MPIBoost toolkit is described, which allows automating the process of selecting optimum values of parameters for S-MPI library. MPIBoost has two operation modes: setting the cluster-specific parameters and setting the application-specific parameters.
The process of setting parameters for S-MPI library conventionally has three levels:- setting the values of parameters for the most popular cluster architectures and parameters for running applications, these values are used in S-MPI library as default values;
- setting parameters of S-MPI library with regard to the specifics of a certain cluster, which is performed, if S-MPI library package is installed;
- setting parameters of S-MPI library with regard to the specifics of a certain application.
Such multilevel process allows getting an optimum ratio between the time spent for setting parameters and the performance of applications achieved on different clusters.Keywords: MPI, parallel computations, optimization methods.
