Abstract
Systems and methods for concurrent reading and writing in shared, persistent byte-addressable non-volatile memory is described herein. One method includes in response to initiating a write sequence to one or more memory elements, checking an identifier memory element to determine whether a write sequence is in progress. In addition, the method includes updating an ingress counter. The method also includes adding process identification associated with a writer node to the identifier memory element. Next, a write operation is performed. After the write operation, an egress counter is incremented and the identifier memory element is reset to an expected value.
