This paper proposes a scheme to realize a high performance communication facility using a commodity network. This scheme does not require any special hardware or hardware specific device drivers in order to adapt to many kinds of network interface cards. In this scheme, a reliable lightweight network protocol is handled on a data link layer called by a network device driver directly. An interrupt reaping technique is proposed to eliminate the hardware interrupt overhead when an application waits for a message. PM/Ethernet, an instance of the scheme, is implemented on Linux with minimal modification to the Linux kernel, and existing network device drivers are used without any modification. Using Pentium III 500 MHz PCs on Packet Engine's G-NIC II Gigabit Ethernet NIC, it achieves 77.5 MB/s bandwidth and 37.6 µsec round trip time latency compared to that of TCP/IP which achieves 46.7 MB/s bandwidth and 89.6 µsec round trip time latency. The NAS parallel benchmark IS results show that MPI on PM/Ethernet achieves 75% better performance than MPI on TCP/IP and 7.8 % slower than that of MPI on Myrinet PM.
