Heterogeneous Computing with Nanoscale Architectures for Bio Applications

Abstract: Heterogeneous computing is a special form of parallel and distributed computing that could be applied to different levels of a diverse computing organization. My 1996 book “Heterogeneous Computing” presented heterogeneous computing at two levels: network level and system level. Here, I’ll present a third level, architecture level, to which heterogeneous computing can also be applied. In architecture-level heterogeneous computing, the diversity is in the underlying technologies that are used at the chip level. For example, the chips may be multi-scale with both nano and MEMS components, and/or may operate with both analog and digital signals, and/or may employ both electrical and optical interconnects, and/or may use both classical and quantum computations. Research in architecture-level heterogeneous computing is very new and poses many challenging problems. To demonstrate the types of complexities involved in solving problems on such chips, I will present a set of bioinformatics algorithms using the new spin-wave nanoscale architectural modules that my collaborators and I have recently developed at UCLA. The significance of the new spin-wave designs is that the communication between the nodes can be done in constant time, which is a noteworthy improvement over the Ω(log N) lower-bound on the time delay to implement such networks in VLSI using traditional electrical interconnects. In these architectures, unlike traditional spin-based architectures that transmit charge, the information is encoded into the phase of spin waves. As a result of this, the presented nanoscale designs may have low power consumption and can operate at room temperature.
