The text discusses the comparison between shared memory and message passing.
Message passing provides communication and synchronization mechanisms.
System calls are only made to define the common memory space.
A system call is made every time a message is exchanged.
Message passing is faster and appropriate for exchanging a lot of information.
Shared memory is slower and appropriate for exchanging few data.
The text analyzes some design aspects of message passing.
The state of blocking or unblocking must be considered when a process sends or receives a message.
When a process sends a message, it can either wait for the receiver to receive it or continue running.
Message passing requires careful synchronization to avoid deadlocks.
Conditions for resource allocation must meet certain requirements.
These requirements were demonstrated as necessary by Coffman et al. in 1971.
One process can use a resource at a time.
No process can access a resource that belongs to another process.
Mutual exclusion is necessary for resource allocation.
The conditions were cited by multiple authors, including Silberschatz, Stallings, and Tanenbaum.
The conditions are important for ensuring efficient and fair resource allocation.
The conditions help prevent deadlock and resource starvation.
The conditions are relevant to operating systems and computer science.
Coffman et al.'s work is foundational in resource allocation research.
