Module: tide.storage

Snapshot storage helpers for backward propagation.

Functions

• storage_mode_to_int

Classes

• TemporaryStorage

Storage Modes

• device: snapshots stay on compute device, fastest and most memory-heavy
• cpu: host-backed storage, lower device memory use
• disk: file-backed storage, smallest memory footprint and highest latency
• none: disable snapshot storage

The user-facing APIs also accept auto, which chooses mode based on configured byte limits.

storage_mode_to_int

Maps mode strings to backend integer constants used by native kernels.

Compression

• storage_compression supports none and bf16 on default compute path
• bf16 storage is valid for float32 workflows

TemporaryStorage

• Creates an isolated temporary directory under the specified base path
• Generates one file path per logical shot buffer
• Cleans up directory tree on close or object destruction
