摘要: 现有的许可链系统大多采取串行的事务执行方式,无法利用多核处理器的性能优势。在共识算法性能较高的许可链中,这种串行的事务执行方法将会成为性能瓶颈。为降低排序-执行-验证架构的许可链中事务执行的时间开销,文中提出了两种事务并发模型。首先,提出了基于地址表的并行执行模型,通过静态分析的方法将事务的读写集映 ...

摘要: 【目的】 为了解决传统单平台任务分配中的供需不平衡问题,跨平台在线匹配成为了一种新兴解决方案,它允许多个类似的平台建立合作关系,将无法完成的任务发送给其他平台,增加任务被接受的概率。然而,目前的跨平台在线匹配都只考虑了单轮的匹配过程,难以在多平台竞争中找到良好的决策结果。为了解决以上不足,研究了多轮 ...
