The Importance Of Inter Process Communication
Inter process communication is the mechanism of sharing data between multiple processes Johan (2001). These enable the program to manage many user’s request at the same time. Inter processes communication helps the programmer to handle the activities within different processes. According to Johan (2001) IPC makes it possible for individual application to help another application. In this paper IPC is discussed on how it allows the processes to use semaphore, monitor, sleep and awake mutex, mutual exclusion, critical regions race condition, and barriers to share data and memory. Race conditions Steve (1996) suggest that Race condition occurs when a system attempt to processes two or more processes that access the same data at the same time, …show more content…
Johan (2001) suggest that critical region terminates in a fixed amount of time. This critical region is usually used when programs that are multi-threaded are having some conflictions changes to data. The diagram bellow illustrate the mutual exclusion by using the critical region Mutual exclusion Mutual exclusion is the process whereby the access to the shared resources is limited. According to Burns (1993) in mutual exclusion the corruption occurs when more than one processes perform its operation only on a single resource, there operating system make sure that this kind of problem doesn’t occur. The following diagram shows the example of mutual exclusion: Here two nodes, I and i+1 have been excluded Sleep and Wakeup Sleep and wakeup is one of the solution to the mutual exclusion situation. “The process is put to sleep when it is unable to get in the critical region, therefore it is woken up if the critical section is no longer available” Mullender …show more content…
They are mostly used in order to control access to shared memory. According to Mullender (2005) Semaphores techniques are used for synchronising the activities of the operating system. File descriptors are used in order to implement the semaphores, therefore creation of semaphores are not atomic. A race condition occurs when two or more processes use the semaphore simultaneously. Burns (1993) suggest that the availability of the resource to be used is showed by the creation of semaphores and they are implemented through

The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.

1070 Words | 5 PagesQuestion 1: We learned that when calling subprograms or functions that we can pass data to the subprogram or function by ‘value’ or by ‘reference’. Describe what each approach is, how it works and what the potential security disadvantage is when passing parameters by reference. An easy way to view the difference between pass by value and pass by reference is to use the explanation on (Stack Overflow, 2008). This is a great way to visualize the difference as well as the potential security issues. "Say I want to share a web page with you.

To be able to absolutely exploit ever larger computing platforms, trendy HPC applications and system computer code should be able to tolerate inevitable faults. traditionally, MPI implementations that incorporated fault tolerance capabilities are restricted by lack of modularity, measurability and value. an application employing a MPI implementation that has fault tolerance services is best equipped to adapt to current and next generation HPC systems. sadly several of those implementations offer sophisticated interfaces to the applying user or need them to make a decision between production

314 Words | 2 Pages3.1.1 Dual Clock In this technique it is assumed that delay misses rarely happens, then circuit schedules are designed using minimal delays for critical paths. Pair of alternate clocks, fast and slow, is used. The system normally operates at the fast clock however, when an error is noticed, computation for the input values which is causing error is restarted at the slower clock. Under the premise that delay errors occur for small number of input values, the system can switch back to the faster clock on the next input value.
