It is for the first time that quantum simulation for high-energy physics (HEP) is studied in the U.S. decadal particle-physics community planning, and in fact until recently, this was not considered a mainstream topic in the community. This fact speaks of a remarkable rate of growth of this subfield over the past few years, stimulated by the impressive advancements in quantum information sciences (QIS) and associated technologies over the past decade, and the significant investment in this area by the government and private sectors in the U.S. and other countries. High-energy physicists have quickly identified problems of importance to our understanding of nature at the most fundamental level, from tiniest distances to cosmological extents, that are intractable with classical computers but may benefit from quantum advantage. They have initiated, and continue to carry out, a vigorous program in theory, algorithm, and hardware co-design for simulations of relevance to the HEP mission. This Roadmap is an attempt to bring this exciting and yet challenging area of research to the spotlight, and to elaborate on what the promises, requirements, challenges, and potential solutions are over the next decade and beyond.

Southern Biomedical engineering Conference

作者： R. Machiraju R. Vickery Department of Computer Science NSF Engineering Research Center for Computational Field Simulation MS USA

Much information in an image is concentrated in a few regions. These are dominated by structures characterized by discontinuities in color intensity. We present a wavelet based image analysis algorithm that identifies features that persist across the scales of the wavelet decomposition. This is achieved through the notion of sub-band combining which we introduce here. We first decompose the image into scales using the wavelet transform. Then, for each pixel, the combining process computes a function that collects all the information available at the sub-band (detail) scales. The result is a mask image indicating the significance of every point. Additional processing and image enhancement can now concentrate their efforts in regions where the masks show high values. Medical images, which are band-limited and contain no illumination artifacts, are especially suited to take advantage of sub-band combining. We show how our method can be employed to remove noise, enhance, and smooth features in images from MRI and mammography. Also, we allude to the use of this method to the creation of scale maps for level-of-detail computations.

Annual Symposium on simulation

作者： A. Saha Department of Electrical and Computer Engineering and NSF/ERC for Computational Field Simulations Mississippi State University MS USA

A time-driven, flit-based, wormhole-routed, parallel processor network simulator has been designed in C with a user-friendly graphical user interface (GUI). To accommodate the unique requirements of real-time networks, the simulator is based on prioritized queues supporting various resource allocation policies. In the simulator, special care is taken to prevent various possible kinds of overlaps (in time) and deadlocks. As a consequence of real-time systems, all messages are associated with priorities and every virtual channel is associated with the priority of the message it stores. The simulator contains a simple test for the convergence of the average latency, and the throughput is always monitored to verify that it converges to the applied load. A candidate network function is accurately defined and this characterization is detailed enough to be simulated. The simulator is used to evaluate a set of communication characteristics that are deemed desirable for real-time parallel processors with respect to performance.< >

A candidate network function is accurately defined for real-time parallel computers. A concise, time-driven, flit-based, priority-driven, wormhole-routed, network simulator has been designed. Experimentation is performed by monitoring the latency and the throughput with variations in different network parameters. Initially the destination address, message length and message priority are generated randomly with a uniform distribution. Then, various non-uniformities are introduced to mimic realistic applications. Results are plotted and analyzed. © 1995 IEEE.

Frontiers of Massively Parallel Computation

作者： P.L. Vaughan A. Skjellum D.S. Reese Fei-Chen Cheng NSF Engineering Research Center for Computational Field Simulation Mississippi State University MS USA Department of Computer Science Mississippi State University MS USA

This paper presents a new kind of portability system, Unify, which modifies the PVM message passing system to provide (currently a subset of) the message Passing Interface (MPI) standard notation for message passing. Unify is designed to reduce the effort of learning MPI, while providing a sensible means to make use of MPI libraries and MPI calls (while applications continue to run in the PVM environment). We are convinced that this strategy will reduce the costs of porting completely to MPI, while providing a gradual environment within which to evolve. Furthermore, it will permit immediate use of MPI-based parallel libraries in applications, even for those applications that continue to use PVM for message passing. We describe several paradigms for supporting MPI and PVM message passing notations in a single environment, and note related work on MPI and PVM implementations. We show the design options that existed within our chosen paradigm (which is an MPI interface added to the base PVM system) and why we chose that particular approach. We indicate the total evolution path of porting a PVM application to MPI with the help of porting libraries. Finally, we indicate our current directions and planned future work.< >

International Workshop on Rapid System Prototyping (RSP)

作者： A. Saha R. Krishnamurthy NSF/ERC for Computational Field Simulation and Department of Electrical and Computer Engineering Mississippi State University MS USA

field programmable gate arrays (FPGAs) provide an innovative and flexible platform to implement and evaluate digital signal processing (DSP) applications. A CAD design methodology which is used to implement DSP algorithms is presented. An introduction is given to the various issues involved in the multi-chip partitioning of large DSP implementations, and approaches towards efficient auto-partitioners are also discussed in detail. The design and implementation of an 8-point 1D discrete cosine transform (DCT) and its inverse (IDCT) on a processor with FPGAs is presented in this paper, as an illustrative example of a typical DSP algorithm. The processor uses 16-bit precision, is implemented on six Xilinx 4000 type FPGAs and operates at 40 MHz.< >

The design of fast and efficient multipliers is imperative, because of its various applications in many areas of science and engineering. In the light of VLSI technology, it is important for computer hardware designers to be aware of the choices available to them, in selecting an efficient algorithm for their application. High speed cellular-array multipliers have been the logical and affordable improvement compared to the serial-parallel designs. The authors present a detailed discussion on the development of these multiplier algorithms and their FPGA implementations. The various issues involved in the design process are highlighted. The cost-performance comparison of the various cellular array multipliers and a discussion on the design methodology is also presented.< >
