我们在KEKB e/sup +/e/sup -/对撞机上为Belle实验设计了一个无开关事件构建农场，作为现有事件构建器和在线农场系统的替代。在新系统中，pc机直接与多个点对点Fast和千兆以太网互连，分两步构建检测器数据并执行分布式事件处理。我们建立了一个测试系统，并使用真实的原型软件验证了事件构建性能满足我们的新要求。我们计划在2001年夏季停工期间安装该系统。
We designed a switchless event building farm for the Belle experiment at the KEKB e/sup +/e/sup -/ collider, as a replacement of the existing event builder and the online farm systems. In the new system, PCs are directly interconnected with multiple point-to-point Fast and Gigabit Ethernet, to build the detector data in two steps and to perform distributed event processing. We set up a test system and confirmed the event building performance meets our new requirements using realistic prototype software. We plan to install the system during the summer shutdown time of 2001.
