We propose a method called Node Replication (NR) to implement any concurrent data structure. The method takes a single-threaded implementation of a data structure and automatically transforms it into a concurrent (thread-safe) implementation. The result is designed to work well with and harness the power of modern servers, which are complex Non-Uniform Memory Access (NUMA) machines with many processor sockets and subtle performance characteristics. Using NR requires no expertise in concurrent data structure design, and the result is free of concurrency bugs. NR represents a paradigm shift of how concurrent algorithms are developed: rather than designing for a data structure, we design for the architecture.
