Abstract

Managing operations in a first compute node of a multi-computer system. A remote write may be received to a first address of a remote compute node. A first data structure entry may be created in a data structure, which may include the first address and status information indicating that the remote write has been received. Upon determining that the local cache of the first compute node has been updated with the remote write, the remote write may be issued to the remote compute node. Accordingly, the first data structure entry may be released upon completion of the remote write.
