P4L3 – Distributed Shared Memory 01 – Lesson Preview In this lesson we will talk about distributed shared memory systems for DSMs. These are an an example of applications that perform certain distributed state management operations. Now in this lesson a lot of what we will talk about will be in
1. Shared virtual memory mapping. distributed manager algorithms, and in particular shows that a class of distributed manager algorithms can retrieve Both Info table and PTable have page-based locks. They are used to synchronize the local page faults (i.e., fault handler operations) and remote
The page-based approach is generally considered clearer and easier to program in. However, its implementation for C/C++, e.g. in Treadmarks [1], requires direct communication 4An alternate world view which shares some characteristics with the shared-memory paradigm is that of tuple spaces.
2. Distributed shared memory?DSM paradigm provides process with shared address space? Primitives for shared memory:- Read(address)- Write(address , data)?Shared memory paradigm gives the systems illusion of physically shared memory?DSM refers to shared memory paradigm
So distributed shared memory essentially provides a virtual abstraction of process sharing pages while underneath, it is running over a message passing network. There’s a distributed shared memory can be implemented over a message passing interface and also vice-versa.

Distributed shared memory (DSM) is a software support for distributed memory architectures, that allows the system to look (to the application software) as if it were a shared memory architecture. The applicable memory coherence protocols reflect the limitations in the performance of DSM systems
When this situation occurs, a page must be evicted from memory to make room for the needed page. To a large extent, the choice of which page to evict can be made using traditional virtual memory algorithms, such as some approximation to the least recently used algorithm.

Distributed Shared Memory abbreviated as DSM is the implementation of shared memory concept in distributed systems. The DSM system implements the shared memory models in loosely coupled systems that are deprived of a local physical shared memory in the system. We present Resilient Distributed Datasets (RDDs), a dis-tributed memory abstraction that lets programmers per-form in-memory computations To achieve fault tolerance efciently, RDDs provide a restricted form of shared memory, based on coarse-grained transformations rather than ne-grained
