Mathematica

Mathematica implements numeric and symbolic mathematics. This section illustrates how to submit a small Mathematica job to a PBS queue. This Mathematica example finds the three roots of a third-degree polynomial.

Prepare a Mathematica input file with an appropriate filename, here named myjob.in:

(* FILENAME:  myjob.in *)

(* Find roots of a polynomial. *)
p=x^3+3*x^2+3*x+1
Solve[p==0]
Quit

Prepare a job submission file with an appropriate filename, here named myjob.sub:

#!/bin/sh -l
# FILENAME:  myjob.sub

module load mathematica
cd $PBS_O_WORKDIR

math < myjob.in

Submit the job:


$ qsub -l nodes=1:ppn=20 myjob.sub 

View job status:

$ qstat -u myusername

View results in the file for all standard output, here named myjob.sub.omyjobid:
