SuperTech'sgoal is to master all aspects of high-performance computing(including parallel and distributed processing) so thatmodern hardware technology can be translated intoefficient, easy-to-use computing systems. Organized as across-section of LCS, SuperTech represents a cooperativeeffort designed to address the problems of multiscalecomputing.<p>To achieve our mission, we are studying machinearchitecture, language design, parallel-computing theory,numerical analysis, operating system design, andcomputational science. Facilities include a 128-nodeConnection Machine CM-5 parallel supercomputer, severalSilicon Graphics high-performance graphics workstations,and networks of workstations.<p>SuperTech is driven in part by the fact that today'scomputer architect can select from a range of technologyoptions, including cost, performance, reliability, andpower. The variety of options will grow even larger withinthe next decade with the introduction of gigabit networks,lightweight batteries, multichip modules, and opticalswitches. As a result, we will soon see a diverse set ofmultiscale computing environments including wirelesscomputers, high-performance PCs, multiprocessorworkstations, clusters of distributed workstations,local-area supercomputers, and massively parallelsupercomputers that cover a wide range of performanceparameters.<p>This vision of multiscale computing, unfortunately,conflicts with an even more powerful force: softwareinertia. Existing software systems threaten multiscalecomputing, since they sanction only a few, well-establishedcomputing environments. Each new environment will requiremassive custom programming to retrofit the standardsoftware in its attempts to unify multiscale computing asusers will surely demand through common languages,operating systems, network protocols, and applications.<p>We cope with these limitations via common architectural andsoftware mechanisms designed to unify the diversemultiscale computing environments and encourage nichemarkets to flourish. This task requires hardware andsoftware design, the formulation of theoreticalfoundations, and applications development.<p>SuperTech cooperates closely with <!WA6><A HREF="http://www.cm5.lcs.mit.edu/">Project SCOUT</a>, an LCS-ledconsortium designed to promote interaction between computerand computational scientists. SCOUT members includeinterdisciplinary scientists from MIT, <!WA7><A HREF="http://web.bu.edu/">Boston University</a>,and <!WA8><A HREF="http://www.harvard.edu/">Harvard</a>.
