An Isotach Implementation for Myrinet

Author:Regehr, John, Department of Computer ScienceUniversity of Virginia

An isotach network provides strong guarantees about message delivery order. We show that an isotach network can be efficiently implemented entirely in software, on off-the-shelf hardware. Parts of this implementation could be performed much more efficiently in hardware - we are currently developing hardware components to do this. The all-software version then serves several purposes: to rapidly develop a working isotach system to use as a platform for development of higher level software, to find potential problems in the hardware design, and to pre-test software components of the system so that they won't have to be debugged at the same time as hardware.
