if another inventory source adds them.

The detector reads only these accelerator variable names and redacts their values:

  • NVIDIA_VISIBLE_DEVICES
  • CUDA_VISIBLE_DEVICES
  • ROCR_VISIBLE_DEVICES
  • HIP_VISIBLE_DEVICES

Counts derived from those values are only upper bounds. Environment variables are not a security boundary and can be reset by an application; device namespace/cgroup controls are stronger isolation.

Slurm and other schedulers

The detector allowlists named Slurm variables and never dumps the environment. It records field names, parsed bounded counts, and memory quantities, but not job IDs, GPU UUIDs, node names, submit hosts, or paths.

Important scopes:

  • SLURM_CPUS_PER_TASK: requested CPUs per task; suitable as a per-process upper bound for one task process.
  • SLURM_CPUS_ON_NODE: CPUs allocated to the current batch step on the node; it can be shared among tasks.
  • SLURM_JOB_CPUS_PER_NODE: a per-node allocation list, not a process count.
  • SLURM_MEM_PER_CPU: memory per allocated CPU. It becomes a per-task bound only when CPUs per task is known.
  • SLURM_MEM_PER_NODE: shared per-node memory upper bound.
  • SLURM_GPUS_PER_TASK: requested GPUs per task.
  • SLURM_GPUS_ON_NODE: GPUs allocated to the batch step on the node.

Slurm CPU confinement requires site configuration such as task affinity or task/cgroup with core constraints. Memory requests are not strictly enforced unless the site enables an enforcement mechanism. Use affinity and cgroup observations as enforcement evidence; do not trust visible node inventory.

For other schedulers, use their documented allocation API or variables and the same rule: allocation metadata and kernel enforcement are different facts. Do not guess from generic environment names.

Containers and OCI

Docker containers have no CPU or memory limit by default. When configured, Docker maps CPU and memory flags to cgroup controls. OCI runtime configuration also defines CPU, memory, and device constraints.

Inside a container:

  • host inventory may remain visible;
  • a CPU quota can be smaller than the visible CPU set;
  • a cpuset can be smaller than the quota's apparent capacity;
  • cgroup memory can be smaller than host RAM;
  • GPU management tools can see a different set from the application runtime; and
  • mounted-volume capacity can differ from writable quota.

Always report observed cgroup controls and uncertainty. A container marker without a finite cgroup value does not imply a finite limit.

Disk

Capacity, free blocks, user-writable blocks, path permission, filesystem quota, and actual ability to complete a write are different:

  • capacity is the filesystem's total size;
  • free blocks can include blocks reserved from an unprivileged user;
  • POSIX f_bavail estimates blocks available to the current user;
  • os.access(..., os.W_OK) is a non-writing permission check, not proof that a future write will succeed;
  • project/user quotas and remote storage policies can be stricter than block counts.

The detector does not create a probe file. It redacts the absolute working path and labels the scope as the working filesystem.

references/snapshot_schema.md (verbatim)

Snapshot Schema 1.1

The detector emits one JSON object with sorted keys. Values vary by observation, but field names and meanings are stable for schema 1.1.

Top-level contract

  • schema_version: "1.1".
  • snapshot_kind: "effective_resource_snapshot".
  • observed_at: UTC observation time.
  • completeness: complete, complete_with_informational_notes, or partial.
  • platform: OS family, architecture, and Python version. Hostname is omitted.
  • privacy: explicit redaction flags.
  • cpu, memory, disk, accelerators: resource observations.
  • cgroup_v2, container, scheduler: execution-context observations.
  • warnings: bounded sorted warning records.
  • provenance: bounded sorted source/status records.

Null means unavailable, not zero and not unlimited. Zero is used only when a source explicitly establishes zero (for example, a named accelerator visibility variable that hides all devices).

