Abstract
Providing host-based error detection capabilities in a remote execution device is disclosed. A remote execution device performs a host-offloaded operation that modifies a block of data stored in memory. Metadata is generated locally for the modified of block of data such that the local metadata generation emulates host-based metadata generation. Stored metadata for the block of data is updated with the locally generated metadata for the modified portion of the block of data. When the host performs an integrity check on the modified block of data using the updated metadata, the host does not distinguish between metadata generated by the host and metadata generated in the remote execution device.
