Jack Dongarra, distinguished professor of computer science at UT is designing software that will be critical in making the next generation of supercomputers operational. For decades, supercomputers have been tackling the world’s most pressing challenges, from sequencing the human genome to predicting climate changes. But their power is limited and thus, so is our knowledge.
The way the power of supercomputers is measured is about to change. Since 1993, Jack Dongarra, distinguished professor of computer science at UT has led the ranking of the world’s top 500 supercomputers. The much-celebrated bi-annual TOP500 list is compiled using Dongarra’s benchmark system, called Linpack. But Dongarra says Linpack hasn’t kept pace with supercomputing needs and must be updated.
