Foil 52 Why is it hard to use HPCC in Manufacturing-I?

From NASA/MADIC NII Requirements for ASOP Langley Review NASA/MADIC Langley Review on NII Requirements for ASOP -- July 26-27 1995 NASA Langley Virginia. by Geoffrey C. Fox * See also color IMAGE

Return on Investment Unclear:
  • Amdahl's law for use of HPCC in Industrial Simulation
    • If Simulation was only 10% or less of original design and manufacturing cycle, then can only gain this 10% by speeding up simulation
    • And this speedup comes at huge software engineering cost !
    • Codes are long and expertise to convert to parallelism may no longer exist in new "slim" companies after layoffs , buyouts and freeze on hiring new employees with knowledge of new technologies such as HPCC
    • New codes must be validated by extensive tests before use
    • Remember we can't solve full Navier-Stokes Equations yet and so some approximations necessary
The Industry is in a very competitive situation and focussed on short term needs
