Creating Commercial Parallel Statistical Software

描述（由申请人提供）：该项目将为市场创建一个大型版本的Stata统计软件系统，用于对称多处理器（SMP）计算机，其执行速度比任何其他版本的Stata都要快。这个新版本将建立在Stata/SE之上，Stata/SE是Stata统计软件当前的顶级版本。许多卫生研究人员定期进行计算密集的统计分析。尽管计算机已经变得非常快，但这些研究人员仍然受到运行分析所需时间的限制。到目前为止，这些研究人员还没有使用SMP计算机的现成可访问性，因为没有商业上现成的统计软件可以以并行方式执行其计算。在之前的第一阶段SBIR项目中，Stata Corporation演示了其在数据循环中并行统计计算的方法，可以将一些大型数据集统计分析的运行时间在双处理器计算机上减少近一半，在四处理器计算机上减少近四分之一。在这个项目中，Stata公司建议在Stata所有将受益的部分实施这种方法。

DESCRIPTION (provided by applicant): This project will create for market a large version of the Stata Statistical Software system for use on Symmetric Multiprocessor (SMP) computers that will execute more quickly than any other version of Stata. This new version will be built on top of Stata/SE, the current top-of-the-line version of Stata Statistical Software. Many health researchers regularly perform computationally intensive statistical analyses. Although computers have become very fast, these researchers are still constrained by the time it takes to run their analyses. The ready accessibility of SMP computers has thus far not been of use to these researchers because there is no commercial off-the-shelf statistical software that will perform its computations in a parallel fashion. In a previous Phase I SBIR project, Stata Corporation demonstrated that its method of parallelizing statistical computations in loops over the data can decrease run times of some statistical analyses on large datasets by almost half on a two-processor computer and to nearly a quarter on a quad-processor computer. In this project, Stata Corporation proposes to implement this methodology throughout all the parts of Stata that will benefit.
