Energy saving and environmental protection have always been the response to various fields. Nowadays, Formula One cars also set off energy-saving and environment-friendly reforms that will reduce the engine of the racing engine from V8 to V6 while ensuring the speed. At the same time, the Chinese saying goes, letting the horses run and the horses not grazing. For this classic game on the court, I am afraid that only big data, can become the best choice to solve it. F1 Circuit is probably one of the most classic scenarios for big data. The design, simulation, testing and construction of a fast-paced $ 200,000 Formula One racing car is done entirely in the computer.

A grid scheduling method based on hierarchical scheduling strategy and Dynamic Data replication Rai Jinhui Liangsong, the Task scheduling algorithm (YPP) and the Dynamic Data replication algorithm (E1/ZF) are proposed to solve the problem of how to efficiently perform task scheduling and data replication in grid, so as to reduce task execution time.　and construct a scheme to combine the two algorithms effectively. The scheme uses YPP algorithm to comprehensively consider the number of task waiting queue, the location of task demand data and the calculation capacity of the site, and adopt the hierarchical scheduling method of network structure, with the appropriate weight coefficient calculation ...