CPU

cpu.host:

  • logical: system-visible logical CPUs.
  • physical: system-visible physical cores, or null. This value is not converted into an effective process count.

cpu.process:

  • affinity_logical: size of the current affinity set when supported.
  • python_available_logical: os.process_cpu_count() when supported.

cpu.cgroup_v2:

  • cpuset_logical: count from cpuset.cpus.effective.
  • quota_cores: most restrictive finite ancestor cpu.max ratio. This may be fractional.

cpu.effective:

  • capacity_cores: minimum positive host/process/cgroup/scheduler capacity.
  • worker_ceiling: conservative bounded floor for CPU process workers.
  • limiting_sources: sources tied at that minimum.

The effective value is intentionally not called a physical-core count.

Memory

memory.host preserves system-visible total_bytes and available_bytes.

memory.cgroup_v2 preserves current-cgroup usage and hierarchical effective limits:

  • current_bytes
  • available_bytes
  • high_bytes
  • max_bytes

memory.effective:

  • hard_limit_bytes: minimum of finite host total, cgroup hard limit, and interpretable scheduler allocation.
  • available_bytes: minimum of host available, hierarchical cgroup remaining, and scheduler upper bound.
  • pressure_threshold_bytes: cgroup memory.high; it is not relabeled as a hard limit.
  • hard_limit_sources and available_limiting_sources: tied minimum sources.

memory.model is unified_cpu_gpu on Apple silicon and system_ram otherwise. Unified GPU memory is not added again as dedicated VRAM.

Disk

  • capacity_bytes: total working-filesystem capacity.
  • free_bytes: filesystem free blocks.
  • user_available_bytes: user-available blocks where the OS exposes them.
  • writable: result of a non-writing access check.
  • writability_check: makes clear that no write probe occurred.
  • scope: working_filesystem_path_redacted.

None of these values proves that a filesystem or project quota permits a write of the same size.

Accelerators

accelerators.devices contains management-visible or explicitly platform-inferred candidates:

  • vendor: nvidia, amd, or apple.
  • device_class: keeps integrated and discrete GPU concepts distinct.
  • backend_candidate: cuda, rocm, or metal.
  • management_query: visibility evidence.
  • device_permission: not_tested; a query does not prove device-node access.
  • runtime_compatibility: not_tested in detector output.
  • memory.model: dedicated/HBM, unified, or unknown.
  • local_index: local query index; stable UUIDs and PCI addresses are omitted.

candidate_counts is a query count, not a usable-device count. candidate_upper_bounds conservatively intersects query count with parsed visibility/allocation counts when available. runtime_usable_devices remains null because no framework runtime is loaded.

visibility_environment includes only four allowlisted variable names. Raw values are never emitted.

Scheduler and cgroup

scheduler.fields_read lists allowlisted Slurm names that were present. scheduler.allocation contains parsed bounded values and scopes. scheduler.enforcement remains unknown; variables alone do not prove confinement.

cgroup_v2.scope says only root, non_root, unknown, or not_applicable. The cgroup path is not emitted.

container.detected requires a known marker. A cgroup_limit can appear as evidence without asserting that the process is in a container.

Warnings and provenance

Warnings use:

{
  "code": "STABLE_MACHINE_CODE",
  "component": "cpu",
  "message": "Human-readable, sanitized explanation.",
  "severity": "info"
}

Probe exception text, stderr, paths, hostnames, device UUIDs, and broad environment content are excluded.

Provenance uses:

{
  "component": "cpu.process.affinity_logical",
  "source": "os.sched_getaffinity",
  "status": "ok"
}

Possible status values include ok, unavailable, absent, skipped, not_found, timeout, truncated, error, and parse_error.

Validation and diff

Validate:

python scripts/snapshot_tools.py validate resource-snapshot.json

Diff while ignoring observed_at:

python scripts/snapshot_tools.py diff before.json after.json

Use --include-volatile only when timestamp changes matter. Diff output is bounded to 512 changes.

All helper inputs are regular, non-symlink JSON files no larger than 1 MiB. Output defaults to stdout. Explicit file output is restricted to a .json filename in the current directory, refuses overwrite unless --force is used, and is opened with private permissions.
