摘要

我们提出了一个多gpu代码的初步结果，通过使用广度优先搜索算法来探索大型图(数亿个顶点和数十亿条边)。GPU主机通过APEnet+连接，APEnet+是一个定制的互连网络，完全支持NVIDIA GPUDirect对等通信，即允许第三方设备通过PCI快速总线直接访问GPU内存的技术。

Breadth First Search on APEnet+

We present preliminary results of a multi-GPU code for exploring large graphs (hundreds of millions vertices and billions of edges) by using the Breadth First Search algorithm. The GPU hosts are connected by APEnet+, a custom interconnection network that has full support for NVIDIA GPUDirect peer-topeer communication, i.e. the technology allowing a third party device to directly access the GPU memory over the PCI express bus.
