What is it about?
Mutex locks that are recoverable, designed to survive crash failures, and NUMA-aware, designed to scale and perform well on multi-socket (or multi-processor) systems, are solely developed in the literature. This work presents a technique that makes any recoverable lock a NUMA-aware one.

Why is it important?
Recoverability enables the main feature of using persistent memory, and NUMA-awareness increases performance on multi-processors. Persistent memory and multi-processors are being highly developed and widely adopted, respectively.
