Transactional memory model [7] is the combination of cache coherency and memory consistency models as a communication model for shared memory systems supported by software or hardware; a transactional memory model provides both memory consistency and cache coherency. A transaction is a sequence of operations executed by a process that ...
There are several memory-consistency models for SMP systems: Sequential consistency (all reads and all writes are in-order) Relaxed consistency (some types of reordering are allowed) Loads can be reordered after loads (for better working of cache coherency, better scaling) Loads can be reordered after stores; Stores can be reordered after stores

Processor consistency is one of the consistency models used in the domain of concurrent computing (e.g. in distributed shared memory, distributed transactions, etc.).. A system exhibits processor consistency if the order in which other processors see the writes from any individual processor is the same as the order they were issued.
The alternative definition of a coherent system is via the definition of sequential consistency memory model: "the cache coherent system must appear to execute all threads’ loads and stores to a single memory location in a total order that respects the program order of each thread". [4]
The DRF1 memory model [10] provides SC for DRF and allows the optimizations of the WO (weak ordering), RCsc (Release Consistency with sequentially consistent special operations), VAX memory model, and data-race-free-0 memory models. The PLpc memory model [11] provides SC for DRF and allows the optimizations of the TSO (Total Store Order), PSO ...
Causal Consistency is “Available under Partition”, meaning that a process can read and write the memory (memory is Available) even while there is no functioning network connection (network is Partitioned) between processes; it is an asynchronous model. Contrast to strong consistency models, such as sequential consistency or linearizability ...
