9615751 Romanowicz This grant provides $65,000 as one-half support of the costs of acquiring new and upgraded computer equipment for the Geophysics computer laboratory at UC Berkeley, a facility shared by the Berkeley Seismographic Station (BSS). Specifically, the equipment and upgrades will include a dual CPU SUN Enterprise 3000 server, eight Sun Ultra 1 140 upgrades to eight existing SUN SLC's, one new SUN Ultra 1 140 workstation and one SUN Ultra 1 200E workstation. The addition of a new faculty member, Dr. Doug Drever, and the computationally intensive needs of other seismologists and geophysicists at Berkeley will benefit from the new capabilities afforded by this equipment which will include using software to create a parallel virtual machine (PVM) from multiple upgraded workstations. Specific projects that will utilize this equipment include modeling of regional crustal and upper mantle structure in the western U. S. through inversion of broadband waveform data collected from multiple digital seismographic networks including both permanent BSS and IRIS GSN stations and data from portable IRIS-PASSCAL instruments, studies of the nucleation and growth of earthquake ruptures and statistical analyses of the relationships between large aftershocks and mainshock fault slip, global mantle tomography based on models of the anelastic attenuation of seismic waves, numerical modeling of geodynamic processes and ab intio calculations of the properties of mantle minerals. ***

9615751 Romanowicz这笔赠款提供了65,000美元，作为对在加州大学伯克利分校的地​​球物理计算机实验室购买新的和升级的计算机设备的一半支持，UC Berkeley是伯克利地震站（BSS）共享的设施。 具体而言，设备和升级将包括双CPU Sun Enterprise 3000服务器，八个Sun Ultra 1 140升级到八个现有的Sun SLC，一个新的Sun Ultra 1 140工作站和一个Sun Ultra 1 200E工作站。增加了一名新教师Doug Drever博士，以及伯克利其他地震学家和地球物理学家的计算密集需求，将从该设备提供的新功能中受益，其中包括使用软件来创建来自多个升级工作站的并行虚拟机（PVM）。将利用该设备的特定项目包括对美国西部区域地壳和上地幔结构进行建模，这是通过从多个数字地震学网络收集的宽带波形数据的倒置，包括永久性BSS和IRIS GSN电台，以及从便携式IRIS-Passcal工具中的可移植iris-Passcal仪器的数据，对全球的核对和统计学的研究，统计学的研究，统计学分析，统计学分析，统计学分析，统计学上的相关性，涉及到统计学的关系。地幔断层扫描基于地震波的厌氧衰减模型，地球动力学过程的数值建模以及地幔矿物质性质的AB Intio计算。 ***
