Jython/Example

As an example for running a Jython job, we are printing out the mathematical constants $\Pi<math> and <math>e$. For this, we are using the following Jython script:

[leonhard@euler06 ~]$ ls
test.py
[leonhard@euler06 ~]$ cat test.py 
import math

print "Pi = %r" % math.pi
print "e = %r" % math.e

First you need to load the required modules for Jython:

[leonhard@euler06 ~]$ module load gcc/4.8.2 python/2.7.6 java/1.8.0_31 jython/2.7.0

then you can submit the job

[leonhard@euler06 ~]$ bsub -n 1 -W 0:05 -R "rusage[mem=128]" "jython test.py"
Generic job.
Job <33655748> is submitted to queue <normal.4h>.
[leonhard@euler06 ~]$ bjobs

No unfinished job found
[leonhard@euler06 ~]$ grep -A1 "Pi =" lsf.o33655748 
Pi = 3.141592653589793
e = 2.718281828459045

The resource usage summary of the job can also be found in the LSF log file.
