loop_wrapper will help iterate commands and scripts over a range of dates, and parallelize the runs.
Typical usage:
The following will run my_script.py (could be .sh, .pl, .exe, etc...) at all specified dates, using 3 cpus on your machine:
[$] loop_wrapper --cpu 3 20150101 20150315 script.py {d:}
my_script.py 20150101
my_script.py 20150102
....
my_script.py 20150315
