内存碎片导致应用不断被杀的问题
内存分配一波三折,小结一下: 1.      先尝试快速分配,其中会从不同的zone以及迁移类型上去尝试,失败的话就进入慢速分配,里面会再划分单页面从pcp上分配以及多页面从伙伴系统中分配。 2.      尝试慢速分配,一般流程就是唤醒内存页面回收线程,然后尝试低水位分配 -> 忽略水位分配 -> 压缩内存分配 -> 直接回收内存分配 -> oom killer杀死线程分配 -> 压缩内存分

So they has to use some resources in the process.nIn order to make it more convenient, they will put some resources in a box big enough, each resource has its ID and level of priority. When they want a kind of resources, they will give its ID and get it from the box. If there are several ones available in the box, they will get the highest priority ones. If there are still several ones available, they will get the one which puts in the box first. n输入:nnnThe input will consist of several cases, please deal with till the end of file. Each case contains a integer N(0

Channel Allocation
DescriptionnnWhen a radio station is broadcasting over a very large area, repeaters are used to retransmit the signal so that every receiver has a strong signal. However, the channels used by each repeater must be carefully chosen so that nearby repeaters do not interfere with one another. This condition is satisfied if adjacent repeaters use different channels. nnSince the radio frequency spectrum is a precious resource, the number of channels required by a given network of repeaters should be minimised. You have to write a program that reads in a description of a repeater network and determines the minimum number of channels required.nInputnnThe input consists of a number of maps of repeater networks. Each map begins with a line containing the number of repeaters. This is between 1 and 26, and the repeaters are referred to by consecutive upper-case letters of the alphabet starting with A. For example, ten repeaters would have the names A,B,C,...,I and J. A network with zero repeaters indicates the end of input. nnFollowing the number of repeaters is a list of adjacency relationships. Each line has the form: nnA:BCDH nnwhich indicates that the repeaters B, C, D and H are adjacent to the repeater A. The first line describes those adjacent to repeater A, the second those adjacent to B, and so on for all of the repeaters. If a repeater is not adjacent to any other, its line has the form nnA: nnThe repeaters are listed in alphabetical order. nnNote that the adjacency is a symmetric relationship; if A is adjacent to B, then B is necessarily adjacent to A. Also, since the repeaters lie in a plane, the graph formed by connecting adjacent repeaters does not have any line segments that cross. nOutputnnFor each map (except the final one with no repeaters), print a line containing the minumum number of channels needed so that no adjacent channels interfere. The sample output shows the format of this line. Take care that channels is in the singular form when only one channel is required.nSample Inputnn2nA:nB:n4nA:BCnB:ACDnC:ABDnD:BCn4nA:BCDnB:ACDnC:ABDnD:ABCn0nSample Outputnn1 channel needed.n3 channels needed.n4 channels needed.

Stack vs Heap Allocation
[size=14px]rnHow the memory of the computer is organized for a running program? When a program is loaded into memory, it is organized into three areas of memory, called segments: the text segment, stack segment, and heap segment. The text segment (sometimes also called the code segment) is where the compiled code of the program itself resides. This is the machine language representation of the program steps to be carried out, including all functions making up the program, both user defined and system.rnrnThe remaining two areas of system memory is where storage may be allocated by the compiler for data storage. The stack is where memory is allocated for automatic variables within functions. A stack is a Last In First Out (LIFO) storage device where new storage is allocated and deallocated at only one ``end'', called the Top of the stack. This can be seen in Figure 14.13. rn figure14.13.gifrnrnWhen a program begins executing in the function main(), space is allocated on the stack for all variables declared within main(), as seen in Figure 14.13(a). If main() calls a function, func1(), additional storage is allocated for the variables in func1() at the top of the stack as shown in Figure 14.13(b). Notice that the parameters passed by main() to func1() are also stored on the stack. If func1() were to call any additional functions, storage would be allocated at the new Top of stack as seen in the figure. When func1() returns, storage for its local variables is deallocated, and the Top of the stack returns to to position shown in Figure 14.13(c). If main() were to call another function, storage would be allocated for that function at the Top shown in the figure. As can be seen, the memory allocated in the stack area is used and reused during program execution. It should be clear that memory allocated in this area will contain garbage values left over from previous usage.rnrnThe heap segment provides more stable storage of data for a program; memory allocated in the heap remains in existence for the duration of a program. Therefore, global variables (storage class external), and static variables are allocated on the heap. The memory allocated in the heap area, if initialized to zero at program start, remains zero until the program makes use of it. Thus, the heap area need not contain garbage.rn小结:rnStack: automatic variables within functionsrnHeap: global variables (storage class external), and static variables[/size]rnrn大侠讨论一下啊。rn

SQLite入门与分析(五)---Page Cache之并发控制
写在前面:本节主要谈谈SQLite的锁机制,SQLite是基于锁来实现并发控制的,所以本节的内容实际上是属于事务处理的,但是SQLite的锁机制实现非常的简单而巧妙,所以在这里单独讨论一下。如果真正理解了它,对整个事务的实现也就理解了。而要真正理解SQLite的锁机制,最好方法就是阅读SQLite的源码,所以在阅读本文时,最好能结合源码。SQLite的锁机制很巧妙,尽管在本节中的源码中,我写了...
