legate.core.Runtime.create_store_from_buffer

Runtime.create_store_from_buffer(self, Type dtype, shape: Shape | Collection[int], data, bool read_only) → LogicalStore

Creates a Legate store from a Python object implementing the Python buffer protocol.

Parameters:

• dtype (Type) – Type of the store’s elements

• shape (Shape | Collection[int]) – Shape of the store

• data (object) – A Python object that implements the Python buffer protocol

• read_only (bool) – Whether the buffer of the passed object should be treated read-only or not. If False, any changes made to the store will also be visible via the Python object.

Returns:

Logical store attached to the buffer of the passed object

Return type:

LogicalStore

Raises:

BufferError – If the passed object does not implement the Python buffer protocol

Notes

It’s the callers’ responsibility to make sure that buffers passed to this function are never partially aliased; i.e., Python objects A and B passed to this function must be backed by either the exact same buffer or two non-overlapping buffers. The code will exhibit undefined behavior in the presence of partial aliasing.
