Module system 

Cross-platform system detection (CPU, RAM, OS, Docker, GPU).

Structs

GpuInfo

One GPU’s identity, capability and VRAM.

Enums

GpuVendor

Which GPU stack a device belongs to.

Functions

arch_dir_name

Convert a ;-separated arch list into a variant directory name. Shared by the libtorch and NCCL source builders so their variant paths cannot drift.

cpu_model

cpu_threads

detect_gpus

Enumerate every installed GPU, ignoring visibility masks. Shorthand for survey when the caller does not need the findings.

docker_version

escape_json

Escape a string for embedding in a JSON string literal. Complete per RFC 8259: backslash, quote, and every control char below 0x20. The hand-rolled predecessors missed \t / \r — one control character in a GPU name or mount path produced invalid JSON, which broke cluster probe fan-in.

has_cargo

Check whether cargo is available on the host.

has_command

Check whether a command exists on PATH.

is_inside_docker

nvidia_driver_version

NVIDIA driver version string, or None when nvidia-smi is absent or errors.

os_version

platform_tag

Platform string for download URLs (e.g. “linux-x86_64”, “macos-arm64”).
