Abstract

Some implementations disclosed herein provide techniques and arrangements for recovery of data stored in memory shared by a number of processors through information stored in a cache directory. A core of a processor may initiate access (e.g., read or write) to particular data located in a first cache that is accessible to the core. In response to detecting an error associated with accessing the particular data, a location in the processor that includes the particular data may be identified and the particular data may be copied from the location to the first cache.
