The non-local effects of turbulence can affect the transport especially in devices when the ration of ion gyroradius to plasma size ({rho}{sub i}*) is large. We show how the local linear and nonlinear ITG flux-tube results are modified when the simulations are done with finite {rho}{sub i}* in a global code.
