Using Recursion to Boost ATLAS's Performance
نویسندگان
چکیده
We investigate the performance benefits of a novel recursive formulation of Strassen’s algorithm over highly tuned matrix-multiply (MM) routines, such as the widely used ATLAS for high-performance systems. We combine Strassen’s recursion with high-tuned version of ATLAS MM and we present a family of recursive algorithms achieving up to 15% speed-up over ATLAS alone. We show experimental results for 7 different

متن کاملDesign of Maximum Power Point Tracking in Solar Array Systems Using Fuzzy Controllers
In recent year's renewable energy sources have become a useful alternative for the power generation. The power of photovoltaic is nonlinear function of its voltage and current. It is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (MPP) in various solar intensity. Fuzzy logic controller has advantage in handling non-linear system. Maximum power ...
متن کاملA New Topology for Z-Source Inverter Based on Switched-Inductor and Boost Z-Source Inverter
In this paper, a new topology for boost Z-source inverterbased on switched-inductor cell is proposed. The operating modes of the proposed inverter are analyzed and also a suitable control method to generate the trigger signals of the inverter is presented. Having a common earth between the input source and inverter and capability to generate a higher voltage gain by using lower amounts of the d...
متن کاملTRIOT: Faster tensor manipulation in C++11
Context: Multidimensional arrays are used by many different algorithms. As such, indexing and broadcasting complex operations over multidimensional arrays are ubiquitous tasks and can be performance limiting. Inquiry: Simultaneously indexing two ormoremultidimensional arrays with different shapes (e.g., copying data from one tensor to another larger, zero padded tensor in anticipation of a conv...
