Struct DeviceResourceProfile 

pub struct DeviceResourceProfile {
    pub device_ordinal: usize,
    pub device_capabilities: DeviceCapabilities,
    pub managed_capacity_bytes: u64,
    pub default_query_limit_bytes: u64,
    pub max_active_attempts: usize,
    pub root_lane_count: usize,
    pub root_stream_count: usize,
    pub source_work_per_attempt: usize,
    pub stream_pool_size: usize,
    pub worker_job_capacity: usize,
    pub cache_cap_bytes: u64,
    /* private fields */
}

Frozen capacity and execution-slot bounds for one CUDA device.

cache_cap_bytes (K) reserves a bounded per-device cache share taken from the managed capacity (M). Query grants and frozen residents share only the remaining query share (Q = M - K); query admission never promises the same bytes that back the cache share.

Fields

device_ordinal: usize

CUDA device whose ledger owns this resource profile.

device_capabilities: DeviceCapabilities

Capability metadata frozen with this device’s resource envelope.

managed_capacity_bytes: u64

M: the bytes the ledger may promise to grants, residents, and cache.

default_query_limit_bytes: u64

Default immutable grant in bytes, before any resident-capacity adjustment at admission.

max_active_attempts: usize

A_d. Also the number of lifecycle job permits, root streams, and attempt lanes.

root_lane_count: usize

Equals max_active_attempts; one lane per admitted attempt.

root_stream_count: usize

Equals max_active_attempts; one root stream per admitted attempt.

source_work_per_attempt: usize

S_d, normalized to at least 1.

stream_pool_size: usize

At least A_d + A_d * S_d, checked by resolve.

worker_job_capacity: usize

At least A_d + A_d * S_d, checked by resolve.

cache_cap_bytes: u64

Cache share reserved from managed capacity in bytes.

Implementations

impl DeviceResourceProfile

pub fn query_share_bytes(&self) -> u64

Query share (Q = M - K) promisable to grants plus frozen residents.

Cache charges (C <= K) never participate in this share, so query admission and cache eviction cannot promise the same bytes.
