Conway's Game of Life with KDB+ and Enterprise Components

For information on what this is, please have a look at this post at the Formalized Mathematics blog.

Setup

Download KDB+, yak and DEVnet's Enterprise Components:

  $ wget https://github.com/exxeleron/enterprise-components/releases/download/ec-3.2.3/ec_v3.2.3_DemoSystem_Linux32bit_Lessons_1-5.tgz
  $ tar -xvf ec_v3.2.3_DemoSystem_Linux32bit_Lessons_1-5.tgz

Set up directory structure expected by the configuration:

  $ mkdir bin
  $ ln -s ../DemoSystem/bin/ec/ bin/ec
  $ ln -s ../DemoSystem/bin/q/  bin/q
  $ ln -s ../DemoSystem/bin/yak/  bin/yak
  $ ln -s <path to the LifeWithEC clone bin/life
  $ ln -s <path to the LifeWithEC clone>/etc/ etc

The last command has to be done from the same directory where the bin directory was created above.

Source the environment

  $ source etc/env.sh

Check if yak is working

  yak info life

Yak distributed with Enterprise Components is a 32bit application. If you are running a 64-bit system you may have to install some compatibility libraries.

Start the admin process

  $ yak start life
  Starting components...
  
        life.admin                      OK

Start the grid cells

  $ yak start grid
  Starting components...
  
        grid.cell_0                     OK
        grid.cell_1                     OK
        grid.cell_2                     OK
  ...
        grid.cell_96                    OK
        grid.cell_97                    OK
        grid.cell_98                    OK
        grid.cell_99                    OK

Check the status of the grid processes

  $ yak info grid
  uid                pid   port   status      started             stopped            
  -----------------------------------------------------------------------------------
  grid.cell_0        2600  17000  RUNNING     2014.05.27 14:02:49                    
  grid.cell_1        2606  17001  RUNNING     2014.05.27 14:02:49                    
  grid.cell_10       2652  17010  RUNNING     2014.05.27 14:02:51
  ...
  grid.cell_98       3431  17098  RUNNING     2014.05.27 14:04:11                    
  grid.cell_99       3434  17099  RUNNING     2014.05.27 14:04:11

Check the port the life.admin process is listening at

  $ yak info life
  uid                pid   port   status      started             stopped            
  -----------------------------------------------------------------------------------
  life.admin         2579  17100  RUNNING     2014.05.27 14:01:56

You can connect to the life.admin component with KDBstudio or a similar application to have a look at the result of the simulation. Alternatively you can use the a web browser and the (elm application)[https://github.com/SKolodynski/LifeWithEC/tree/master/elm].

All processes can be stopped with

  $ yak stop \*
