CPS615-Lecture on Performance(end) and Computer Technologies(start)

Given by Geoffrey C. Fox at Delivered Lectures of CPS615 Basic Simulation Track for Computational Science on 10 September 96. Foils prepared 27 october 1996

Secs 50.4

This starts by filling in details of communication overhead in parallel processing for case where "range" of interaction is large
We show two old examples from Caltech illustrates correctness of analytic form
We return to discussion of computer architectures describing
  • Vector Supercomputers
  • General Relevance of data locality and pipelining
  • Flynn's classification (MIMD,SIMD etc.)
  • Memory Structures
  • Initial issues in MIMD and SIMD discussion


This mixed presentation uses parts of the following base foilsets which can also be looked at on their own!
Master Set of Foils for 1996 Session of CPS615

CPS 615 Lectures 1996 Fall Semester -- September 10

We first finish the discussion of overhead (tcomm/tcalc) as we added a few foils that we noted last time were missing!
