how to make raspberry pi supercomputer

-linaro-arm-linux-gnueabihf-raspbian-x64 are used for 64-bit machines. Each cross-compilation tool has a bin directory in the directory to enter, execute./arm-linux-gnueabihf-gcc-v to view the GCC version. I use ARM-RPI-4.9.3-LINUX-GNUEABIHF here because the GCC version on the board is now 4.9.3 3. Start compiling 3.1 Enter the Linux kernel directory: $ CD ~/RASPBERRY/LINUX-RPI-4.4.Y $ kernel=kernel7 $ make

To make it easier to connect and control the Raspberry Pi over the network, use SECURECRT to connect the Raspberry Pi over the network. 1, on the Raspberry Pi through the terminal comma

/gpio$1/direction echo setting pi high echo 1 >/sys/clas S/gpio/gpio$1/value A few notes"1" If you write a shell script on windows (and then transfer to the Raspberry Pi using the FTP tool), you must save it in UNIX format. The shell script ends with \ n per line, not \ r \ n in Windows. You can use the notepad++ format conversion feature to complete the chan

make these aliases take effect later. Command lines starting with "#" are commented out. To enable them, you only need to remove "#" And wait until your Raspberry Pi starts to activate these settings. The. bash_aliases file is also referenced here. By default, this file does not exist: If [-f ~ /. Bash_aliases]; then.~ /. Bash_aliasesFi The if condition is used

NOOBS SETUPTo get started with Raspberry Pi need an operating system. NOOBS (New out of the Box software) are an easy operating system Install manager for the Raspberry Pi.How to GET and INSTALL NOOBSBUY A preinstalled SD CARDThe easiest-to-get NOOBS is to buy a SD card with NOOBS preinstalled, available-for￡4 at the Swag Store. Alternatively, if you have a SD ca

downside is that no matter how big your card is, its partitioning depends on the operating system, which wastes some space. The command is as follows: DD if=raspybin bs=1kb count=4000 of=/dev/sdxx here xx is your SD card, don't make a mistake! Otherwise lose hard drive data at your own risk. I purchased a 8G SD card, after installing the raspybin image of Pi, insert the SD card slot, connect the m

to note that Openhab also runs on older Raspberry Pi, but there is a problem with slow processing and the use of z-wave devices. You need to upgrade to the latest version of the Raspberry Pi and add z-wave. However, without the need for z-wave, you can safely ignore the problem and use

Problem: "Unable to connect because the target computer is actively rejecting" The first time to make Raspberry Pi, because the Raspberry Pi can not directly connect the monitor, so use remote connection, here, I use a network cable to connect the way, notebook and

download it after you select the desired version. Download the https://nodejs.org/dist/v4.2.1/node-v4.2.1-linux-armv7l.tar.gz or use your PC, sftp to Raspberry Pi. Decompress the tar xvzf node-v4.2.1-linux-armv7l.tar.gz to move the mv node-v4.2.1-linux-armv7l/usr/local/bin configuration to make the node and npm commands valid in all directories, or to create a l

first, the simplest method on the Raspberry Pi is to use apt-get and then give control to the Openhab user.sudo apt-get install openhab-addon-binding--hr Openhab:openhab/usr/share/openhabNext, you need to tell Openhab to load the binding and configure all the required variables. go to the configuration folder, copy a copy of Openhab-default.cfg, and name it openhab.cfg. Open the file, search for hue, and r

This article is not a compiled installation of node, it is said to take a long time, so at first I was rejected. This article shows how to deploy the compiled execution file for Ndoe. Node's official Web download directory itself has compiled executable files for arm. Address is here: HTTPS://NODEJS.ORG/DIST/V4.2.1/Choose the right version Download the appropriate version for the Raspberry Pi, the appropria

Front-facing:1. hostname Please change from default Raspberrypi to test.comsudo nano /etc/hostnamePlease change the raspberrypi in the file to test.com2. Change the IP address of the Raspberry Pi to static, in this case 172.16.0.68, the gateway exits to 172.16.0.1sudo nano /etc/dhcpcd.confAt the bottom of the document, add the following settings:interface eth0static ip_address=172.16.0.68/24static routers=1

Although the Raspberry Pi has gcc, you can compile the C + + program, but if the project is large, compiling with the Raspberry Pi will waste a lot of time, we can compile the program on the PC, then pass the executable file to the Raspberry

Raspberry Pi (Raspberry Pi) is a mini computer that is about the size of a credit card. It was originally designed for students to design a low-cost computer programming aids, because of its rich diversity people to apply it to a variety of projects.As a DIY King Pi, SD card

Preface Because I have been very interested in linux, I started an experiment with Raspberry Pi and set up a simple php server to run typecho. However, the process is extraordinary, and almost every step is stuck. in addition, compared with WordPress, typecho has less data, which makes the process of solving the problem a little difficult. The first is the Raspberry
