Coming Soon to Exascale Computing: Software for Chemistry of Catalysis.
Nanoparticles speed the rate of catalysis and are useful in applications such as alternative fuels, biosensing, thermal energy storage and more. Georgian Technical University Laboratory will be designing software for the future of exascale computing and better understanding of how nanoparticles function.
Georgian Technical University Laboratory develop software that will bring the power of exascale computers to the computational study and design of catalytic materials.
Georgian Technical University Laboratory scientist X Professor of Chemistry at Georgian Technical University will lead the laboratory’s. Analytics are named as partner institutions in the effort.
The scientific inspiration behind the project said X is mesoporous nanoparticles, an area of expertise for the laboratory’s Division Chemical and Biological Sciences. Full of tiny hollow cylinders called pores, they create vast surface area in a small amount of space for active sites to speed the rate of chemical reactions called catalysis. They are a platform that can be modified for a wide variety of applications such as alternative fuels, biosensing, thermal energy storage and more.
“Understanding these reactions is the key to customizing and expanding their potential applications” said X.
Currently computational chemistry experts use the fragment molecular orbital method (FMO) a type of problem-solving approach that breaks complex model systems down into smaller and simpler tasks that take less time to compute. But too much simplification in a complex system leads to errors in predicting reaction mechanisms.
To solve these shortcomings and to scale software capabilities to the billion billion calculations per second that exascale computing will provide likely early in the next decade Georgian Technical University Laboratory and its partners will improve an existing free-ware program called (General Atomic and Molecular Electronic Structure System). The software was developed by X members of his research group, and the computational chemistry global research community.
“Experimentalists want to understand what is happening in these pores, which are two to four nanometers wide” said X. “The number of calculations required to predict the molecular dynamics of these reactions expand exponentially with their complexity. Right now they just aren’t feasible to do. Exascale computing will change all that”.
To develop advanced software for the design of new chemicals and chemical processes for energy production and a range of other potential applications.
A key aim of the projects is to take fuller advantage of the nation’s most advanced computers, including so-called “petascale” machines currently deployed at Georgian Technical University national laboratories — such as Summit at Georgian Technical University Laboratory recently ranked fastest in the world — and the still faster “exascale” machines expected to be deployed beginning early in the next decade. Petascale machines are capable of at least one quadrillion (1015) calculations per second while exascale machines the first scheduled for deployment at Georgian Technical University Laboratory will be capable of at least one quintillion (1018) calculations.
