Using Cluster Systems

This section explains the usage methods common among the Next Generation Simulation Technology Education and the Wide-Area Coordinated Cluster System for Education and Research. See the page for each system for details of specific functions.

Logging In

* Computer Systems for the Next Generation Simulation Technology Education*/

• Wide-Area Coordinated Cluster System for Education and Research

Setting Up the Developmental Environment

To compile a program, it is necessary to set environment variables depending on the parallel processing MPI and the compiler. For example, if you plan to use an Intel MPI as the parallel computing MPI and an Intel compiler as the compiler, set the environment variables using the following commands shown below. Note that the Intel MPI and the Intel compiler are set as the session defaults.

$ module load intelmpi.intel

You can also use the following commands to set the environment variables.

To change the environmental settings, execute the following command to delete the current settings and set the new environment variables.

$ module unload environmental_settings

For example, if you change the Intel MPI and the Intel compiler to the Open MPI and the Intel compiler, execute as follows.

$ module unload intelmpi.intel
$ module load openmpi.intel

Setting Up the Software Usage Environment

When using software, it is necessary to change the environment variables depending on the software package to be used. For example, use the following command to set the environment variables to use Gaussian.

$ module load gaussian09-C.01

You can also use the following commands to set the environment variables.

• You must be a Type A user to use ANSYS, ABAQUS, Patran, DEFORM-3D, GAUSSIAN, CHEMKIN-PRO, and MATLAB.
• To apply for registration as a Type A user, see:

http://imc.tut.ac.jp/research/form.

To cancel the software environment, execute the following command.

$ module unload environmental_settings

For example, to discard the Gaussian environmental setting, use the following command.

$ module unload gaussian09-C.01

Setting Up the Session Environment

Editing the following files automatically sets up the session environment after logging in.

• When using sh: ~/.profile
• When using bash: ~/.bash_profile
• When using csh: ~/.cshrc

Example 1: To use ansys, gaussian, and conflex in your session through bash, add the following codes to ~/.bashrc.

eval `modulecmd bash load ansys14.5`
eval `modulecmd bash load gaussian09-C.01`
eval `modulecmd bash load conflex7`

Example 2: To use OpenMPI, Intel Compiler, gaussian, and conflex in your session through csh, add the following codes to ~/.cshrc.

eval `modulecmd tcsh unload intelmpi.intel`
eval `modulecmd tcsh load openmpi.intel`
eval `modulecmd tcsh load gaussian09-C.01`
eval `modulecmd tcsh load conflex7`

The following command displays the currently loaded modules.

$ module list

The following command displays the available modules.

$ module avail

To compile a FORTRAN program, execute the following command.

$ mpiifort source_file_name –o output_program_name

OpenMPI, MPICH2, MPICH1

To compile a C/C++ program, execute the following command.

$ mpicc source_file_name –o output_program_name

To compile a FORTRAN program, execute the following command.

$ mpif90 source_file_name –o output_program_name

$ mpif77 source_file_name –o output_program_name

Executing Jobs

The job management system, Torque, is used to manage jobs to be executed. Always use Torque to execute jobs.

Queue Configuration

/* * Computer Systems for the Next Generation Simulation Technology Education

• Wide-Area Coordinated Cluster System for Education and Research

Submitting Jobs

Create the Torque script and submit the job as follows using the qsub command.

$ qsub –q quque_name script_name

For example, enter the following to submit a job to rchq, a research job queue.

$ qsub -q rchq script_name

In the script, specify the number of processors per node to request as follows.

#PBS -l nodes=no_of_nodes:ppn=processors_per_node

Example: To request 1 node and 16 processors per node

#PBS -l nodes=1:ppn=16

Example: To request 4 nodes and 16 processors per node

#PBS -l nodes=4:ppn=16

To execute a job with the specified memory capacity, add the following codes to the script.

#PBS -l nodes=no_of_nodes:ppn=processors_per_node,mem=memory_per_job

Example: To request 1 node, 16 processors per node, and 16GB memory per job

#PBS -l nodes=1:ppn=16,mem=16gb

To execute a job with the specified calculation node, add the following codes to the script.

#PBS -l nodes=nodeA:ppn=processors_for_nodeA+nodeB:ppn= processors_for_nodeB，・・・

Example: To request csnd00 and csnd01 as the nodes and 16 processors per node

#PBS -l nodes=csnd00:ppn=16+csnd01:ppn=16

* From csnd00 to csnd27 are the calculation nodes (see Hardware Configuration under System Configuration).

* csnd00 and csnd01 are equipped with Tesla K20X.

To execute a job on a calculation node with GPGPU, add the following codes to the script.

#PBS -l nodes=1:GPU:ppn=1

To execute a job in a specified duration of time, add the following codes to the script.

#PBS -l walltime=hh:mm:ss

Example: To request a duration of 336 hours to execute a job

#PBS -l walltime=336:00:00

The major options of the qsub command are as follows.

CASTEP/DMol3 Job

There are two ways to run Materials Studio CASTEP/DMol3 using the University’s supercomputer:

(1) Submit the job from Materials Studio Visualiser to the supercomputer (only Materials Studio 2016 is supported).

(2) Transfer the input file to the supercomputer using Winscp etc. and submit the job using the qsub command.

This section explains about the method (2).　To submit the job in the method (2), the parameters to pass the job scheduler can be changed.　The following is an example using CASTEP.

1. Create an input file using Materials Studio Visualizer.

In the CASTEP Calculation window, click Files….

In the CASTEP Job Files window, click Save Files.

The input file is stored at:

specified_path\project_name_Files\Documents\folder_created_in_above_step

For example, when performing an energy calculation using acetanilide.xsd in CASTEP following the above steps, the folder is created with the name of acetanilide CASTEP Energy.

The above specified_path is usually C:\Users\account_name\Documents\Materials Studio Projects.

The folder name contains a blank character.　Delete the blank character or replace it with underscore (_).　The folder name must not contain Japanese characters.

2. Using file transfer software such as Winscp, transfer the created folder and the file it contains to the supercomputer.

3. Create a script as follows in the transferred folder and submit the job using the qsub command.

### sample

#!/bin/sh
#PBS -l nodes=1:ppn=8,mem=24gb,pmem=3gb,vmem=24gb,pvmem=3gb
#PBS -l walltime=24:00:00
#PBS -q rchq

MPI_PROCS=`wc -l $PBS_NODEFILE | awk '{print $1}'`

cd $PBS_O_WORKDIR

cp /common/accelrys/cdev0/MaterialsStudio8.0/etc/CASTEP/bin/RunCASTEP.sh .
perl -i -pe 's/\r//' *

./RunCASTEP.sh -np $MPI_PROCS acetanilide

* Specify the file name without an extension in the transferred folder as the third argument in RunCASTEP.sh.

* Specify a value of 8 or less in =ppn.

* The values for the duration of job execution and the permitted memory capacity can be changed as necessary.

* Specifications in the Gateway location, Queue, and Run in parallel on fields in the Job Control tab in the CASTEP Calculation window will be ignored in job execution from the command line. The settings specified in the script used with the qsub command will be used.

* The script contents vary depending on the computer and calculation modules to be used. See the following Example Scripts.

4. After the job is completed, transfer the result file to your client PC and view the results using Materials studio Visualizer.

Notes on Joint Research

There are eight Materials Studio licenses owned by the University for CASTEP and a further eight for Dmol3. 1One job with eight or less parallel executions can be conducted under a single license. These licenses are shared. Avoid exclusively occupying the licenses and consider other users.
