There are only 3 platforms (A=P90, B=P200, C=K2-450) which cover all of the
current programs (other than the dedicated units). But I don't think the elo/mhz
approach would work, since these are different processors (different cache,
diferent clocks/instruction, different memory bandwidth, etc). Instead one needs
to find all the "bridging" programs between any 2 of the 3 platforms (AB, AC,
BC)and obtain how the performance changes (statistically) between those two
platforms. With several such programs between any pair of platforms, one will
have a distribution of elo changes for A->B, B->C and A->C, thus one will have
an average elo change and the spread for different programs (and their original
elo uncertainties), giving the error margin for the estimate. For programs which
haven't been tested on C, but were tested on A and B one would construct 2
ratings for C using the average elo jumps A->C and B->C, and also obtain the
full error interval as the union of the A->C and B->C error intervals (or as the
sqrt(Err(AC)^2+Err(BC)^2) ). I did something like that when the list came out,
for the Tiger version they tested, and it came on top (as I recall, by a very
little, within the error margins).
