EREW
EREW, or Exclusive Read Exclusive Write, is a memory-access discipline used in the PRAM family of theoretical parallel computation models. It defines how a set of processors can access a shared global memory in a parallel step.
In an EREW PRAM, no memory cell may be accessed by more than one processor in a
EREW is the most restrictive widely studied PRAM variant, and it serves as a baseline for analyzing
The model is primarily a theoretical tool used in complexity theory and the study of parallel algorithms.
