The server-side program generally has the following processes: bind, listen, and accept. Then there are various operations after the client and the server are connected.
In contrast, the client program is relatively simple. You only need to obtain the sock_id first and connect it with the corresponding sock. The others are as follows.
Server code:
1 #include
Client code:
1 #include
The call is as follows:
Server startup:./rlsd
Client Access:./

RAID 0 to raid 6. In addition, there are some basic raid-level combinations, such as raid 10 (a combination of RAID 0 and RAID 1) and raid 50 (a combination of RAID 0 and RAID 5. Different RAID levels represent different storage performance, data security, and storage costs. However, we usually use the following raid forms.
(1) RAID 0
(2) RAID 1
(3) RAID 0 + 1
(4) RAID 3
(5) RAID 5
There are three main factors to choose a raid level: availability (data redundancy), performance, and

This article mainly describes the Python access to crawl Web pages commonly used commands related information, the need for friends can refer to the following
Python access common commands for crawling Web pages
Simple crawling of Web pages:
Import urllib.request url= "http://google.cn/" Response=urllib.request.urlopen (URL) #返回文件对象page = Response.read ()
To save the URL directly as a local file:
Import urllib.request url= "http://google.cn/" Response=urllib.request.urlopen (URL) #返回文件对象pag
urllib. parse import urllib. request url = "http://www.google.cn/webhp" values = {"rls": "ig"} data = urllib. parse. urlencode (values) theurl = url + "? "+ Data # Create a request object req = urllib. request. request (theurl) # get the data returned by the server response = urllib. request. urlopen (req) # process data page = response. read ()
There are 2 common methods, geturl (), info ()
Geturl () is set to identify whether there is server-side U
Data replication service is added to the data management section of the latest gt3.9.5. According to the official website, its function is mainly to generate local copies, that is, to use rft to transfer the files needed in the grid to the local, and automatically register a copy with rft.
The following is an introduction to the original article:
The Data Replication Service (DRS) is a technical preview provided with the Globus Toolkit 3.9.5 and first appears in the GT 3.9.5 beta release. the
