Description

Maple is a symbolic and numeric computing environment, and is also a multi-paradigm programming language. Developed by Maplesoft, Maple also covers other aspects of technical computing, including visualization, data analysis, matrix computation, and connectivity. A toolbox, MapleSim, adds functionality for multidomain physical modeling and code generation

Interactive session

You can start an interactive Maple session on a login node by loading the maple module and starting Maple with the command maple

[sfux@eu-login-18 ~]$ module load maple/2019.1
[sfux@eu-login-18 ~]$ maple

Please note that interactive sessions should only be used for short testing or pre- and post-processing. Calculations that need more resources must be submitted to the batch system.

How to submit a job

You can submit a Maple job (test.inp) to the batch system with the follwoing command:

sbatch [Slurm options] --wrap="maple test.inp"

Here you need to replace [Slurm options] with Slurm parameters for the resource requirements of the job. Please find a documentation about the parameters of sbatch on the wiki page about the batch system.

Example

As an example for a Maple job, we are running a script that create a table with the exponents of the 48 known Mersenne prime numbers.

[sfux@eu-login-09-ng ~]$ ls
test.inp
[sfux@eu-login-09-ng ~]$ cat test.inp
with(NumberTheory):
interface(rtablesize=50):
DataSeries([seq(IthMersenne(i),i=1..48)],labels=[seq(1..48)]);
[sfux@eu-login-09-ng ~]$ module load new maple/2019.1
[sfux@eu-login-09-ng ~]$ bsub -n 1 -W 0:05 -R "rusage[mem=50]" maple test.inp
