APEnet+：用于千万亿次规模商品集群的高带宽3D环面直接网络
APEnet+: high bandwidth 3D torus direct network for petaflops scale commodity clusters
摘要：
我们在此介绍的APElink+板是一款PCIe互连适配器，具有最新的线速和接口技术，以及对RDMA编程模型和GPU联网实验加速的硬件支持;该设计使我们能够构建低延迟、高带宽的PC集群，即APEnet+网络，这是我们新一代经济高效、可扩展数万倍的集群网络架构。一些测试结果和一个完整的测试平台的数据传输特性，基于商业开发卡安装Altera FPGA，提供。
英文摘要：
We describe herein the APElink+ board, a PCIe interconnect adapter featuring the latest advances in wire speed and interface technology plus hardware support for a RDMA programming model and experimental acceleration of GPU networking; this design allows us to build a low latency, high bandwidth PC cluster, the APEnet+ network, the new generation of our cost-effective, tens-of-thousands-scalable cluster network architecture. Some test results and characterization of data transmission of a complete testbench, based on a commercial development card mounting an Altera FPGA, are provided.
