| | 137 | * '''Repeat the operations above to all the other nodes.'''(If you got 10+ machines, the will be a "big work") |
| | 138 | * If any error occurs, just remove /root/.ssh/known_hosts, and re-ssh. |
| | 139 | * '''Step 6''' : Start MPICH2 |
| | 140 | * The easist way to setup a parallelized computing environment is to issue: |
| | 141 | {{{ |
| | 142 | root@client-01:~# mpdboot -n 3 -f /root/mpich2-1.0.7rc1/mpd.hosts |
| | 143 | }}} |
| | 144 | * Check the mpich2 nodes. |

| | 152 | === 3. Conclusion === |
| | 153 | * 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. |
