Expand description

Helper to setup multi-GPU training

Fields§

§contexts: Vec<Arc<GpuContext>>

GPU contexts for each device

§sync_managers: Vec<MultiGpuSync<f32>>

Synchronization managers

Implementations§

Source §

impl MultiGpuSetup

Source

pub fn new( num_gpus: usize, max_param_size: usize, ) -> Result<Self, GpuOptimError>

Initialize multi-GPU setup.

Every logical rank shares the same physical device: scirs2-core 0.6.x has no API to enumerate or address more than one, so there is nothing else this constructor could honestly open. Opens the context via crate::optimizers::SUPPORTED_BACKENDS (the backends this crate actually ships kernels for), never the removed Cuda backend that always errors.
