With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

This article will explain why thread based programming is not the best way to implement application parallelism in a multi-core era. Moore's Law (Moore 1965 predicts that the number of components per integrated circuit doubles every 18-24 months) is still applicable, and its applicability is expected to continue into 2015-2020 years. Before 2005, the CPU clock rate also increased synchronously, which was enough to improve the performance of all applications executing on those CPUs. Http://www.aliyun.co ...
