Construction of Designs and Codes using computers

我研究的长期目标是使用计算机来解决与组合对象的存在和计数相关的公开问题。这类研究的一个特点是，它通常需要大量的计算，相当于在几个月或几年内使用数百台计算机。自20世纪90年代中期S以来，典型的大学教学实验室中的计算机提供了最具成本效益的计算环境。当没有学生使用这些计算机时，例如在夜间，人们只能将它们用于研究目的。然而，这种幸运的情况正在改变。随着电脑价格的下降，越来越多的学生开始购买自己的笔记本电脑。大学正开始削减学生不需要的通用计算设施，并转向一种模式，即提供更少的计算机，但提供学生通常无法使用的更高端的机型，以补充他们的学习体验。对于研究人员来说，最终的结果是我们可以使用更少但更强大的计算机。这些高端计算机通常配备多核CPU，并配备强大的图形处理器。虽然有效使用多核CPU很容易，但有效使用图形处理器就不那么简单了。

The long term objective of my research is to use computers to solve open problems related to the existence and enumeration of combinatorial objects. One characteristic of this type of research is that it often requires a large amount of computing, something equivalent to using hundreds of computers over months or years. Since the mid 1990's, computers found in typical university teaching laboratories provide the most cost-effective computing environment. One can just use these computers for research purposes when no students are using them, such as during the overnight hours. However, this fortunate situation is changing. As the price of computer drops, more and more students are buying their own laptops. Universities are starting to cut back on general computing facilities that students do not need, and moving towards a model of providing fewer computers but with higher-end models that students normally do not have access to, in order to complement their learning experience. The net result, for the researchers, is that we have access to fewer but more powerful computers. These high end computers typically have multi-core CPU's, and have powerful graphics processors. While it is easy to effectively use the multi-core CPU's, using the graphics processors effectively is not as simple.
