The fastest, most efficient computers on the planet, announced last week by the U.S. Department of Energy and IBM, integrate technology developed by University of Alberta computing scientists.

The two supercomputers are made up of 4,000 nodes each, in a room about the size of a basketball court. The first, Summit, housed at the Oak Ridge National Laboratory, was announced earlier this month. The second project, Sierra, arriving later this year, will be housed at the Lawrence Livermore National Laboratory in the United States.

The U of A team, comprising professor Nelson Amaral and graduate students Artem Chikin and Taylor Lloyd, provided technology used in the machine’s compiler—the program that translates what a programmer writes into machine code.

The U of A technology consists of a program analysis that predicts and allo...
