With the promotion of industry institutions, the new routing protocol OpenFlow will provide users with unprecedented management methods to reduce their necessary work intensity in terms of network control. OpenFlow uses a software-defined network activity. That is to say, you can ignore the specific circumstances of the underlying hardware, define the traffic directl

Original article link Inter-process communication refers to the Process Communication and information exchange between multiple processes. Linux IPC is basically inherited from the UNIX platform. It mainly includes the original Unix IPC, System v ipc, and socket-based IPC. In addition, Linux also supports posix ipc. System V, BSD, POSIX System V is one of the earliest commercial releases of UNIX operating systems. It was initially developed by att (American Telephone Telegraph) and was fi

research institutions to obtain UNIX source code for research and development by distributing licenses. The most important event in this phase is that the Unix author uses the C language to rewrite the Unix source code, making UNIX very portable. The second stage was in 1980s, a rich period of Unix development. After the development of UNIX to version 6, att continued to develop its internal Unix Version 7, at the same time, an external release version has also been developed, but it is called

Therefore, you must specify the current path because you first find the path .

BOINC(Berkeley open Infrastructure for Networkcomputing, Berkeley Open Network Computing platform) isone of the pre-mainstream distributed computing platforms,designed to provide researchers with a powerful computing power that brings together a large number of PCs around the world. Up to January 25, 2008, BOINC has approximately 549,000 active hosts worldwide and provides an average of about 852TeraFLOPS (

few seconds of the WAN. There may be other tasks that we want to perform during this period of time;(2) We can use this technology to establish multiple connections simultaneously; This technology is popular with web browsers;(3) Since using Select to wait for a connection to be established, we can specify a time limit for select so that we can shorten the timeout for connect.Non-blocking Connect details:(1) Although the socket is non-blocking, if the server connected to the same host, then whe

What is SparkSpark is an open-source cluster computing system based on memory computing that is designed to make data analysis faster. Spark is very small, developed by Matei, a team based in the AMP Lab at the University of California, Berkeley. The language used is Scala, the core part of the project's code is only 63 scala files, very short and concise. Spark is an open-source cluster computing environment similar to Hadoop, but there are some diff

pooling to pre-allocate processes and reuse of processes to reduce system consumption and time waits caused by process duplication;Pros: Eliminate the overhead of new customer requests arriving to create processes;Disadvantage: Pre-estimating the number of customer requests (determining the size of the process pool)Systems originating from the Berkeley kernel have the following features:All derived child processes call ACCEP () to listen for the same

state copy once, and to the device to wait for the queue to hang once, and epoll as long as a copy, and the current to wait for the queue is hung only once (in Epoll_ At the start of wait, note that the wait queue here is not the device waiting queue, just a epoll internally defined wait queue. This can also save a lot of overhead. 5, UNIX and Linux BSD relationship description both Linux and BSD are UNIX-like operating systems. We can find that Linux and BSD have different lineages by readin

, an important Unix branch Although Bell belongs to ATT, ATT adopts a more open attitude towards Unix at this time. In addition, Unix is written in high-level C language and theoretically portable, as long as the original Unix Code is obtained and the original Source Code is modified for the characteristics of a large host, Unix may be transplanted to another different host header. So after 1973, Unix was developed in collaboration with academia! The most important contact was the cooperation wi

understand the cap theory is to imagine two nodes on each side of the partition. Allowing at least one node to update the state results in inconsistent data, i.e. the loss of C nature. If the node on the partition side is set to not be available for data consistency, the A property is lost. Unless two nodes can communicate with each other, both C and a are guaranteed, which can lead to the loss of P-Properties.This theorem originates from the computer scientist Eric Brour of the University of C
