+B.      ONEMPI Architecture
+ONEMPI is a software package, and it de-pends on DRBL to deploy PC cluster environment. We are just run the ONEMPI script which is build a PC cluster [[br]]
+quickly. We employ to combine DRBL with ONEMPI to build a message-passing interface system environment. At first we need to install configuration the [[br]]
+DRBL software which is easy to install on operating system. Then, we run the ONEMPI script by using super user when the DRBL is installed on ours system. [[br]]
+The two steps is finished, users can execute and compile mpi pro-gramming on the system environment. The ONEMPI script is automatically produce the [[br]]
+“mpd.hosts” on yours home directory, and the mpd.hosts is to record all nodes hostname and Pro-cessor numbers. However, the ONEMPI is achievement to [[br]]
+realize the complicate installation process. However, users can use the instruction “mpdboot -n * -f mpd.hosts” on yours home direc-tory, and the * is [[br]]
+node numbers. [[br]]
+The Figure 1 shows ONEMPI architecture, and the ONEMPI script has two significance files as follows: [[br]]
+(1) The “mpi_install.sh” script is configuration to install software package (g++, fort77, gcc, mpich2, etc.) in the system, and create the “mpd.conf” [[br]]
+file to ours home directory. [[br]]
+(2)     The “drbl_mpi_patch” script is to adjust the DRBL software, including the public key, creating the mpd.hosts file and DRBL redeploy clients, etc. [[br]]

+
+(3)     We can run ONEMPI script file in the terminal command as follows: [[br]]
+       Step 1: sudo ./install [[br]]
+       (default : /opt/drbl-mpi) [[br]]
+       Step 2: cd /opt/drbl-mpi/ [[br]]
+       Step 3: sudo ./drbl_mpi.sh [[br]]
+
+C.      System Environment Architecture [[br]]
+Table 1 shows the software packages about the diskless cluster. There are one server node and two client nodes in our system environment. Server and  [[br]]
+clients have one Intel 2 Quad CPU Quad CPU    Q9550 @ 2.83GHz and 8 Gbytes of memory. Ours system is Ubuntu 10.10 version. [[br]]
