Type Alias DefaultDevice 

pub type DefaultDevice = WgpuDevice;

Aliased Type

pub enum DefaultDevice {
    DiscreteGpu(usize),
    IntegratedGpu(usize),
    VirtualGpu(usize),
    Cpu,
    DefaultDevice,
    BestAvailable,
    Existing(u32),
}

Variants

DiscreteGpu(usize)

Discrete GPU with the given index. The index is the index of the discrete GPU in the list of all discrete GPUs found on the system.

IntegratedGpu(usize)

Integrated GPU with the given index. The index is the index of the integrated GPU in the list of all integrated GPUs found on the system.

VirtualGpu(usize)

Virtual GPU with the given index. The index is the index of the virtual GPU in the list of all virtual GPUs found on the system.

Cpu

CPU.

DefaultDevice

The best available device found with the current graphics API.

This will prioritize GPUs wgpu recognizes as “high power”. Additionally, you can override this using the CUBECL_WGPU_DEFAULT_DEVICE environment variable. This variable is spelled as if i was a WgpuDevice, so for example CUBECL_WGPU_DEFAULT_DEVICE=IntegratedGpu(1) or CUBECL_WGPU_DEFAULT_DEVICE=Cpu

BestAvailable

👎Deprecated

Deprecated, use DefaultDevice.

Existing(u32)

Use an externally created, existing, wgpu setup. This is helpful when using CubeCL in conjunction with some existing wgpu setup (eg. egui or bevy), as resources can be transferred in & out of CubeCL.

Notes

This can be initialized with init_device.
