Dinosaur Footprint Fossils Discovered in Xinjiang

Recently, a Chinese-German science fieldwork investigation team, composed of staff from the Sino- German Paleontology and Geography Joint Lab and the Xinjiang Geological Work Station, announced that they discovered a batch of dinosaur footprint fossils in the dessert 20 kilometers to the east of Shanshan County in the Turpan Basin, Xinjiang Uyghur Autonomous Region. These fossils spread around an area of 100 square meters and scientists believed that these footprints were left behind by carnivore dinosaurs. This major discovery has been published in Global Geology, an English journal published by the North- East Asia Geology Center.     

基于自律分散系统在线技术的轨道电路监测系统优化

Implementation Study Tree Computation on of Dynamic Load Balancing Algorithm of Parallel Clusters of Heterogeneous Workstation

The rapid growth of interconnected high performance workstations has produced a new computing paradigm called clustered of workstations computing. In these systems load balance problem is a serious impediment to achieve good performance. The main concern of this paper is the implementation of dynamic load balancing algorithm, asynchronous Round Robin （ARR）, for balancing workload of parallel tree computation depth-first-search algorithm on Cluster of Heterogeneous Workstations （ COW ） Many algorithms in artificial intelligence and other areas of computer science are based on depth first search in implicitty defined trees. For these algorithms a load- balancing scheme is required, which is able to evenly distribute parts of an irregularly shaped tree over the workstations with minimal interprocessor communication and without prior knowledge of the tree＇s shape. For the （ ARR ） algorithm only minimal interprocessor communication is needed when necessary and it runs under the MPI （Message passing interface） that allows parallel execution on heterogeneous SUN cluster of workstation platform. The program code is written in C language and executed under UNIX operating system （Solaris version）.     

NOVELL系统在无盘教学网中的使用及管理
