Spintronic Domain-Wall Memory (DWM), provides near-SRAM read/write performance, energy savings and non-volatility, potential for extremely high storage density, and does not have significant endurance limitations. However, DWM does suffer from overheads and fault-modes from shifting. Processing-in-memory (PIM) is a popular solution to reduce the demands of memory-to-processor communication by offloading computation directly to the memory. In this talk I will present CORUSCANT, a DWM-based in-memory computing solution that leverages the properties of DWM nanowires and allows them to serve as polymorphic gates. While normally DWM is accessed by applying spin polarized currents orthogonal to the nanowire at access points to read individual bits, transverse access along the DWM nanowire allows the differentiation of the aggregate resistance of multiple bits in the nanowire, akin to a multi-level cell. CORUSCANT leverages this transverse access to implement multi-operand bulk-bitwise logic, multi-operand addition, and two operand multiplication. We extend this to floating-point operations in POD-RACING. I will talk about the performance and energy efficiency of using CORUSCANT and POD-RACING on deep learning inference and training. I will also consider the holistic carbon implications of this technologies through some predicted life-cycle assessment of CORUSCANT/POD-RACING compared to other acceleration technologies.
Alex K. Jones received the BS degree in 1998 in physics from the College of William and Mary in Williamsburg, VA, USA, and the MS and PhD degrees in 2000 and 2002, respectively, in ECE from Northwestern University, Evanston, IL, USA. He is a Professor of ECE and CS at the University of Pittsburgh, Pittsburgh, PA, USA. He is currently serving as a Program Director at the US NSF in the CNS Division of the CISE Directorate. Dr. Jones' research interests include compilation for configurable systems and architectures, scaled and emerging memory, reliability, fault tolerance, quantum computing, and sustainable computing. He is the author of more than 200 publications in these areas. His research is funded by the NSF, DARPA, NSA, and industry. He is an active member of program committees in the computer architecture, design automation, and sustainable computing areas. He is the steering committee chair for the IEEE International Green and Sustainable Computing Conference, an associate editor for the IEEE Transactions on Computers, and Sustainable Computing: Informatics and Systems Journal. He is a senior member of the IEEE and the ACM. Alex is also an active musician, he is the principal clarinetist of the Pittsburgh Philharmonic and freelance musician active with local orchestras and chamber music.
