Struct MegakernelDeviceCapabilities 

pub struct MegakernelDeviceCapabilities {
    pub supports_device_wide_barrier: bool,
}

Device capabilities that constrain which wave topologies are launchable.

Fields

supports_device_wide_barrier: bool

Whether every resident block can synchronize inside one launch.

Implementations

impl MegakernelDeviceCapabilities

pub const FUSION_CAPABLE: Self

Device that can host a fused wave.

pub const FUSION_INCAPABLE: Self

Device that must keep every wave in its own launch.

pub fn admissible_fusion_pressure(self, fusion_pressure: f64) -> f64

Fusion pressure this device can act on.

Without a device-wide barrier the fused plan is unlaunchable, so the measured pressure toward it is zero however high the caller observed it.
