getBackendDevice

Resolve the active torch backend device

Description

Resolves (once per session, then cached – see resetGPUCache) the torch device to use for accelerated operations: “cuda” if a CUDA GPU is available, else “mps” on Apple Silicon, else “cpu”. Exposed for downstream packages (e.g. spiDE) that push their own tensors onto the same device SpaNorm is using.

Usage

getBackendDevice()

Value

a character, one of “cuda”, “mps” or “cpu”.

Examples

library("SpaNorm")

getBackendDevice()

[1] "cpu"
