Available vs single-step debug distributed server, n change 1In general, the distributed service side to start a lot of processes, once the process is more, single-step debugging becomes very difficult, resulting in server development basically by playing log to find the problem. The usual development game logic also has to open a lot of processes, not only start slow, and find problems and inconvenient, in a heap of logs to check the problem, it feels very bad,

When you write a new expression like this:Widget * PW = new widget;There are two functions called:
compiler encounters such a statement:String * PS = new string ("Memory Management ");The code generated by it is more or less similar to the following code (for more details, see article 8 and article 10 of Objective C ++, as well as comments in my article counting object .) :Void * Memory = // get unprocessed memoryOperator new (sizeof (string); // String objectCall string: string ("Memory Management") // InitializationOn * memory; // memory in progress// ObjectString * PS = // PS pointerStati
.placement NewSometimes you do want to call the constructor directly.It makes no sense to call a constructor on an existing object, because the constructor is used to initialize the object, and an object can be initialized only once given its initial value. but sometimes you have some (raw) memory that has already been allocated but not processed, and you need to construct an object in these memory. You can use a special operator new, which is called

As programmers do not have the right to bypass the new operator like this using constructors, but the compiler does so .That's why if you want to make a heap-based object, be sure to use the new operator.T

In the cluster system, the process arrival time and the amount of resources required for the new arrival process are unpredictable. Therefore, process placement and migration are very important. Due to the unpredictability in the cluster system, processes are sometimes placed on unsuitable machines, and Process Migration gives the system a chance to make up for such errors. Using better algorithms to place new processes on appropriate nodes for execut
