Title:		MASSIVELY PARALLEL SYSTEMS AND GLOBAL OPTIMISATION

Speaker:	DR. NARENDRA KARMARKAR
 		Laboratory for Computational Mathematics


ABSTRACT:

We will briefly describe recent breakthrough in design of massively parallel 
systems based on insights derived from global optimization problems having 
multiple global optima. These designs include:

-  Physical design of the projective geometry machine using massively
    parallel quantum tunneling, which can totally overcome obstacles of
    latency and bandwidth faced by contemporary designs. The new design can
    broaden applicability of massive multi-threading to large and very
    general classes of computational problems, and can be implemented using
    already known fabrication techniques.

-  Design of multi-ported, low latency, secondary storage based on
    magneto-optics, implementing shared memory directly at physical level,
    providing a highly valuable feature for data bases and transactional
    memory.

-  Design of new high bandwidth switches required for next generation
    internet infrastructure.

-  Design of novel robots with large number of "electro-magnetic
    fingers" for placing atoms based on complex and sparse patterns of
    multiple global minima that are more general than regular periodic
    patterns achieved before using interference lithography.

-  Design of control systems whose stability analysis requires
    liapunov-like functions with multiple basins of attraction.

-  Design of phased-array radars in tera-hertz range.

-  Computational calibration of parameters occurring in empirical
    force fields, whose values may be difficult to measure experimentally
    but can be reverse engineered from known structure of folded proteins.

This work involves integration of ideas, concepts and processes from many 
fields:

-  Math (Optimization theory, Discrete subgroups of lie groups)
-  CS (Parallel Architectures)
-  Physics (Path integrals, Quantum tunneling, Optics, Electron Optics)
-  EE (CMOS & MEMS processes, Field emission devices, Control Theory)
-  Material Science (Generalized interference lithography)
