ABSTRACT:
A method for enabling concurrent, overlapping data moves associated with separate data clone operations of different memory cloners. A first data is being moved from its source to a destination. The first data is tagged with the address of the first destination to identify the data, and the data is sent over the fabric with the destination tag. A second data is concurrently (or subsequently) routed over the fabric to a next destination, while the first data is still in on the fabric. The second data is also tagged with its specific destination tag, which is different from the destination tag of the first data routed. Thus, the two sets of data overlap on the on the fabric but are each uniquely identified by their respective destination tag. Both the first and second data may also be tagged with a respective unique identifier (ID) associated with the memory cloner that initiated the particular clone operation. The unique IDs are re-used, and the number of bits for the unique ID is selected so that the first sequentially-numbered clone operation completes prior to a new clone operation requiring a unique ID.
