Spill Response Evaluation Using an Oil Spill Model
Numerical simulation was used to evaluate the effectiveness of an oil spill response plan developed by Western Canada Marine Response Corporation (WCMRC) for the southwest coast of Canada. The plan was part of the permitting process for a proposed terminal expansion that would result in an increase in tanker traffic. The purpose of this response evaluation was to point the way to the developmen…

Study on Consistency of Diagnostic Ratios of Different Oils
Using GC/MS analysis means, distribution of n-alkanes, PAHs, and biomarkers and consistency of diagnostic ratios of different kinds of oil were studied. The results indicate that: (1) Some diagnostic ratios of different oils are not obviously different and may even be consistent. These diagnostic ratios include two n-alkanes diagnostic ratios ((C19+C20)/(C19~C22) and CPI), four terpanes diag…

Hydrogen and methane storage in adsorbent materials for automotive applications
SUMMARY: A huge obstacle to replacing gasoline as the main energy carrier in automotive applications is the relatively low energy density of suitable replacements. Gaseous energy carriers must be stored at high pressure or very low temperature in order to obtain an energy density suitable for vehicular use. High pressure gas storage requires large, cylindrical containers that occupy large amou…

Recently, Michaud questions the validity of weighted-IPC metrics by arguing that they are inconsistent and that weighted speedup favors unfairness [4]. Instead, he advocates us…

Bitwise operations are an important component of modern day programming, and are used in a variety of applications such as databases. In this work, we propose a new and simple mechanism to implement bulk bitwise AND and OR operations in DRAM, which is faster and more efficient than existing mechanisms. Our mechanism exploits existing DRAM operation to perform a bitwise AND/OR of two DRAM rows c…

Many-Core vs. Many-Thread Machines: Stay Away From the Valley
We study the tradeoffs between Many-Core machines like Intel’s Larrabee and Many-Thread machines like Nvidia and AMD GPGPUs. We define a unified model describing a superposition of the two architectures, and use it to identify operation zones for which each machine is more suitable. Moreover, we identify an intermediate zone in which both machines deliver inferior performance. We study the sh…

gem5-gpu: A Heterogeneous CPU-GPU Simulator
gem5-gpu is a new simulator that models tightly integrated CPU-GPU systems. It builds on gem5, a modular full-system CPU simulator, and GPGPUSim, a detailed GPGPU simulator. gem5-gpu routes most memory accesses through Ruby, which is a highly configurable memory system in gem5. By doing this, it is able to simulate many system configurations, ranging from a system with coherent caches and a si…

Hardware Support for Safe Execution of Native Client Applications
Over the past few years, there has been vast growth in the area of the web browser as an applications platform. One example of this trend is Google’s Native Client (NaCl) platform, which is a software-fault isolation mechanism that allows the running of native x86 or ARM code on the browser. One of the security mechanisms employed by NaCl is that all branches must jump to the start of a valid…

Generalized MultiAmdahl: Optimization of Heterogeneous Multi-Accelerator SoC
Consider a workload comprising a consecutive sequence of program execution segments, where each segment can either be executed on general purpose processor or offloaded to a hardware accelerator. An analytical optimization framework based on MultiAmdhal framework and Lagrange multipliers, for selecting the optimal set of accelerators and for allocating resources among them under constrained are…

Optimization of Application-Specific Memories
Memory access times are the primary bottleneck for many applications today. This “memory wall” is due to the performance disparity between processor cores and main memory. To address the performance gap, we propose the use of custom memory subsystems tailored to the application rather than attempting to optimize the application for a fixed memory subsystem. Custom subsystems can take advant…

Flattened Butterly Topology for On-Chip Networks
With the trend towards increasing number of cores in a multicore processors, the on-chip network that connects the cores needs to scale efciently. In this work, we propose the use of high-radix networks in on-chip networks and describe how the attened buttery topology can be mapped to on-chip networks. By using high-radix routers to reduce the diameter of the network, the attened buttery o…
