Hi,

Is there any literature discussing how suitable it is to use

least-square fitting to get the performance model of a set of

benchmarks? What I read so far is that: given a set of benchmarks,

decide what the performance factors there are, and then use the

least-square fitting to get the coefficient of each performance

factor. This model is then used to predict other

programs/benchmarks. Is there any other way to get the performance

model, besides the one which estimates the cost(time) of each

primitive operation, and count the number of that operation in the

program to predict the performance.
