class popxl.ReplicatedTensorSharding(value)

Enum type to specify whether to shard tensors over replicas.

Off = 'Off'

Tensors will not be sharded over replicas.

On = 'On'

Tensors will be sharded over replicas.

class popxl.TensorLocation(storage=TensorStorage.OnChip, replicated_tensor_sharding=ReplicatedTensorSharding.Off)

Class that describes the memory characteristics of one or multiple tensors.

Parameters
Return type

None

__init__(storage=TensorStorage.OnChip, replicated_tensor_sharding=ReplicatedTensorSharding.Off)
Parameters
Return type

property replicated_tensor_sharding: popxl.tensorlocation.ReplicatedTensorSharding
property storage: popxl.tensorlocation.TensorStorage
class popxl.TensorStorage(value)

Enum type to specify whether to store tensors on-chp in tile memory, or in Streaming Memory.

OffChip = 'OffChip'

Store the tensor in Streaming Memory.

OnChip = 'OnChip'

Store the tensor in tile memory.
