…meta-pytorch#3143) Summary: X-link: meta-pytorch#3143 ### Overview This diff adds support for tracking optimizer states in the Model Delta Tracker system. It introduces a new tracking mode called `MOMENTUM_LAST` that enables tracking of momentum values from optimizers to support approximate top-k delta-row selection. ### Key Changes #### 1. Optimizer State Tracking Support * To support tracking of optimizer states I have added `optim_state_tracker_fn` attribute to `GroupedEmbeddingsLookup` and `GroupedPooledEmbeddingsLookup` classes responsible for traversing over the BatchedFused modules. * Implemented `register_optim_state_tracker_fn()` method in both classes to register the trackable callable * Tracking calls are invoked after each lookup operation. #### 2. Model Delta Tracker Changes * Added `record_momentum()` method to track momentum values from optimizer states and its support in record_lookup function. * Added validation and optim tracker function logic to support the new `MOMENTUM_LAST` mode #### 3. New Tracking Mode * Added `TrackingMode.MOMENTUM_LAST` to [`**types.py**`](command:code-compose.open?%5B%22%2Ffbcode%2Ftorchrec%2Fdistributed%2Fmodel_tracker%2Ftypes.py%22%2Cnull%5D "/fbcode/torchrec/distributed/model_tracker/types.py") * Maps to `EmbdUpdateMode.LAST` to capture the most recent momentum values Differential Revision: D76868111
…meta-pytorch#3144) Summary: X-link: meta-pytorch#3144 This diff extends the Model Delta Tracker to support two new tracking modes: `MOMENTUM_DIFF` and `ROWWISE_ADAGRAD`, which enable tracking of rowwise optimizer states for more sophisticated gradient analysis. Differential Revision: D76918891
Summary: Make DeltaStore generic to allow use case specific custom implementations internal General Context: We are in the process of transition to a unified DeltaTracker and this is 1/n diffs representing changes towards the transition. Specific Context: DeltaTracker utilizes Memstore to preserve and compact lookups extracted during embedding lookups. As part of transitioning to a common DeltaTracker, we are adding a generic DeltaStore. Memstore will extend from Generic DeltaStore, allowing both MRS and OSS DeltaTrackers to be easily integrated into training frameworks. Differential Revision: D80614364
