concurrent access. One way to do so is known as a critical section or critical region. This protected section cannot be entered by more than one process or...

to enter the critical section. Entrance to the critical section is granted for process P0 if P1 does not want to enter its critical section or if P1 has...

critical section at the same time, the algorithm will allow only one process in, based on whose turn it is. If one process is already in the critical...

execute some particular program segment known as critical section. Processes' access to critical section is controlled by using synchronization techniques...

"tickets" to control which thread of execution is allowed to enter a critical section. The basic concept of a ticket lock is similar to the ticket queue...

to minimize the worst-case length of time spent in the scheduler's critical section, during which preemption is inhibited, and, in some cases, all interrupts...

it subcritical. A mass may be exactly critical at a particular temperature. Fission and absorption cross-sections increase as the relative neutron velocity...

execution never enters a critical section while a concurrent thread of execution is already accessing said critical section, which refers to an interval...

constitutes a critical section that must be synchronized by mutual exclusion. If code and processor instructions in critical sections of code that access...

Critical theory is a social, historical, and political school of thought and philosophical perspective which centers on analyzing and challenging systemic...

read-side critical sections, which are normally delimited by rcu_read_lock and rcu_read_unlock. Any statement that is not within an RCU read-side critical section...

control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system...

continuation/restart logic. The length of any critical section that needs to be interrupted. Entry to a critical section restricts concurrent data structure access...

and solved by Courtois et al. Suppose we have a shared memory area (critical section) with the basic constraints detailed above. It is possible to protect...

protect critical sections of code. During the execution of such a critical section, all interrupt handlers that cannot execute safely within a critical section...

up both forks or wait, never holding exactly one fork outside of a critical section. To accomplish this, Dijkstra's solution uses one mutex, one semaphore...

exclusion algorithms designed to prevent concurrent threads entering critical sections of code concurrently to eliminate the risk of data corruption. Lamport...

as mutexes, semaphores, and critical sections are all mechanisms by which a programmer can ensure that certain sections of code do not execute concurrently...

choosing the highest priority of any interrupt that ever entered the critical section, the priority inversion problem could be solved without locking out...

Critical race theory (CRT) is an academic field focused on the relationships between social conceptions of race and ethnicity, social and political laws...

operations in a critical section. Strictly, independent operations can then be carefully permitted to overlap their critical sections, provided this does...

the function at a critical point is a critical value. More specifically, when dealing with functions of a real variable, a critical point is a point in...

In release consistency model, the action of entering and leaving a critical section are classified as acquire and release and for either case, explicit...

degradation due to the idle wait times spent by the CPUs in kernel-level critical sections. Software lockout is the major cause of scalability degradation in...
