Both in a way, and from your computer. You need to give the job the same resources as it would require if running the tool directly. Galaxy is what sits on top, to organize you files and to offer up diverse tools from many open-source developers that will work together all in the same place.
I added a few tags that link to administration topics. The Docker version of Galaxy is probably the easiest to get running locally but you can decide. More could be going on, maybe the tool dependency configuration has a problem, and this is just not a resource limit problem.
