 US Department of Energy (DOE) computing facilities began deploying petasca
 le systems in 2008, DOE was already setting its sights on exascale. In tha
 t year, DARPA published a report on the feasibility of reaching exascale. 
 The report authors identified several key challenges in the pursuit of exa
 scale including power, memory, concurrency, and resiliency. That report in
 formed the DOE's computing strategy for reaching exascale. With the deploy
 ment of Oak Ridge National Laboratory's Frontier supercomputer, we have of
 ficially entered the exascale era. In this paper, we discuss Frontier's ar
 chitecture, how it addresses those challenges, and describe some early app
 lication results from Oak Ridge Leadership Computing Facility's Center of 
 Excellence and the Exascale Computing Project.\n\nTag: Exascale, Large Sca
