Oak Ridge National Laboratory (ORNL) in Tennessee, a historically significant site for atomic energy research, has expanded its focus to include diverse scientific fields, supported by its cutting-edge supercomputing capabilities. The lab's current supercomputer, Summit, with a performance of 200 petaFLOPS, is soon to be surpassed by Frontier, the first exascale computer in the U.S., boasting 1.5 exaFLOPS. Frontier's significant power requirements make optimization crucial, and ORNL leverages Elastic's technology for system monitoring and performance enhancement. Using Elastic's data analytics and visualization tools, the lab has achieved substantial savings in cooling costs and improved data management, showcasing their expertise in handling massive data streams. Elastic's solutions help ORNL maintain the stability and efficiency of their supercomputers, allowing scientists to focus on innovative research across various domains, while ORNL offers insights into effective Elastic usage for high-performance computing applications.
