If you are using Linux (or Cygwin under Windows), I would suggest making either a simple loop in a bash script, or just enter all scripts explicitly. So, if you have the following scripts to run "script1.py", "script2.py", and "script3.py", you can either do
#!/bin/bash
for script in script*.py ; do
mpiexec ... atkpython $script > $script.log
done
or
#!/bin/bash
mpiexec ... atkpython script1.py > script1.log
mpiexec ... atkpython script2.py > script2.log
mpiexec ... atkpython script3.py > script3.log
NOTE that you should NOT use "&" to put the job in the background
The first option is better if you have many scripts as you don't have to write the filenames out explicitly.
Of course you have to fix the path etc of atkpython and add the relevant options for mpiexec. The scripts above should be saved in a file, like "run.sh" which should be given executable flags (chmod u+x run.sh). The you run the script as "./run.sh".
