项目摘要

In this research, we designed and developed a network card for PC clusters using field programmable gate arrays (FPGA), and realized a PC cluster system with this card. This network card is a 32-bit PCI bus card and consists of one FPGA, two RAMs, and four connectors. The PCI interface, four communication ports, and a five-port switch are implemented in one FPGA, and the network configuration can be changed by reconfiguring the FPGA. The communication rate is recorded in one of the two RAMs, and the timing of events, such as communication start/end, are recorded in another RAM.We developed software, including a device driver for the network card, communication library, and visualization tools. The device driver is implemented as a kernel module for the Linux OS. The communication library provides basic communication functions, such as initialize, finalize, send, receive, broadcast, and barrier synchronization. In addition, a reconfiguration tool was developed, which reconfigures the FPGA in each PC of the cluster from a management PC.We used the card to construct a PC cluster system connected by a ring network. For system evaluation, measurement and comparison of communication performance were performed while changing the depth of the communication buffer by reconfiguring the FPGA. The communication rate and timing were measured and visualized at the execution of Jacobi method, using the card's communication log function.In conclusion, the test confirmed the basic system functions. We are currently expanding the system to a two-dimensional lattice-type network.

在本研究中，我们利用现场可编程门阵列（FPGA）设计开发了一种用于PC集群的网卡，并利用该卡实现了PC集群系统。该网卡是32位PCI总线卡，由1个FPGA、2个RAM和4个连接器组成。 PCI接口、四个通信端口和一个五端口交换机都在一块FPGA中实现，并且可以通过重新配置FPGA来改变网络配置。通信速率记录在两个RAM中的一个中，事件的时间（例如通信开始/结束）记录在另一个RAM中。我们开发了软件，包括网卡的设备驱动程序、通信库和可视化工具。设备驱动程序作为 Linux 操作系统的内核模块实现。通信库提供基本的通信功能，例如初始化、终结、发送、接收、广播和屏障同步。此外，还开发了一个重新配置工具，可以从管理PC上重新配置集群中每台PC中的FPGA。我们使用该卡构建了一个通过环网连接的PC集群系统。为了进行系统评估，通过重新配置 FPGA 来改变通信缓冲区的深度，同时进行通信性能的测量和比较。使用卡的通信日志功能，在执行雅可比方法时测量并可视化通信速率和时序。总之，测试确认了基本的系统功能。我们目前正在将该系统扩展到二维晶格型网络。
