As we demonstrated in ' A gentle introduction to Parallel computing in R ' one of the great things about R was how easy it is To take advantage of parallel processing capabilities to speed up calculation. In this note we'll show how to move from running jobs multiple cpus/cores to running jobs multiple machines (for even LA Rger scaling and greater speedup). Using the technique on Amazon EC2 even turns your credits card into a supercomputer.

to tell them that this is no problem, weave will automatically connect, after their service starts, we can also tell weave to connect multiple peers, you can provide multiple IP addresses, separated by a space.Above the HOST1:Docker Attach $sshAbove the HOST2:Docker Attach $sshThen ping each other, and you'll see that the network is connected.Here's a look at the specific deployment process1.

Background information:Previously, because the price of AWS EC2 more expensive and rented other foreign small vendors VPS, after using more than 3 years, found that the AWS EC2 Price is much cheaper than the VPS currently in use.The T1.MICRO model of the most ideal Japanese node of the global line and speed, the choice of 3-year long-term contract price of about 2500 yuan, less than 900 yuan a year, so it i

Open Stack Compute Infrastructure (Nova) Nova is the computational organization controller in the OpenStack cloud. All activities that support an instance (instances) lifecycle in the OpenStack cloud are handled by the Nova. This makes Nova a platform for managing computing resources, networks, certifications, and scalability requirements. However, the Nova itself does not provide any virtualization capabilities, instead it uses the Libvirt API to interact with the supported hypervisors. Nova p

I believe everyone has used Amazon's EC2 service, but I guess we know VPC is not a lot, let's take a look at the official introduction:Amazon Virtual Private Cloud (Amazon VPC) lets you to provision a private, isolated section of the Amazon Web Services (AWS) Cloud where you can launch AWS, in a virtual network, you define.The services supported by VPC are:EC2RdsS3SimpledbElbIn the Amazon series, I'll tell you about the installation and configuration

Google, which has always targeted individual users, still makes a big fuss over the cloud computing applications of individual users. Yahoo's cloud computing is similar to Google's.

OpenStack Cloud computing platform to help service providers and businesses implement cloud infrastructure services similar to Amazon EC2 and S3 (infrastructure as a service, IaaS). The OpenStack contains two main modules: Nova and Swift, a virtual server deployment and Business Computing module developed by NASA, and a distributed cloud storage module

This morning, there was a massive outage in Windows Azure China Data Center (Shanghai), which is still not fully functional. Post one of the most serious downtime events since Windows Azure landed in China.Domestic and foreign major public cloud vendors have been down, and each outage event in the industry caused a public cloud security controversy.

algorithm is that fault tolerance and extensibility are not good. Fault tolerance refers to whether the whole system can run correctly and efficiently when one or several servers in the system become unavailable, and extensibility refers to whether the whole system can run correctly and efficiently when a new server is added.Now assume that a server is down, in order to fill the vacancy, to remove the outage server from the numbered list, the followi

, immediately the network VIP and the intranet VIP bound to Server2, and the server2 of MySQL switch to the main library. At this time because the outside VIP has been transferred to the Server2,web request will be sent to Server2 Nginx. Nginx detects a server1 outage and no longer forwards the request to the Server1 php-fpm. After the SQL request as usual sent to the local Atlas,atlas write operation sent to the intranet VIP, read operation sent to S

An RDB maximizes the performance of Redis: The only thing the parent process has to do when saving an Rdb file is to fork out a child process, and the child process will handle all subsequent save work, and the parent process does not have to perform any disk I/O operations. An RDB recovers a large data set faster than AOF. rdb persistence disadvantage If you need to avoid data loss in the event of a ser

In the process of using the computer, it is unavoidable to encounter a lot of sudden failures, the cause of these failures may be caused by software, but also may be caused by hardware failure, or other factors ... So how do our junior computer users respond to these events, and don't panic, see below: Suffer a power outage Phenomenon Analysis: This is a sudden "power failure" caused.
