How to know that a particular JOB will = take how much memory and CPU

If your are managing calculations in = personal computers, Gaussian is a very annoying software. However, is = best for run in parallel. There are a table about memory space in the = Gaussian website about parameters to optimaze properly the calculation, = nevertheless, its terrible if you try to run in single machines

I = strongly recommend use jaguar: is better than gaussian and you donthave = to manage CPU and space memory.
