# Strange output using qsub

I wrote a Sage code and it works fine on my notebook: nohup < QE.sage > QE.txt & the output file QE.txt looks OK. When I try to use the same code on a cluster using qsub -q test.q QE.sh then the output is

```

here QE.sh is as follows

```
#!/bin/sh
#$ -N QE.sage
module load sage
sage < QE.sage
```

Also if I use @parallel() on my notebook, then it works as expected:

```
@parallel(ncpus=2)
def szamol(a,b):
w=QEllCur([a,b,1])
if w==-1:
return "bad input"
else:
return w
W=list(szamol([(a,b) for a in range(-2,3) for b in range(-2,3)]))
for X, Y in sorted(W): print X, Y
```

The CPU time is about 2 sec on my notebook using 2 cores on the cluster using less than 12 cores it prints the first pair and that is it after running (not waiting in the que) more than 2 hours.

My questions are:

how to get the same output using my code on a (linux) cluster as using it on my (linux) notebook?

how to use @parallel() on a cluster?
