Multiple jobs reading from same file
I have a sequence of tasks that I routinely run and I'm trying to parallelize certain portions of the sequence. Specifically, there are 3 tasks which all read from the same file, each performing different operations and writing to their own seperate file. I was wondering if I could execute these three steps at the same time.

Side note: I didn't write the code for these steps, so I can't just wrap them all up into one or anything like that.
