Mathematics, Numerics

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

[leonhard@euler04 ~]$ module load new maple/2016
[leonhard@euler04 ~]$ 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:

bsub [LSF options] "maple test.inp"

Here you need to replace [LSF options] with LSF parameters for the resource requirements of the job. Please find a documentation about the parameters of bsub 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.

[leonhard@euler09 ~]$ ls
test.inp
[leonhard@euler09 ~]$ cat test.inp
with(NumberTheory):
interface(rtablesize=50):
DataSeries([seq(IthMersenne(i),i=1..48)],labels=[seq(1..48)]);
[leonhard@euler09 ~]$ module load new maple/2016
[leonhard@euler09 ~]$ bsub -n 1 -W 0:05 -R "rusage[mem=50]" maple test.inp
Generic job.
Job <33884023> is submitted to queue <normal.4h>.
[leonhard@euler09 ~]$ bjobs
JOBID      USER       STAT  QUEUE      FROM_HOST   EXEC_HOST   JOB_NAME   SUBMIT_TIME
33884023   leonhard   PEND  normal.4h  euler09                 * test.inp Dec 12 15:11

JOBID      USER       STAT  QUEUE      FROM_HOST   EXEC_HOST   JOB_NAME   SUBMIT_TIME

[leonhard@euler09 ~]$ bjobs
No unfinished job found
[leonhard@euler09 ~]$ grep -m 2 48 lsf.o33884023 | tail -n1
                                [48    57885161]

You can find the resource usage summary for the job in the LSF log file.

License information

Maple license is centrally provided by the IT shop of ETH.

Notes

Currently, the status of the Maple 17 license is not clear. The license server returns an error message:

[leonhard@euler06 ~]$ module load maple/17
[leonhard@euler06 ~]$ maple
Maple initialization error, No such feature exists.
Feature:       Maple17
License path:  /cluster/apps/maple/17/x86_64/license/license.dat:
FLEXnet Licensing error:-5,412
For further information, refer to the FLEXnet Licensing documentation,
available at "www.acresso.com".
[leonhard@euler06 ~]$

We are trying to clarify this issue with the support from the IT shop.
