This interesting paper starts by summarizing the logic of shared memories across local area network (LAN) nodes. Shared memory systems in parallel computing are very popular and highly valued due to the efficiency in parallelization outputs and memory-intensive computation performance. The process of granting access to remote memories remains a prominent problem in parallel and distributed computing, where standard approaches may retain vulnerabilities with respect to security and the cost of access, which creates an unavoidable tradeoff and substantial compromises. The particular approach introduced and discussed in this paper suggests a password-driven protection and access process to remote memory blocks.

The approach introduces the key concept of handles, which is used to manage the access permissions based on primary and secondary passwords. This helps balance the tradeoff between security and the cost of access granted to users. The experimental results demonstrate the proposed approach’s efficiency and the success level that can be achieved. As an academic in the field, I plan on taking this paper into consideration for teaching parallel and distributed computing.
