In this paper we introduce the software development environment for Blue Gene, a massively parallel
system being developed at the IBM T. J. Watson Research Center. While the hardware is still in a
development phase, we are able to provide a complete system software stack consisting of compiler,
kernel, run-time libraries, and visualizer that can execute many user-level applications such as the Splash-2 benchmark suite. These applications execute in an instruction-level simulator that we have developed to validate our architecture and tools. We analyze the data obtained from these runs and make performance estimates that influence architectural decisions.
