event sequences. It is aimed at the shortest path problem of the directed graph of the fence network, which can be decoded by any problem described by the implied Markov model.24. A logistic regression model is an exponential model that combines different factors that affect probabilities. As with exponential models (such as the maximum entropy model), their training methods are similar and can be implemented using iterative algorithm GIS and improved iterative algorithm IIS.25.MapReduce uses t

One, the distinction between time and efficiencyClustermeans that all devices work together to perform the same function, and that each device's functionality is complete, but it seems to be a device in the outside world.　　DistributedAll of the equipment assembled, together to form a system, work together with each other, while doing their own corresponding work, but all the functions are not on one device, but by different devices, but by a device as a unified access point and coordination poin

In the past few days, we have been doing a data migration task between clusters. What we need to do is to give a task file, and each row in the file corresponds to a source: A migration task in the form of DeST (both source and DEST are file names) with tens of millions of tasks. The task is actually very simple. read each row, parse the source and DEST, read the source from the source cluster based on the given cluster information, and write it to the Dest of the target cluster. Has gone throug

still many problems. The current research on parallel processing controllers is generally focused on parallel processing of robot kinematics and dynamic models. It is designed based on the ing features of parallel algorithms and multi-processor structures. That is, by decomposing a given task, several subtasks are obtained and listed. The data-related flow chart enables concurrent processing of each sub-task on the corresponding processor. Due to the

Before talking about multithreading, it is necessary to clarify the differences and relationships between processes and threads. The process is being executed on the computer.Program(An active program), and each process has its own independent memory space and a group of system resources. The memory space and resources used by these programs are independent, and each program runs for its own task without interfering with each other. The thread concept is proposed based on the process, which

, in the vortex, there is no need to carry that great pressure. 28. Important to the body, safety first. 29. Don't boast of others, don't swear after others. 30. Chinese cigarettes taste thick and spicy. Smoke is not suitable for you. Liquor can be used for liquor training, and beer is broken. 31. When walking, the waist should be straight. The man's waist pole holds up the soul of the man. The man cannot walk straight, and most of them have psychological problems. Otherwise, it is very dark

Recently, I wrote a multi-thread download program similar to thunder (I use asynchronous socket. Strictly speaking, it is not a multi-thread method and should be considered multi-task). I have summarized the following requirements, the main features are as follows: Download feature (Core) Allows you to download objects from specified URLs. Supports custom Refer, Cookie, and other headers. Query download speed and file size Supports file caching. After the download is complete, check whethe

I want to buy iPhone 4. In fact, more attention is paid to the development of IOS 4. The NFS application master imitates the merge Effect of IOS 4 tasks, which is not only poor, but can only be merged in one way. Splitting has not yet been implemented. In general, the following things are required to achieve a job merging effect similar to iOS 4: 1. A set of abstract good classes. My design is: taskitem (including the item of the task panel and the actually running task pointer, And the taskitem

the Fork/join framework to optimize the execution performance of the merge algorithm, instantiating the split subtasks into multiple forkjointask tasks into the queue for execution, and by fork/ The join framework dispatches these tasks between multiple forkjoinworkerthread threads. As shown in the following:Following is the merge algorithm code after using the Fork/join framework, note that the code for merging two ordered sets into a new ordered se

to the application's address space.Disadvantages of Cache IO:Data is required to perform multiple copies of data in the application address space and the kernel during transmission, and the CPU and memory overhead of these data copy operations is very large.Processes and ThreadsFor the operating system, a task is a process, such as open a browser is to start a browser process, open a notepad started a Notepad process, open two Notepad started the two Notepad process, open a word started a word
