This chapter defines how the EMulatR emulator enforces ordering, visibility, and completion in an otherwise weakly ordered execution model.

 

Alpha AXP does not guarantee memory ordering by default. Instead, ordering is established explicitly through serialization instructions. This chapter explains:

•Why serialization exists and what it guarantees

•What is serialized (and what is not)

•How barriers interact with the pipeline — stall mechanics, release conditions

•The full MemoryBarrierKind instruction set

•How this applies to SMP systems

 

This chapter is foundational to correctness in SMP synchronization, atomic operations, device I/O, exception precision, and PAL mode transitions.
