scientists, engineers, and students, jHepWork is a free open source data analysis framework that uses open source libraries to create a data analysis environment and provides a rich user interface to compete with those charged software. It is mainly for the scientific calculation of the two-and three-dimensional mapping, and contains the implementation of Java-based mathematical science library, random numbers, and other data mining algorithms. jHepWork is based on a high-level programming lang

is to be centralized and open source. I call it a "shared data layer and protocol layer". No one can control any part of the system, and these parts are open to all individuals and businesses. In Bitcoin, for example, a blockchain is a shared data layer, and the Bitcoin protocol is a centralized protocol that is part of the shared protocol layer.In this diagram, the more each layer is thinner, and the shared data layer and protocol layer occupy 80% of the total stack structure.

Compared to deferred lighting, this technique is not very popular due to the high memory size and bandwidth requirements. Especially on the 7th generation mainframe, the graphics memory size and bandwidth are limited and often bottlenecks.
