ContinuousBatchingKVCache
@register_passable(trivial)
struct ContinuousBatchingKVCache[dtype_: DType, kv_params_: KVCacheStaticParams]
Wrapper for the ContinuousKVCache of a given layer in the transformer model.
This abstracts the Pointer indirection for accessing the ContinuousKVCache for a given batch entry.
THIS IS THE TYPE THAT IS PASSED TO KV PROJECTION AND FLASH ATTENTION KERNELS.
Parameters
- dtype_ (
DType): The dtype of the kv-cache. - kv_params_ (
KVCacheStaticParams): The kv-cache static parameters.
Fields
- blocks (
NDBuffer[dtype_, 4, MutableAnyOrigin, DimList.__init__[Dim, Dim, Dim, Dim](Dim(-31337), Dim(-31337), Dim(kv_params_.num_heads), Dim(kv_params_.head_size)), _strides_from_shape[DimList.__init__[Dim, Dim, Dim, Dim](Dim(-31337), Dim(-31337), Dim(kv_params_.num_heads), Dim(kv_params_.head_size)), skip=1]()]): - cache_lengths (
NDBuffer[DType.uint32, 1, MutableAnyOrigin]): - lookup_table (
NDBuffer[DType.uint32, 1, MutableAnyOrigin]): - max_seq_length (
UInt32): - max_cache_length (
UInt32):
