Search for lightweight alloying solutions earns team a Gordon Bell finalist nomination

DOE/Oak Ridge National Laboratory

A University of Michigan team used the 200-petaflop IBM AC922 Summit supercomputer to perform a simulation of a 10,000-atom magnesium dislocation system, a feat that could allow scientists to understand which alloying materials to add to improve magnesium alloys. By simulating a system tenfold larger than was possible with previous codes and 20 times faster, the team achieved a 200-fold speedup, running at 46 petaflops and earning an ACM Gordon Bell Prize finalist nomination.

Gordon Bell finalist team tackles transistors with new programming paradigm

DOE/Oak Ridge National Laboratory

A team at ETH Zurich performed a 10,000-atom simulation of a 2D slice of a transistor on the IBM AC922 Summit supercomputer and developed a map of where heat is produced in a single transistor. Using a new data-centric version of the OMEN nanodevice simulator, the team reached a sustained performance of 85.45 petaflops and earned a 2019 Association for Computing Machinery Gordon Bell Prize finalist nomination.

Chromosome Connectors Take Center Stage for ORNL Scientists Studying Poplar

DOE/Oak Ridge National Laboratory

A team at the US Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) mapped the locations of centromeres in the Populus trichocarpa (poplar) tree for the first time. A subsequent analysis on the Titan supercomputer showed that the sequence of DNA at the centromere and the sequence of a protein this DNA wraps around show similar occurrence patterns and may have evolved together.
