A deadlock happens when two threads each wait for a resource held by the other, so neither can proceed. The easiest way to illustrate this is with two locks: object locker1 = new object(); object locker2 = new object(); new Thread (() => { lock (locker1) { Thread.Sleep (1000)...

1) GPU scaling in AMD Catalyst This method enabling GPU scaling is a little old as most PCs use Radeon settings. Here are the steps: Select the AMD Catalyst Control Center after right-clicking on the desktop, in the drop-down menu. Hover over to the option My Digital Flat Panels on the...
A livelock is similar to a deadlock, except that the states of the processes involved in the livelock constantly change with regard to one another, none progressing. Livelock is a special case of resource starvation; the general definition only states that a specific process is not progressing. ...
Learn, what is process synchronization in OS (Operating System) along with examples. You will also find how it works, essential sections, types, why it's important and more.
So, what is a “deadlock”? Etymologically, it can be divided into two root words: “dead” and “lock”. We could intuitively understand it as alock that leads to a dead end… In relational database management systems, locking is a mechanism that happens every time. Actually, we can ...
What exactly is going on in the deadlock report? it feels like txn 2 is trying to acquire a lock it already has. why? this is the only txn in my code that accesses the pings table. why does this code deadlock at all? Update: Adding table schema: CREATE TABLE `pings` ( `id` va...
We need a system which can act as an intermediary and manage all the processes and resources present in the system. AnOperating Systemcan be defined as aninterface between user and hardware. It is responsible for the execution of all the processes, Resource Allocation,CPUmanagement, File Manageme...
1.7 We have stressed the need for an operating system to make efficient use of the computing hardware. When is it appropriate for the operating system to forsake this principle and to“waste” resources? Why is such a system not really wasteful?答:单用户系统,它应该最大化地为用户使用,一...
A spurious interrupt may result in system deadlock or other undefined operation if the ISR doesn't account for the possibility of such an interrupt occurring. As spurious interrupts are mostly a problem with wired-OR interrupt circuits, good programming practice in such systems is for the ISR to...
