Most research in the area of memory models revolves around: Designing a memory model that allows a maximal degree of freedom for compiler optimizations while still giving sufficient guarantees about race-free and (perhaps more importantly) race-containing programs. Proving program optimizations that are correct with respect to such a memory model.
The BSP model is also well-suited for automatic memory management for distributed-memory computing through over-decomposition of the problem and oversubscription of the processors. The computation is divided into more logical processes than there are physical processors, and processes are randomly assigned to processors.
The (IBM) SPMD programming model assumes a multiplicity of processors which operate cooperatively, all executing the same program but can take different paths through the program based on parallelization directives embedded in the program; and specifically as stated in [6] [5] [4] [9] [10] “all processes participating in the parallel ...
The causal consistency model can be refined into four session guarantees. [11] They can be summarised as follows: Read Your Writes: If a process performs a write, the same process later observes the result of its write. Monotonic Reads: the set of writes observed (read) by a process is guaranteed to be monotonically non-decreasing.

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 ...
The Java memory model was the first attempt to provide a comprehensive memory model for a popular programming language. [6] It was justified by the increasing prevalence of concurrent and parallel systems, and the need to provide tools and technologies with clear semantics for such systems.
Model-based design provides an efficient approach for establishing a common framework for communication throughout the design process while supporting the development cycle . In model-based design of control systems, development is manifested in these four steps: modeling a plant, analyzing and synthesizing a controller for the plant,
