Abstract: A method for optimizing the run parameters of a software application on an information processing platform, consisting of iteratively optimizing said parameters on each execution of said application, wherein, for each execution of said application (11),



a set of said parameters is determined and a run time of said application with said parameters is determined, and an association between said set and said run time is stored in order to create a history (25); and wherein
said set is determined by implementing a genetic optimization algorithm comprising a step (21) consisting of selecting two sets of parameters from said history; a step (22) consisting of creating a new set of parameters by recombining said two sets of parameters; and a step (23) of random mutation of said new set of parameters.

Abstract: The invention relates to a method for optimizing the execution parameters of a software application on an information processing platform, consisting in iteratively optimizing said parameters at each execution of said application, in which:



for each execution (1) of said application, performance measurements are made (2) and stored (3), in association with the parameters used for said execution;
at the start of each execution of said application, values are determined (4, 6) for a first subset of said parameters by inference (6) from the stored measurements corresponding to a subset of the executions corresponding to a second subset of said parameters.

Abstract: The method for preloading data of a file containing the following steps of defining a plurality of bins of predetermined sizes in a file, for each input and/or output operation executed on the file, determining the bin involved in the operation, counting the number of input and/or output operations executed in each bin of the file by taking into account only a predetermined number of last operations on the whole file, and when the sum of the operations counted in a bin is greater than a predetermined threshold, loading, in a memory medium, at least one area of the file determined on the basis of this bin.
