3.5.1 (2023/02/01)

## How to use HΦ on the ISSP supercomputer

• The directory where HPhi is installed.

/home/issp/materiapps/intel/hphi/

• The directory where the execution file of HPhi is installed.

/home/issp/materiapps/intel/hphi/hphi-3.5.1-1/bin/

(*) The build option can be checked by typing the following command:

$less /home/issp/materiapps/intel/hphi/hphi-3.5.1-1.log • The directory where sample scripts and input files are stored. /home/issp/materiapps/intel/hphi/hphi-3.5.1-1/samples/ • How to run HΦ (ex. calculation of the ground state energy on the Heisenberg chain by Lanczos method) 1. Preparing the computing environments $ source /home/issp/materiapps/intel/hphi/hphivars.sh
This will pass the PATH to the binary files of the latest version of HPhi. It also stores the path to the HPhi installation directory in the environment variable HPHI_ROOT. You can also use HPhi at the specific version. For example, if you want to use the version 3.5.1, please type as
$source /home/issp/materiapps/intel/hphi/hphivars-3.5.1-1.sh 2. Preparing input files $ cp -r $HPHI_ROOT/samples ~/HPhi-samples 3. Submitting job $ cd ~/HPhi-samples/old/CG/Heisenberg
$cp /home/issp/materiapps/intel/hphi/sample_jobscript/HPhi_standard.sh .$ sbatch HPhi_standard.sh
A sample script is available in /home/issp/materiapps/intel/hphi/sample_jobscript/. Copy the script to the current folder and submit the job. The sample scripts are HPhi_expert.sh for expert mode and HPhi_standard.sh for standard mode.

## Measurement of the number of times used

• We measure the number of uses of PASUMS software on the ISSP supercomputer. This becomes an important indicator for evaluating the significance of the project, and we appreciate your cooperation. We can also count the number of users who use versions of the software that are not pre-installed, so we would appreciate your cooperation in counting the number of users to help us understand how the software is being used (for details, please click here). If you do not wish to measure utilization when using pre-installed software, please select HPhi_nocount as the executable file.
