示例1: calibrate_and_save
// currently, this method checks if there if a file already exists, and if so, assumes it is valid.
// ideally, a check should be made to ensure the saved SSD state matches with the state of the current global parameters
void Experiment::calibrate_and_save(Workload_Definition* workload, string name, int num_IOs, bool force) {
//string file_name = base_folder + "calibrated_state.txt";
string file_name = base_folder + name;
std::ifstream ifile(file_name.c_str());
if (ifile && !force) {
return; // file exists
}
