Further Information
The Hybrid Technology MultiThreaded (HTMT) project is an attempt to design a machine with radically new hardware technologies that will scale to a petaflop by the 2004 time frame. These technologies range from multi-hundred GHz CPUs built from superconductive RSFQ devices through active optical networks and 3D holographic memories to Processing-In-Memory (PIM) for active memories. The resulting architecture resembles a three level hierarchy of networks of processing nodes of different technologies and functionality. All this new technology, however, has a huge and unknown effect on software execution models for applications. This paper discusses several potential HTMT models and how they can be prototyped and demonstrated using a combination of multithreaded Java and LAN-connected workstations.
