Description

From http://magma.maths.usyd.edu.au/magma/: "Magma is a large, well-supported software package designed for computations in algebra, number theory, algebraic geometry and algebraic combinatorics. It provides a mathematically rigorous environment for defining and working with structures such as groups, rings, fields, modules, algebras, schemes, curves, graphs, designs, codes and many others. Magma also supports a number of databases designed to aid computational research in those areas of mathematics which are algebraic in nature. "

• Version 2.25 (CPU version), installed in /apps/gb/Magma-AU/2.25

To use this version of magma, please first load the module with

module load Magma-AU/2.25

• Version 2.27-1-AVX (CPU version), installed in /apps/gb/Magma-AU/2.27-1-AVX

To use this version of magma, please first load the module with

module load Magma-AU/2.27-1-AVX

• Version 2.27-1-AVX2 (CPU version), installed in /apps/gb/Magma-AU/2.27-1-AVX2

To use this version of magma, please first load the module with

module load Magma-AU/2.27-1-AVX2

Use the --constraint Slurm header with the value EDR to ensure that your job lands on a node that supports AVX2.

• Version 2.27-1-AVX2-CUDA-10 (GPU version), installed in /apps/gb/Magma-AU/2.27-1-AVX2-CUDA-10

To use this version of magma, please first load the module with

module load Magma-AU/2.27-1-AVX2-CUDA-10

Use the --constraint Slurm header with the value EDR to ensure that your job lands on a node that supports AVX2.

When running Magma, please request the node feature magma, as only nodes with this feature are included in our Magma license file. To do that, please add the Slurm option --constraint=magma, as in the sample job submission script below.

Example of how to run magma in a batch job

1. Create a magma script. In the example below this script is called test.txt and its content is

print 3+5;

2. Create a job submission script, called sub.sh in the example here, with the sample content

#!/bin/bash
#SBATCH --job-name=testmagma         
#SBATCH --partition=batch           
#SBATCH --ntasks=1                   
#SBATCH --nodes=1
#SBATCH --mem=5gb                     
#SBATCH --time=12:00:00              
#SBATCH --output=%x.%j.out    
#SBATCH --error=%x.%j.err    
#SBATCH --constraint=magma,EDR    #request the node features magma & EDR


cd $SLURM_SUBMIT_DIR

module load Magma-AU/2.27-1-AVX2

magma test.txt > output_${SLURM_JOB_ID}.log

where test.txt needs to be replaced by the name of your magma program. Other parameters of the job, such as the maximum wall clock time, maximum memory, and the job name need to be modified appropriately as well. In this example, the standard output of the magma command will be saved into a file called "output_${SLURM_JOB_ID}.log", where ${SLURM_JOB_ID} will automatically be replaced by the jobid number.

3. Submit the job to the queue with

sbatch sub.sh
