Foil 48 Pragmatic Computational Science January 2000 II

From Methodology of Computational Science CPS615 Computational Science -- Spring Semester 2000. by Geoffrey C. Fox


1 We don't emphasize openMP in class, as hard work (aka difficult programming model) of MPI is advantageous for class as teaches you parallel computing!
2 Today Java can be used for client side applets and in systems middleware but too slow for production scientific code
  • This should change over next year with better Java compilers -- including "native" compilers which do not translate to Java Virtual Machine but go directly to native machine language
3 Use metacomputers for pleasingly parallel and metaproblems -- not for closely knit problems with tight synchronization between parts
4 Use where possible web and distributed object technology for "coordination"
