Jeff Layton, Cluster Monkey staff-writer, wrote an excellent article about the different technologies available and suitable for cluster-interconnects.
The article covers Ethernet-, Myrinet and Infiniband-technologies, as well as different approches to MPI like MPI/GAMMA, which circumvents all the kernel-level TCP/IP stuff and performs with latencies as low as a friggin’ 9.54 us from userspace to userspace!
I was impressed. Admit it, you’re too. Can’t wait to try that out – could be a project for this year’s Linuxbierwanderung, which will take place in Lithuania this year and which my wife an me will attend.
