Maple Example

You can copy and run the maple example on the cluster in your home directory like this:

$ cp -r /share/apps/samples/maple-serial
$ cd maple-serial
$ qsub maple-serial

This is a simple polynomial and the goal is to find the roots of the polynomial.

This explains how to write a simple Maple job and submit it to the HPC.

 

Open Maple and start a new project:

# Solve a simple polynomial equation

f(x):=(x^9-x^8+x^7-x^6+x^5-x^4+x^3-x^2+x^4+9*x^3-2.4^2+.5*x)/(x-1);
myroots:=solve(f(x)=148596);

# Save the results into a Maple input file for later post-processing.
save myroots, "myroots.mpl";

 

Save this file as findroots.mpl.

When this runs, it will save the output to the myroots.mpl file.

 

Now, you need to SSH into the cluster with your MST userID/password.

Once connected, you need to copy the findroots.mpl file from your local system to your home directory on the cluster.

For easy of use, we use Filezilla as the sftp client.  WinSCP will work as well.

Create a connection in Filezilla using: 

 

From here you can navigate to your Maple file location on your local system and see your home directly on the cluster.

 

 

You can build your folder structure on the cluster how you wish, just use something that is meaningful.

Once copied, you can return to you SSH connection and create your jobfile to run your findroots.mpl project.

Open vi to create your job file.

Since this example is simple, I gave it 1 node - 15 minutes wall time, i want it to email me when it does things -abe, etc.

#PBS -N mytestrun
#PBS -q @nic-cluster.mst.edu
#PBS -l nodes=1
#PBS -l walltime=00:15:00
#PBS -m abe
#PBS -M rlhaffer@mst.edu
#PBS -V
cd $PBS_O_WORKDIR
/share/apps/maple16/bin/maple -q findroots.mpl

 

**remember to save this as a meaningful .txt file

Back on your terminal window, do ---- qsub findroots.txt

 

This will queue the job and probably run pretty fast since it is just simple algebra.

When done, you should have an .o###### file and a .e###### file.

The .o###### is the output of you job submission.

The .e###### is the generated error file, if something went wrong with your job.

This is the result in the .o###### file.
