Abstract
The PVM development team continues to do distributed virtual machine research. Today that research revolves around the PVM project follow-on called Harness. Every three years the team chooses a new direction to explore. This year marks the beginning of a new cycle and this talk will describe the new directions and software that the PVM/Harness research team will developing over the next few years.
The first direction involves the use of Harness technology in a DOE project to develop a scalable Linux OS suited to petascale computers. Harness distributed control will be leveraged to increase the fault tolerance of such an OS. The second direction involves the use of the Harness runtime environment in the new Open MPI software project. Open MPI is an integration of several previous MPI implementations, including LAM-MPI, the LA-MPI package, and the Fault Tolerant MPI from the Harness project. The third research direction is called the ”Harness Workbench” and will investigate the creation of a unified and adaptive application development environment across diverse computing platforms. This research effort will leverage the dynamic plug-in technology developed in our Harness research. Each of these three research efforts will be described in detail.
Finally the talk will describe the latest news on DOE’s National Leadership Computing Facility, which will house a 100 TF Cray system at ORNL, and an IBM Blue Gene system at Argonne National Lab. We will describe the scientific missions of this facility and the new concept of ”computational end stations” being pioneered by the Facility.
