摘要： A system for allocation of one or more data structures used in a program across a number of processing units takes into account a memory access pattern of the data structure, and the amount of total memory available for duplication across the several processing units. Using these parameters duplication factors are determined for the one or more data structures such that the cost of remote communication is minimized when the data structures are duplicated according to the respective duplication factors while allowing parallel execution of the program.

摘要： A compilation system can compile a program to be executed using an event driven tasks (EDT) system that requires knowledge of dependencies between program statement instances, and generate the required dependencies efficiently when a tiling transformation is applied. To this end, the system may use pre-tiling dependencies and can derive post-tiling dependencies via an analysis of the tiling to be applied.

摘要： A compilation system using an energy model based on a set of generic and practical hardware and software parameters is presented. The model can represent the major trends in energy consumption spanning potential hardware configurations using only parameters available at compilation time. Experimental verification indicates that the model is nimble yet sufficiently precise, allowing efficient selection of one or more parameters of a target computing system so as to minimize power/energy consumption of a program while achieving other performance related goals. A voltage and/or frequency optimization and selection is presented which can determine an efficient dynamic hardware configuration schedule at compilation time. In various embodiments, the configuration schedule is chosen based on its predicted effect on energy consumption. A concurrency throttling technique based on the energy model can exploit the power-gating features exposed by the target computing system to increase the energy efficiency of programs.
摘要翻译：提出了一种使用基于一般和实用的硬件和软件参数的能量模型的编译系统。该模型可以使用仅在编译时可用的参数来代表跨越潜在硬件配置的能源消耗的主要趋势。实验验证表明，该模型灵活而精确，允许有效选择目标计算系统的一个或多个参数，以便最小化程序的功率/能量消耗，同时实现其他性能相关目标。提出了可以在编译时确定有效的动态硬件配置进度的电压和/或频率优化和选择。在各种实施例中，基于其对能量消耗的预测影响来选择配置计划。基于能量模型的并发节流技术可以利用目标计算系统暴露的功率门控特性来提高节目的能源效率。

摘要： A system for determining the physical path of an object can map several candidate paths to a suitable path space that can be explored using a convex optimization technique. The optimization technique may take advantage of the typical sparsity of the path space and can identify a likely physical path using a function of sensor observation as constraints. A track of an object can also be determined using a track model and a convex optimization technique.
