| 25 | | , integrates Newton`s equation of mo-tion, is an open source code, and runs on single processors or parallel programming with using message-passing [[br]] |
| 26 | | interface. The LAMMPS source is widely applied in the semiconductors, biomolecular, polymers, coarse-grained and microscopic, etc. It has been used [[br]] |
| 27 | | to simulate in the chemistry and semiconductor research. The LAMMPS has lots of library to use, modify, or extended LAMMPS in your choose. [[br]] |
| 28 | | In past few years, PC cluster are more and more popular in high performance computing be-cause of computing ability. However, it is difficult for [[br]] |
| 29 | | the administrator manage lots of computers, to deploy the system environmental and to configure the installation of the cluster. The DRBL-ONEMPI provides [[br]] |
| 30 | | a way to manage the pc cluster environ-ment, such as the installation of the cluster, the deployment system environment, the user man-agement, the system [[br]] |
| 31 | | monitor and easy to use it. [[br]] |
| 32 | | |
| 33 | | The DRBL-ONEMPI has two components package, including DRBL and ONEMPI. The DRBL is a diskless or systemless environment for client machines and an open source solution to managing the deployment of the GNU/Linux oper-ating system across many clients. Hence, we have an ideal plan for running MPI programming on the diskless environment and so to exploit ONEMPI. The ONEMPI make user avoid complicated the MPICH2 installation process. However, we com-bine DRBL with ONEMPI which rename DRBL-ONEMPI. In general, the pc cluster is diffi-cult to manage and deploy environment. However, we use DRBL-ONEMPI to manage and execute mpich2 on our computing environment. The user just enters some instructions on command-line that accomplish diskless environment. |
