process. The communication between threads is mainly through shared memory, the context switch is very fast, the resource cost is low, but it is easy to lose data compared with the process. 3. Co-process The coprocessor is a user-state lightweight thread, and the scheduling of the coprocessor is completely controlled by the user. The coprocessor has its own re

replicate? I don't see Skynet.send/call/rawcall support for replication control, see Vim-t _send. The underlying default processing is: Direct replication for LUA strings, no replication for Lightuserdata, error for other types) The Dispatch_message will be the engine of the service (message driver), which is the message handler function (Vim-t _dispatch_message, executed by the underlying worker when it gets a message in ctx.mq). The bottom layer is called by the worker thre

There are two ways to use a channel. · The coprocessor can attempt to put data into the channel and, if the channel is full, suspends the co-process until the channel can put the data into it. · The coprocessor can attempt to request data to the channel, and if the channel has no data, it s

asynchronous Library (aiohttp. I use it to write some small data capture tasks that are indeed fast. I will show you how to do this. Basic concepts of asyncioAsyncio is an asynchronous IO library introduced in python3.4. You can also install it through the pypi of python3.3. It is quite complicated, and I will not introduce too many details. Instead, I will explain what you need to know and use it to write asynchronous code. In short, there are two things you need to know: collaborative program

coprocessor executes asynchronously in the child shell, just as the command uses the end of the "" control to establish a connection between the execution shell and the coprocessor using a two-way pipeline. The co-processing format is as follows:Coproc [NAME] command [redirections]This creates a co-processing named "name". If "name" is not specified, then the default name is "Coproc". If "command" is to gi

system context switches to coprocessor 2 before the value assigned to ' x ' is calculated in the 1. So, the Association 2 gets the initial value of ' X ' (still 0), and calculates ' x + 1 '. Then the system context is switched back to the co-process 1. Now, the coprocessor 1 assigns the computed value 1 to ' x ', so ' x ' equals 1. Then, the process 2 continues to execute and calculatesThe value (still 1)

The most common arm directives include the following six categories:1. Data processing instruction: arithmetic and logical operation of data in register2. Program Status Register processing instruction: MRS MSR3. Jump instruction: B and BL4. Load/store instruction: Instructions for data transfer between registers and memory5. Abnormal interrupt instruction: SWI and BKPT6. coprocessor directive: MRC MCR=-------------------------------------------------

make such a query, often through a system like hive, pig and other systems for the MapReduce calculation, this method is not only a waste of machine computing resources, but also because of high latency to make the application overshadowed. As a result, in the industry and community, the HBase secondary indexing scheme became the most vocal feature of HBase's new version (0.96).Rough analysis of the current technology, the approximate scenario can be summed up in such two categories:1.
