Example scenarios

• A simple session with one client and one slave, one job with one task:
  Master is started...
  1. Slave=>Master (after slave starts)

           <Message Type="M_SLAVE_STATUS">
            <SlaveStatus>Ready</SlaveStatus>
            <SlaveInfo>
              <OS>Linux</OS>
              <CPU>PIII/850</CPU>
              <Memory Unit="MB">256</Memory>
              <Disk Unit="MB">1024</Disk>
              <IP>195.158.16.40</IP>
            </SlaveInfo>
           </Message>
         

  2. Client=>Master (after client starts, creates new job)

           <Message Type="M_CLIENT_STATUS">
             <JobID>
               <Name>Dumb</Name>
               <Number>-1</Number>
             </JobID>
             <ClientStatus>On</ClientStatus>
             <IP>122.132.11.43<
           </Message>
         

  3. Master=>Client (master returns full JobID)

           <Message Type="M_JOB_STATUS">
            <JobID>
             <Name>Dumb</Name>
             <Number>1</Number>
            </JobID>
            <JobStatus>
             <TasksDone>0</TasksDone>
             <TasksRunning>0</TasksRunning>
             <TasksWaiting>0</TasksWaiting>
            </JobStatus>
           </Message>
