Sriram Krishnamoorthy, a Pacific Northwest National Laboratory scientist, has been awarded $2.5 million for advanced computing research by the Department of Energy's Early Career Research Program.
He's one of 61 researchers, all within 10 years of earning their doctorates, to win the research grants this year.
Krishnamoorthy will spend the grant over five years to study the next step in supercomputer evolution -- the "exascale" computer, according to a PNNL press release.
Top supercomputers currently work at the "petascale" level, performing in one hour what would take a typical laptop more than 20 years to do. Exascale computing seeks to solve problems that are about 1,000 times bigger than what the top computers can do today.
That magnitude requires supercomputers to perform different parts of calculations simultaneously and then put all the pieces back together on the fly. The complexity increases the chances for problems that lead to crashes.
Krishnamoorthy has improved how supercomputers handle errors that could make them crash, narrowing the amount of work that a supercomputer has to repeat after a crash.
This can greatly improve the speed of science on supercomputers.
He will use the financial support from DOE to delve deeper into how parallel computing solves problems and make sure that the different pieces of the full calculation work as efficiently as possible.
