Claim 0:
1. A method for autotuning a high-performance computing system, at least part of the high-performance computing system having an evaluable performance and being able to be parameterized using a set of parameters, each parameter having at least one value, the evaluable performance being dependent on values of parameters of the set of parameters, the method being carried out by a computing device, an optimization module being configured to generate at least one current value of at least one parameter of the set of parameters as a function of at least one previously measured performance of the high-performance computing system, the method comprising:
if the evaluable performance has not been evaluated at least a predetermined number of times with current values of the set of parameters:
evaluating the evaluable performance of the high-performance computing system with the current values of the set of parameters;

if the evaluable performance has been evaluated at least said predetermined number of times with the current values of the set of parameters:
computing a median of evaluated performances with the current values of the set of parameters,
if the median of said evaluated performances does not verify a rule based on a filtering threshold, discard the current values of the set of parameters and restart the method with at least one other value for said at least one parameter of the set of parameters generated by the optimization module,
if the median of said evaluated performances verifies the rule based on the filtering threshold, performing a resampling method based on the median of the evaluated performances and on a confidence interval decreasing with a number of steps of the optimization module.
