Engineering Research Equipment Grant: Acquisition of Float- ing Point Array Processors/for Seismic Analysis Research

研究设备提供给哥伦比亚大学的地震工程项目。为了跟上与计算相关的地震分析研究的进展，HP-9000计算机系统需要两个模拟阵列处理器，包括8mb RAM， 1600bpi磁带，图形处理器和2mb附加内存，并补充其矢量化数学子程序包。阵列处理器在与HP-9000计算机系统集成时是独一无二的，该系统已安装在土木工程部。除了经济之外，该系统将提供比更大、更昂贵的大型计算机更高的性能选择，例如，解决大规模数值问题，包括复杂特征解和多维傅里叶变换，以及执行信号和图像处理操作，所有这些都是实时的。

Research equipment is provided to support Columbia University's earthquake engineering program. To keep abreast of advances in computing-related seismic analysis research, two Analogic Array Processors consisting of an 8 MB RAM, a 1600 bpi magnetic tape, graphics processor and 2 MB of additional memory for the HP-9000 computer system supplemented by its vectorized mathematical subroutine packages are required. Array processors are unique when integrated with the HP-9000 computer system, which has been installed in the Civil Engineering Department. Besides being economical, the system will provide an even higher performance alternative to larger and much more expensive mainframe computers in terms of, for example, solving large-scale numerical problems including those of complex eigen solutions and multi-dimensional Fourier transforms, and in terms of performing signal and image processing operations--all in real time.
