Questions and Answers

What is the primary purpose of local caches in page-based DSM systems?

To minimize the latency of accesses to remote nodes (correct)

To replicate pages for load balancing

To manage the ownership of pages

To store the entire distributed memory

Which node is responsible for managing access to a page in a page-based DSM system?

A randomly selected node

The home node for the page (correct)

Any node that has a copy of the page

The node that most frequently accesses the page

Study Notes

Distributed Shared Memory Systems

Each node contributes a portion of its main memory pages to the Distributed Shared Memory (DSM) layer.
Local caches are maintained to minimize latency of accesses to remote nodes, improving performance.
All nodes are responsible for managing a portion of the distributed memory.
Each node tracks page ownership and access rights, with a designated "home node" for each page managing accesses and ownership.
Explicit replication can be used to assist with load balancing and improve performance.
Replication can also address reliability concerns, providing redundant access to data in case of node failure.
