    1212  * Assume that we got 3 machines in our testbed, now we have to edit /etc/hosts on each node.[[BR]]

    152152=== 3. Conclusion ===
    153153 * This is the most simple parallel computing environment, just for teaching and testing.
    154  * Do not expect that your job can be sbmitted to it and run faster! They are just virtual machines.
     154 * Do not expect that your job can be submitted to it and run faster! They are just virtual machines.
     155 * Establish MPICH2 parallelized computing environment will become very difficult when the number of nodes growing up and up.[[BR]]
     156   So, it is very important for using DRBL and Clonezilla well to help us build this parallelized environment.[[BR]]
     157   I will try to use DRBL to build a 10+ nodes parallelized machine later.
