Point-in-time device memory allocation-failure report.

Fields

device_ordinal: usize

CUDA ordinal monitored by the installed allocation-failure callback.

callback_installed: bool

Whether the native memory manager updates this report’s tracker.

callback_install_unavailable: bool

Whether callback installation was unavailable; excludes callback_installed.

allocation_failure_count: u64

Allocation failures observed over the memory-manager installation lifetime.

total_failed_allocation_bytes: u64

Sum of failed allocation request sizes in bytes.

largest_failed_allocation_bytes: u64

Largest failed allocation request size in bytes; zero before any failure.

trim_retry_count: u64

Always zero because this memory-manager callback declines allocator retries.

pool_usage_observation_count: u64

Failure callbacks carrying a CUDA async-pool usage sample.

last_failed_allocation_bytes: u64

Most recent failed request size in bytes; zero before any failure.

last_pool_reserved_current_bytes: u64

Pool-reserved bytes from the last callback carrying a pool sample. Zero before the first sample; consult pool_usage_observation_count.

last_pool_used_current_bytes: u64

Pool-used bytes from the last callback carrying a pool sample. Zero before the first sample; consult pool_usage_observation_count.
