When processes share a semaphore variable mutex?

When processes share a semaphore variable mutex, they use it to synchronize access to a shared resource by controlling which process has permission to access the resource at a given time. This helps prevent conflicts and ensures that only one process can access the shared resource at any given point.


What is smart pointer in C plus plus?

A smart pointer is a resource handle. There are three types of smart pointer: unique, shared and weak (std::unique_ptr, std::shared_ptr and std::weak_ptr, respectively). A unique pointer "owns" the resource it refers to and will destroy that resource when the pointer falls from scope. Unique pointers can be moved (transferring ownership between the pointers) but they cannot be copied. Aside from that, they behave exactly as a "naked" pointer would and incur no runtime overhead. Unique pointers are the ideal method of implementing RAII (resource acquisition is initialisation) because they provide the basic guarantee (no resource leaks). Shared and weak pointers work together to provide shared ownership. A shared pointer "owns" the shared resource while a weak pointer does not. In order to access the shared resource via a weak pointer, the weak pointer must first be converted to a shared pointer to assume temporary ownership. If the original shared pointer falls from scope during this time, the resource's lifetime is extended until the temporary shared pointer falls from scope. Weak pointers can also be used to break circular references between shared pointers. Although there is a runtime cost in using shared pointers, the cost is close to optimal compared with manual solutions using "naked" pointers, but with a much reduced maintenance burden. In multi-threaded applications, shared resources are often inevitable, but are best avoided whenever possible. However, writing lock-free code makes code difficult to maintain, thus shared pointers can often provide a convenient compromise.


Difference between priority inheritance and priority ceiling protocol?

priority inheritance: when a job blocks one or more high priority jobs, it ignores its original priority assignment and executes its critical section at the highest priority level of all the jobs it blocks.priority ceiling: gives each shared resource a predefined priority ceiling. When a task acquires a shared resource, the task is hoisted (has its priority temporarily raised) to the priority ceiling of that resource. It will not see whether the job has been blocked or not, simply it raises to the priority of the shared resource.


What are the main problem of shared use?

The main problems of shared use include lack of privacy, potential conflicts over resource allocation, difficulties in coordinating schedules and responsibilities, and challenges in maintaining cleanliness and orderliness in shared spaces.


What is the significance of the tragedy of the commons in game theory and how does it impact decision-making in shared resource management?

The tragedy of the commons in game theory highlights the problem of individuals acting in their own self-interest, leading to the depletion of shared resources. This concept impacts decision-making in shared resource management by emphasizing the need for cooperation and regulation to prevent overuse and ensure sustainability.


What is the difference between a common resource and a public good in terms of their availability and usage by the general population?

A common resource is a shared resource that can be depleted if overused, such as a fishery. A public good is a non-excludable and non-rivalrous resource, like clean air, that is available to everyone and cannot be easily depleted.


Used or shared by everyone in a group?

A common resource or shared benefit used or accessed by all members in a group is often referred to as a "common pool resource." Examples include public parks, clean air, or a community garden. These resources require cooperation and responsible management to prevent overuse or depletion.
