The main system, named "Turing", consists of 42 computational nodes based on INTEL E5-2697v4 processors, for a total of about 1500 cores and some GPU nodes. It reachs an aggregate power of 60 Tflops. This cluster was installed on May 2017. Other small clusters are available, for additional 744 cores. The aggregate power available at CIRA is about 80 TFlops (including the GPUs ). At the and of 2018 the "Turing" system will be upgraded to 300TFlops also by means of new generation processors.</p><p>For what concerns the application software, many commercial codes ( eg .
