		| Abstract: | 
		High performance computing numerical simulations are today one of the more effective instruments to implement and study
 new theoretical models, and they are mandatory during the preparatory phase and operational phase of any scientific experiment. 
 New challenges in Cosmology and Astrophysics will
 require a large number of new extremely  computationally intensive  simulations to investigate physical  processes at different scales.
 Moreover, the  size and complexity of the new generation of observational facilities also implies a new generation of high performance data reduction and analysis tools pushing toward the use of Exascale computing capabilities.
  Exascale supercomputers cannot be produced today.  We  discuss the major technological challenges in the design, development and
  use of such computing capabilities and we will report on the progresses that  has been made in the last years in Europe, in particular in the framework of the  ExaNeSt European funded project. We also discuss the impact of these new computing resources on the numerical codes in Astronomy and Astrophysics. |
