  1. Let’s Open Up New Fieldsfor Next 10X! Koji Inoue Kyushu University, Japan ISLPED'08@Bangalore

  2. We Need More Performance! But… • High performance is exactly required more! • Supercomputing, Desktop, Laptop, Cellar Phone, Home Games, and so on • But, power is a SERIOUS problem! • Device Reliability • Grobal Warming Total Power Consumption in Japan 250 200 150 100 50 12X • Need drastic improvement! • Not Incremental! Billions KW/h 5X 2006 2025 2050 http://www.meti.go.jp/press/20071207005/03_G_IT_ini.pdf ISLPED'08@Bangalore

  3. How? • Fundamental concept for low-power has matured in “Our Current Field”! • DVS, DVFS, Selective Activation, Exploiting Prediction, and so on… • Suggestion • Move to a new (or strange) field! • Orchestrate computing resources effectively! ISLPED'08@Bangalore

  4. New Fields! • Revisit the system stack from circuit/architecture level to algorithm level on new fields! Superconducting rapid single-flux-quantum (SFQ) New Reconfigurable Devices 3D-IC Implementation with Wireless Links Yokohama National University Nagoya University Advanced Industrial Science and Technology Keio University ISLPED'08@Bangalore

  5. The Case for SFQ-RDP Project 10 TFLOPS Desk-top Computer RSFQ with new architecture Kyushu University, Yokohama National University, Nagoya University, SRL/ISTEC ISLPED'08@Bangalore

  6. Superconducting rapid single-flux-quantum (SFQ) : Device Level Energy-delay products Superconducting wire Ballistic propagation Bit energy [J] MCM developed by SRL ISLPED'08@Bangalore Gate delay [s]

  7. Large-Scale Reconfigurable Data-Path for SFQ : Architecture Level • 1K FPUs operate at 80 GHz • Re-configurable operand network • Much simple organization for SFQ design (No feedback loops) • Make a good balance between “Parallel Exe. Vs. Sequential Exe.” ISLPED'08@Bangalore

  8. How To Exploit A Number of FPUs: Compiler Level Application Program • Large DFGs are extracted from source codes • They are executed in pipeline fashion • SFQ-RDP is used as an “Efficient Accelerator” DFG Extractor (w/ source level optimization) Mapping ISLPED'08@Bangalore

