Exam 18: Distributed Process Management

The negotiation mechanism makes sure that the destination system does not refuse to accept the migration of a process to itself.

_________ is when only one process may use a resource at a time and no process may access a resource unit that has been allocated to another process.

Caching is not permitted in the Sprite system.

The __________ method immediately grants the request of an older transaction by killing a younger transaction that is using the required resource.

It is the delay in communication, coupled with the lack of a common clock, which makes it much more difficult to develop mutual exclusion mechanisms in a distributed system compared to a centralized system.

A __________ is a special control message used by an algorithm.

Mutual exclusion, deadlock, and starvation are not issues that are faced in a distributed system.

With __________ a deadlock exists if there is a closed loop, or cycle, in the graph that depicts process dependencies.

With __________ , all processes cooperate in the deadlock detection function.

With the __________ strategy, the entire address space at the time of migration is transferred

When a process is migrated, it is necessary to destroy the process on the source system and create it on the target system.

__________ orders events in a distributed system without using physical clocks.

A _________ exists between two processes if they exchange messages.

When two or more processes compete for the use of system resources, there is a need for a mechanism to enforce __________ .

The transfer of a sufficient amount of the state of a process from one computer to another for the process to execute on the target machine is __________ .

A ________ is the path or means by which the message is transferred.

Interest in the concept of process migration grew out of research into methods of load balancing across multiple networked systems.

_________ is a technique in which a decision is made dynamically whether a given resource allocation request could, if granted, lead to a deadlock.

The decision to migrate must be reached jointly by two Starter processes, one on the source node and one on the destination node.

In a fully ___________ one node is designated as the control node and controls access to all shared objects.
