In the present work we report on simulations recently carried out using the EUTERPE gyrokinetic code. The scaling of the code has been studied up to twenty thousand processing elements. Linear and non-linear simulations of Ion Temperature Gradient (ITG) instabilities have been carried out in screw-pinch geometry and the results are compared to those previously obtained using the TORB code finding a good agreement. The influence of a finite beta on the growth rates of instabilities and on the zonal flows in a screw-pinch has also been studied. The results are compared with previous ones.
