    88 and results can be validated using a 'fuzzy comparison' function that allows for deviations of a few percent.

    10 Other applications are 'divergent' in the sense that small numerical differences lead to unpredictably large differences in the final output.

    1112For such applications it may be difficult to distinguish between results that are correct
    1213but differ because of numerical discrepancies, and results that are erroneous.

    4243 0:: No homogeneous redundancy (all hosts are numerically equivalent)
    43  1:: A fine-grained classification with 80 classes (4 OS and 20 CPU types).
    44  2:: A coarse-grained classification in which there are 4 classes: Windows, Linux, Mac-PPC and Mac-Intel.
     44 1:: A fine-grained classification with ~80 classes.
     45 2:: A coarse-grained classification ~15 classes.
     46
     47Types 1 and 2 divide hosts by OS (Linux, Windows, Mac, FreeBSD, Android).
     48Type 2 subdivides by CPU architecture (Intel, PPC, ARM).
     49Type 1 subdivides by a finer CPU classification that distinguishes
     50Celeron, Pentium, AMD Athlon, AMD Opteron, etc..

     52NOTE: this is out of date; it doesn't reflect current CPU models.
