PRAM and Processor Consistency
Pipelined RAM
- A Relaxing of Causal Consistency by removing the causality:
- Writes from a SINGLE process are received by all other processes in the order in which they were issued
- Writes from different processes may be seen in a different order by different processes.
- So all processors agree to order of writes issued by processor P
Processor
- PRAM
- Writes from a single process to a single location must be agreed upon by all processors
- Writes to different locations need not be agreed upon
