obtain all available supervisor first, infer that the supervisor available standard is whether there is a spare slot, that is, whether all supervisor.slots.ports specified port is occupied, and then calculate the need to allocate a few woker. Since a woker corresponds to a port, and of course the collection of this information is from zookeeper, we now analyze the core code of the allocation:Workermaker.javaNote that result is the slot required for this job. Prior to incoming only know the numb

1. Project requirements of the banking dispatch system Simulation to achieve the logic of banking scheduling system, the specific requirements are as follows: Ø There are 6 business windows in the Bank, window 1-4 is a normal window, window 5th is a quick window, and 6th window is the VIP window. Ø There are three types of customers: VIP customers, ordinary customers, fast customers (handling such as electricity and water charges, such as customer ser

Calculation timePriority computing is no longer focused on the scheduler's choice of candidate processes, and as long as the status of the process changes, it is possible for the core to compute and set the dynamic priority of the process:A) Create a processIn Wake_up_forked_process (), the child processes inherit the dynamic precedence of the parent process and are added to the ready queue in which the parent process resides.If the parent process is not in any ready queue (for example, it is a

. Imagelocalitypriority: Rate based on whether the pod is operating on the host. Imagelocalitypriority will determine whether the required mirror of the pod is already on the host, and return a 0-10 rating based on the size of the existing mirror. Returns 0 if a desired mirror is not present on the host, and if a partial mirror image is present on the host, the value is determined based on the size of the mirrors, and the higher the image, the more the score is. Nodeaffinitypriority (new feature

Network Office has become the trend of modern enterprise development. This paper mainly expounds the function module of the transceiver management system based on B/s structure and how to use ASP and SQL Server to solve some related technologies, including the security of the system.

(ChannelName, durable, false, false, NULL);When this is set, the server receives the message and writes the message to the hard disk immediately, preventing the sudden server from hanging up and the data being lost. However, if the server has just received the message, has not yet been able to write to the hard disk, it hangs up, this still cannot avoid the loss of the message. Second, fair dispatch The previous example can be implemented to send a

In addition to the \ (master\) , each ninja has and has only one ancestor. To keep it private and to enhance the leadership of the Ninja, all instructions related to their work are always sent by

There are three types of queue Main:Tasks execute serially on your application's main thread Concurrent:Tasks start executing in FIFO order, but can run concurrently. Serial:Tasks execute one at a time in FIFO order (1) Serial queues (Serial Queue), also known as private scheduling queue, is generally used for Synchronous access to specific resources. We can create any number of serial queues as needed. Each serial queue is concurrent. (2) Parallel queue, also known as global

problems, for example, retain delegate causes loop reference; or assign delegate is not properly managed, and a wild pointer is displayed. This type of problem can discourage common developers. Ios4 introduces block programming and gcd (Grand Central Dispatch) task queue management. Here we will not go to the layout to introduce the boring syntax. If you have any requirements, please read the documents by yourself. First, we try to use block + GCD t

FastCGI the dispatch thread resolves PHP, is the static property (memory) in PHP between threads shared? Because fastcgi runs a PHP script, the memory is not released, and then the next request is scheduled to be processed, then the value of the static variable stored after the PHP run, the next PHP will get it? Such asclass A { public statis $var; public static function init() { $var+=1; } }A::init(); When the next PHP runtime A::init(); , is the

Whole and part Remember this proverb, "the whole is greater than the sum of the parts"? If one individual event is combined into an interacting whole, the result will be much greater than the sum of the individual's actions. Procedures are the same. As new methods are added to the program, the possible control flow of the entire program increases rapidly. For large programs, the situation will soon be out of control. Like an absurd and incredible trick, sometimes the end result you get is not

time. We know that the disk for sequential write batch data is much more efficient than the random write, each write very little data, resulting in a large number of random write, and if we slow down the frequency of checkpoint, multiple random pages may be composed of a sequential batch write, the efficiency greatly improved. In addition, checkpoint will perform fsync operations, a large number of fsync may cause system IO congestion, reduce system stability, so checkpoint can not be too frequ
