1. A computer implemented method for presenting resource requirements in a grid computing system, the computer implemented method comprising: identifying processor capacity data and network capacity data for a plurality of grid nodes in the grid computing system for different periods of time, wherein identifying the network capacity data comprises: monitoring, by a processing unit, for the different periods of time, an amount of traffic on a number of links between nodes in the plurality of grid nodes in the grid computing system; and determining, by a processing unit, an availability of network capacity during the different periods of time based on the amount of traffic monitored to form the network capacity data; identifying, by a processing unit, processor resources and network resources needed by a grid project; generating, by a processing unit, a simulation of various phases of grid project execution in accordance with the processor capacity data and the network capacity data during the different periods of time based on the processor resources and network resources needed by the grid project; generating, by a processing unit, a statistical plot of processor capacity and network availability for a selected period of time within the different periods of time based on the simulation; and presenting, by a processing unit, a visualization of the statistical plot in a graphical user interface.