  9. How To Exploit A Number of FPUs: Algorithm Level Computation of molecular orbital while (I < 1000): tei(4,4,4,4)=(((3+2*p*(4*PAx*PBx+PBx**2+PAx**2*(1+2*p*PBx**2)))*(3+2*q*(4*QCx*QDx+QDx**2+QCx**2*(1+2*q*QDx**2)))*f(0,t))/(p**2*q**2)+(4*(3+2*p*(4*PAx*PBx+PBx**2+PAx**2*(1+2*p*PBx**2)))*PQx*(QCx+QDx)*(3+2*q*QCx*QDx)*f(1,t))/(p*q*(p+q))(4*(PAx+PBx)*(3+2*p*PAx*PBx)*PQx*(3+2*q*(4*QCx*QDx+QDx**2+QCx**2*(1+2*q*QDx**2)))*f(1,t))/(p*q*(p+q))(8*(PAx+PBx)*(3+2*p*PAx*PBx)*(QCx+QDx)*(3+2*q*QCx*QDx)*(((p+q)*f(1,t))+2*p*PQx**2*q*f(2,t)))/(p*q*(p+q)**2)+(2*(3+2*p*(4*PAx*PBx+PBx**2+PAx**2*(1+2*p*PBx**2)))*(3+q*(QCx**2+4*QCx*QDx+QDx**2))*(((p+q)*f(1,t))+2*p*PQx**2*q*f(2,t)))/(p*q**2*(p+q)**2)+(2*(3+p*(PAx**2+4*PAx*PBx+PBx**2))*(3+2*q*(4*QCx*QDx+QDx**2+QCx**2*(1+2*q*QDx**2)))*(((p+q)*f(1,t))+2*p*PQx**2*q*f(2,t)))/(p**2*q*(p+q)**2)+(4*(3+2*p*(4*PAx*PBx+PBx**2+PAx**2*(1+2*p*PBx**2)))*PQx*(QCx+QDx)*(3*(p+q)*f(2,t)+2*p*PQx**2*q*f(3,t)))/(q*(p+q)**3)\+(8*(3+p*(PAx**2+4*PAx*PBx+PBx**2))*PQx*(QCx+QDx)*(3+2*q*QCx*QDx)*(3*(p+q)*f(2,t)+2*p*PQx**2*q*f(3,t)))/(p*(p+q)**3)(8*(PAx+PBx)*(3+2*p*PAx*PBx)*PQx*(3+q*(QCx**2+4*QCx*QDx+QDx**2))*(3*(p+q)*f(2,t)+2*p*PQx**2*q*f(3,t)))/(q*(p+q)**3)(4*(PAx+PBx)*PQx*(3+2*q*(4*QCx*QDx+QDx**2+QCx**2*(1+2*q*QDx**2)))*(3*(p+q)*f(2,t)+2*p*PQx**2*q*f(3,t)))/(p*(p+q)**3)+((3+2*p*(4*PAx*PBx+PBx**2+PAx**2*(1+2*p*PBx**2)))*(3*(p+q)**2*f(2,t)+4*p*PQx**2*q*(3*(p+q)*f(3,t)+p*PQx**2*q*f(4,t))))/(q**2*(p+q)**4)(8*(PAx+PBx)*(3+2*p*PAx*PBx)*(QCx+QDx)*(3*(p+q)**2*f(2,t)+4*p*PQx**2*q*(3*(p+q)*f(3,t)+p*PQx**2*q*f(4,t))))/(q*(p+q)**4)(8*(PAx+PBx)*(QCx+QDx)*(3+2*q*QCx*QDx)*(3*(p+q)**2*f(2,t)+4*p*PQx**2*q*(3*(p+q)*f(3,t)+p*PQx**2*q*f(4,t))))/(p*(p+q)**4)+(4*(3+p*(PAx**2+4*PAx*PBx+PBx**2))*(3+q*(QCx**2+4*QCx*QDx+QDx**2))*(3*(p+q)**2*f(2,t)+4*p*PQx**2*q*(3*(p+q)*f(3,t)+p*PQx**2*q*f(4,t))))/(p*q*(p+q)**4)+((3+2*q*(4*QCx*QDx+QDx**2+QCx**2*(1+2*q*QDx**2)))*(3*(p+q)**2*f(2,t)+4*p*PQx**2*q*(3*(p+q)*f(3,t)+p*PQx**2*q*f(4,t))))/(p**2*(p+q)**4)(4*p*(PAx+PBx)*(3+2*p*PAx*PBx)*PQx*(15*(p+q)**2*f(3,t)+4*p*PQx**2*q*(5*(p+q)*f(4,t)+p*PQx**2*q*f(5,t))))/(q*(p+q)**5)+(8*(3+p*(PAx**2+4*PAx*PBx+PBx**2))*PQx*(QCx+QDx)*(15*(p+q)**2*f(3,t)+4*p*PQx**2*q*(5*(p+q)*f(4,t)+p*PQx**2*q*f(5,t))))/(p+q)**5+(4*PQx*q*(QCx+QDx)*(3+2*q*QCx*QDx)*(15*(p+q)**2*f(3,t)+4*p*PQx**2*q*(5*(p+q)*f(4,t)+p*PQx**2*q*f(5,t))))/(p*(p+q)**5)(8*(PAx+PBx)*PQx*(3+q*(QCx**2+4*QCx*QDx+QDx**2))*(15*(p+q)**2*f(3,t)+4*p*PQx**2*q*(5*(p+q)*f(4,t)+p*PQx**2*q*f(5,t))))/(p+q)**5+(8*(PAx+PBx)*(QCx+QDx)*(15*(p+q)**3*f(3,t)+30*p*PQx**2*q*(p+q)*(3*(p+q)*f(4,t)+2*p*PQx**2*q*f(5,t))8*p**3*PQx**6*q**3*f(6,t)))/(p+q)**6+(2*(3+p*(PAx**2+4*PAx*PBx+PBx**2))*(15*(p+q)**3*f(3,t)30*p*PQx**2*q*(p+q)*(3*(p+q)*f(4,t)+2*p*PQx**2*q*f(5,t))+8*p**3*PQx**6*q**3*f(6,t)))/(q*(p+q)**6)+(2*(3+q*(QCx**2+4*QCx*QDx+QDx**2))*(15*(p+q)**3*f(3,t)30*p*PQx**2*q*(p+q)*(3*(p+q)*f(4,t)+2*p*PQx**2*q*f(5,t))+8*p**3*PQx**6*q**3*f(6,t)))/(p*(p+q)**6)  787 MUL, 261 ADD, 69 FUNC I ++: ISLPED'08@Bangalore
