h1{color:green}. Wakame-os

Wakame-os is the Cluster Level Infrastructure Operating System. It is designed to be very simple to handle resources of cluster beyond the different cloud infrastructures. (Amazon EC2, Wakame-vdc, and etc in the future)

h2. Example: Running a remote code




  require 'wakame'

  process = Wakame::Process.setup(:credential => {:user => 'your_name'})

  

  process.fork {

    print "Running code on the remote!\n"

  }





h2. Example: Launch a new instance




  require 'wakame'

  credential = {:user => 'your_name'}

  

  instance = Wakame::SyncRpc('instance')

  instance.create_instances(credential)





h2. Example: Configure instances & launch

You can build "the Hybrid-cloud," and use it in your code.

Difinition of specification have a logical name.

h3. config/cloud_catalog.rb




...(snip)...

  

  cc.credential 'amazon_account' do |c|

    c.access_key        = 'YOUR_ACCESS_KEY'

    c.secret_access_key = 'YOUR_SECRET_ACCESS_KEY'

  end


...(snip)...

  cc.spec 'aws_fedora_core_8' do |s|

    s.credential = 'amazon_account'

    s.driver = 'aws'

    s.requirement do |r|

      r.image_id = 'ami-84db39ed'

    end

  end

...(snip)...





h3. fork_sample.rb

You can use the logical name of specification in your code.




  require 'wakame'

  process = Wakame::Process.setup(:credential => {:user => 'your_name'},

                                  :spec_name => 'aws_fedora_core_8')

  

  process.fork {

    print "Running code on the remote fedora core 8!\n"

  }





h3. instance_sample.rb




  require 'wakame'

  credential = {:user => 'your_name'}

  

  instance = Wakame::SyncRpc('instance')

  instance.create_instances(credential, 'aws_fedora_core_8')





h2. Example: PI calc




  require 'rubygems'

  require 'wakame'

  require 'rational'

  

  credential = { :user => 'yam' }

  

  process = Wakame::Process.setup( :credential => credential,

                                   :spec_name  => 'unknown'

                                   )

  

  queue   = Wakame::Queue.setup

  

  # How many compute?

  dist = 30

  challange = 1000000

  

  dist.times { |no|

    process.fork(no, challange, queue) { |no, challange, queue|

      hit  = 0

  

      challange.times {

        x = rand

        y = rand

        hit += 1 if x*x+y*y<1.0

      }

      queue.push [no, Rational(hit, challange)]

    }

  }

  

  print "Process were distributed. Waiting results...\n"

  

  rat = 0

  dist.times { |i|

    data = queue.pop

    print "Arrival result #{i+1}/#{dist} from node number. #{data[0]} -> #{data[1]}\n"

    rat += data[1]

  }

  print "Final result. PI = #{(rat * Rational(4, dist)).to_f}\n"
