Essential Questions and Answers on Read Memory Barrier in "COMPUTING»SOFTWARE"
What does RMB do?
RMB ensures that every processor in the system reads the most up-to-date data from memory and prevents it from being reordered.
When should I use RMB?
RMB should be used whenever a read operation needs to happen before another instruction, such as when reading from shared memory or when data needs to be read before writing a new value.
How does RMB work?
RMB works by flushing any memory operations that have not yet completed and then waiting for all processors in the system to complete their pending operations before beginning a new cycle. This ensures that each processor reads the same values, preventing out-of-order execution.
Final Words:
RMB is an important tool for ensuring data consistency and correctness in multi-processor systems. By forcing all processors in the system to flush their pending operations, it guarantees that each will read the same values from shared memory locations at any given time and prevents errors due to out-of-order execution.
