In high performance computing, applications often require very accurate solutions while minimizing runtimes and power consumption. Improving the ratio of the number of logic gates implementing floating point arithmetic operations to the total number of logic gates enables greater efficiency, potentially with higher performance and lower power consumption. Software executing on the fixed hardware in Von-Neuman architectures faces limitations on improving this ratio, since processors require extensive supporting logic to fetch and decode instructions while employing arithmetic units with statically defined precision. This dissertation explores novel approaches to improve computing architectures for linear system applications not only by designing application-specific …

Mathematical and statistical modeling of biological systems is a desired goal for many years. Many biochemical models are often evaluated using a deterministic approach, which uses differential equations to describe the chemical interactions. However, such an approach is inaccurate for small species populations as it neglects the discrete representation of population values, presents the possibility of negative populations, and does not represent the stochastic nature of biochemical systems. The Stochastic Simulation Algorithm (SSA) developed by Gillespie is able to properly account for these inherent noise fluctuations. Due to the stochastic nature of the Monte Carlo simulations, large numbers of simulations …
