Portability of Numerical Software

• Numerical software to work portability on different computers with good numerical accuracy, stability and robustness of solution.

  • EISPACK - DEC, IBM, CDC (early 70’s)
  • LINPACK - Vector, pipelined (late 70’s)
  • LAPACK - Vector, RISC, SMPs (late 80’s early 90’s)
  • ScaLAPACK (late 90’s)
    • MPP
    • DSM
    • Clumps
    • Heterogeneous NOWs
