But the reality is brutal, many software itself stability to be promoted, the machine hardware resources upgrade will touch the cost, therefore in the cluster environment, has the redundancy, makes the implementation simple service restart becomes the most realistic choice. This is not a difficult thing in itself, there are many ways to implement it, such as adding action or commands to Zabbix or nagios alarms, or writing scripts to execute on a scheduled task. But what this article is going t

basic operation of the time spent, generally using microseconds to measure the speed of single-chip microcomputer, 51 single-Chip machine cycle includes 12 clock oscillation cycle, that is, if the 51 microcontroller using 12MHz crystal, then the implementation A machine cycle requires only 1μs, and if you are using a 6MHz crystal, it takes 2μs to perform a machine cycle. 2. Instruction cycle refers to the time required for a single-chip microcomputer to execute an instruction, generally using a

I = 1; I {For (Int J = count-1; j> = I; j --){If (pdata [J] {Itemp = pdata [J-1];Pdata [J-1] = pdata [J];Pdata [J] = itemp;}}}} Void main (){Int data [] = {10, 9, 8, 7, 6, 5, 4 };Bubblesort (data, 7 );For (INT I = 0; I Cout Cout } Reverse Order (worst case)First round: 10, 9, 8, 7-> 10, 9, 7-> 10, 7, 9-> 7, 10, 9, 8 (three exchanges)Round 2: 7, 10, 9-> 7, 10, 8-> 7, 8, 9 (2 exchanges)First round: 7, 8, 10, 9-> 7, 8, 9, 10 (switching once)Cycles: 6Num

. The clock cycle can only be set to the time of the most time-consuming instruction) [Compare the paging mechanism of memory management to improve memory utilization.] Intel 1978 in 8086 requires multiple (usually 3 ~ 10) clock cycle to execute a command. A more advanced processor can keep every clock 2 ~ The execution rate of four commands. In fact, each instruction takes a long time from the beginning to the end, about 20 or more cycles, however,

/2* (n-1) *n.Now notice that we give the definition of the O method:If there is a constant K and a starting point n0, so that when n>=n0, there is f (n) Learn maths well, for programming math is very important ... ）Now let's look at 1/2* (n-1) *n, when K=1/2,n0=1,g (n) =n*n, 1/2* (n-1) *n=o (g (n)) =o (n*n). So the complexity of our program loop is O (n*n).Look at the exchange again. From the table following the program, you can see that the loops in both cases are the same and the exchange is d

other, but in some specific cases, we should first select some kind of statement to quickly implement the loop design. If the following conditions are true:(1) Number of cycles known(2) The number of cycles is unknown, but the cyclic conditions are clear when entering the cycle(3) The number of cycles is unknown, and the loop condition is unknown when entering t

Specint_rate 2000 simultaneous execution of multiple instances (instances) and the ability of the system to perform multiple compute-intensive integer operations at the same time can well reflect such things as database servers, Performance of multi

The first part: Introduction to Algorithms[1946:john von Neumann, Stan Ulam, and Nick Metropolis, all in the Los Alamos scientific Laboratory, cook up the Metropol is algorithm, also known as the Monte Carlo method.] John von Neumann,stan Ulam and Nick Metropolis, a three scientist at the National Laboratory of the United States in 1946, were invented as the Monte Carlo method. Its specific definition is: i

She is responsible for creating a departure schedule. There was n flights that must depart today, the i-th of them was planned to depart at the i-th minute of the day. Metropolis Airport is the main transport hub of Metropolia, so it's difficult to keep the sch

microprocessor architecture in load and store memory, if the access address is an integer multiple of N, n Bytes can be operated at a time (n = 2 ^ m), but if the n Bytes of the operation are in the address, the remainder of N is not 0, two or more clock cycles are required, especially when the address crosses the cache line, the performance impact is more serious. For example, if you want to read the 4 byte int variable, if the physical address of t

Here is the program that we designed to send the characters that will be displayed to the TFTLCD module.Second, STM32 FSMC working principle (FSMC full name "Static memory controller")1, FSMC function IntroductionConvert the AHB transmission signal to the appropriate external device protocolMeet timing requirements for accessing external devicesAll external memory shares the address, data, and control signals of the controller output, and each external device can be distinguished b

column read and write command must have an interval with the row valid command, this interval is defined as TRCD, that is, RAS to CAS delay (RAS to CAS latency), this is very well understood, After the address line to send the line address, to wait until the line address stable positioning and then send the address, TRCD is an important time parameter of SDRAM, the relevant values refer to the corresponding chip hardware manual. Usually trcd in the number of clock

compare the algorithms by the number of cycles.2. Exchange Law:The procedure for exchanging is the clearest and simplest, which is compared and exchanged each time with the following elements of the current element one by one. Copy Code code as follows: #include void Exchangesort (int* pdata,int Count) { int itemp; for (int i=0;i{ for (int j=i+1;j{ if (Pdata[j]{ itemp = PData; PData = Pdata[j]; PDATA[J] = itemp; } }

constant, so the loop executes all the time, and the break statement can be used inside the loop to jump out of the loop.2. In general, when designing a looping structure, it is possible to use the for, while, does while three statements, and three statements can be converted to each other, but in some specific cases, we should first select some kind of statement to quickly implement the loop design. If the following conditions are true:(1) Number of cycles
