Acquisition of a Beowulf cluster for seismological research

该合同的资金为购买多节点计算机集群提供部分支持。有了这个新设备，普林斯顿大学的地球物理学家将研究地震如何影响当地的地壳应力场，并改变新地震事件的可能性。进一步的算法开发也将大大提高我们对地球内部结构成像的能力。这种改进将包括有限频率波前愈合的效果。将波衍射效应纳入更真实的地震层析图的数学理论是在普林斯顿开发的，但该小组迄今为止缺乏计算设备，无法在地质兴趣分辨率（100公里）上充分利用它。＊＊＊

0131152NoletFunds from this award provide partial support for purchase of a multi-node computer cluster. With this new facility, geophysicists at Princeton University will study how earthquakes influence local crustal stress fields and change the probability of new seismic events. Further algorithm development should also make significant improvements in our ability to image the interior structure of the Earth. Such improvements will incorporate the effects of finite frequency wavefront healing. Mathematical theories incorporating the effects of wave diffraction for more realistic seismic tomograms were developed at Princeton but this group has so far lacked the computational facilities to exploit it fully at resolutions of geological interest ( 100 km). ***
