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 65,000 美元，作为为加州大学伯克利分校地球物理计算机实验室（伯克利地震站 (BSS) 共享的设施）购买新的和升级的计算机设备的费用的一半支持。 具体来说，设备和升级将包括一台双CPU SUN Enterprise 3000 服务器、八台Sun Ultra 1 140 升级至八台现有SUN SLC、一台新的SUN Ultra 1 140 工作站和一台SUN Ultra 1 200E 工作站。新教员 Doug Drever 博士的加入以及伯克利分校其他地震学家和地球物理学家的计算密集型需求将受益于该设备提供的新功能，其中包括使用软件创建并行虚拟机 (PVM)多个升级的工作站。将利用该设备的具体项目包括通过反演从多个数字地震网络（包括永久 BSS 和 IRIS GSN 站）以及便携式 IRIS-PASSCAL 仪器和研究中收集的宽带波形数据，对美国西部的区域地壳和上地幔结构进行建模地震破裂成核和扩展的研究以及大余震与主震断层滑移关系的统计分析、基于地震波滞弹性衰减模型的全球地幔层析成像、地震数值模拟地球动力学过程和地幔矿物特性的从头计算。 ***
