This award facilitates scientific research using the large new computational resource named Blue Waters scheduled to be deployed at the University of Illinois at Urbana-Champaign. It provides travel funds to support technical coordination between the principal investigators at Purdue University, the Blue Waters project team and vendor technical team.Chip design faces a crisis. The 40 year process of transistor downscaling has led to atomic-scale features, making devices subject to unavoidable manufacturing irregularities at the atomic scale and to heat densities comparable to a nuclear reactor. A new approach to design that embraces the atomistic, quantum mechanical nature of the constituent materials is necessary to develop more powerful yet low energy devices.Electronic device engineering and material science must meet at the atomic scale to design new switching concepts. This demands the solution of quantum non-equilibrium statistical mechanics in systems in excess of 100 million complex degrees of freedom. Computations of this magnitude have been impossible, due to the lack of sufficiently powerful computers. Petascale computing creates an opportunity to pursue a multi-scale design approach that fuses nano scale (atomic) to the macro scale (wire), which will make possible new kinds of device designs that were previously unimaginable. The team is developing a general-purpose simulation engine. It will model electron transport in realistically extended devices using fully quantum mechanical (QM) models in an atomistic material description containing millions of atoms. Designers will be able to directly address questions of quantization and spin, tunneling, phonon interactions, and heat generation.

该奖项利用计划在Urbana-Champaign伊利诺伊大学部署的名为Blue Waters的大型新计算资源来促进科学研究。它提供了旅行资金，以支持普渡大学，蓝色水域项目团队和供应商技术团队的主要研究人员之间的技术协调。ChipDesign面临危机。晶体管降尺度的40年过程导致了原子尺度的特征，使设备在原子量表处受到不可避免的制造不规则性，并加热与核反应堆相当的密度。一种新的设计方法，该方法包含组成材料的原子，量子机械性质对于开发更强大而低的能量设备是必要的。电子设备工程和材料科学必须在原子尺度上满足以设计新的开关概念。这需要解决量子非平衡统计力学的解决方案，以超过1亿个复数自由度。由于缺乏足够强大的计算机，因此不可能进行如此大小的计算。 Petascale Computing创造了一个机会，可以采用多尺度的设计方法，将纳米量表（原子）融合到宏观尺度（WIRE），这将使以前难以想象的新型设备设计可能。该团队正在开发通用模拟引擎。它将使用完全量子机械（QM）模型在包含数百万个原子的原子材料描述中使用全量子机械（QM）模型对电子传输进行建模。设计师将能够直接解决量化和旋转，隧道，声子相互作用和热量产生问题。
