Parallel start of the Excel macro from UiPath

Hello.
I need help. I have a virtual server with 5 processors. You need to run 5 Excel macros for complex table calculations. Question: how best to start the robot UiPath-script, which runs these macros? There is an option to create multiple accounts on the server and from each run the robot. Either from the same account run the UiPath script in parallel, if technically allowed.
