Enabling OMP on PC

In cs426, we use OpenMP both on PC and in SciCloud. If you want to try OpenMP on you laptop or PC, you may have to install some software as following.

1. get CodeBlock IDE and MinGW
2. include C:\MinGW\bin to system path
3. install mingw32-pthreads-w32 using C:\MinGW\bin\mingw-get.exe
4. In codeBlock, Settings>>compiler>>linker setting>>link library=C:\MinGW\bin\libgomp-1.dll
5. In codeBlock, Settings>>compiler>>compiler settings>>other options= -fopenmp

You may need to restart your computer to apply the new configuration.

creating a new network in SciCloud

To create a new network:

1. networks>create network>subnet=192.168.0.0/24
2. create routers>select external network to attach the routers>create an interface to the new network
3. Now a new instance can be attached to the new network. However, it could not resolve the URL, a DNS servers in /etc/resolv.conf need to be change. Add "nameserver 8.8.8.8" to the /etc/resolv.conf 

Analog reader

An one day project to create an analog reader for some scientific instruments. Objective of the project is to make an interface between any analog sensors to a computer. Her we choose the following ingredients;

-Arduino Uno to read analog signals and send messages to a computer through a serial port
-pyserial to get the serial input to python environment
-matplotlib
-Bokeh to visualise the analog signal in real-time

What we have done!
1. Make sure the Arduino IDE and driver are already installed
2. Python2.7 and pyserial must be installed. Here we use Anaconda and pyserial need to be installed by "$conda install pyserial" on Windows and "pip install pyserial" on Unix.
3. Install Bokeh
4. Then we made a simple implementation for communication between Uno and PC by using the codes here.
