Надійнісна модель відмовостійкої багатопроцесорної системи з відновленням працездатності програмного забезпечення

Introduction. The analysis of the researched problem and features of the designed fault-tolerant hardware/software systems were carried out. The approach description to developing reliability models of the software/hardware sys-tem. This chapter outlines a reliability macromodel of a fault-tolerant multicore system with a software recovery. Model of the fault-tolerant multicore system. The model features include: two multicore systems (main and reserve), some processors for sliding redundancies, one control and diag-nostics processor which controls the hardware and software features. Also this model in-cludes the automatic software restart after hardware failure. The proposed model appication example. Weighed calculation of MTTF (mean time to failure) considering given probability of infallible performance of the suggested and existing models was performed. Conclusion. The proposed model is designed to estimate reliability of the hard-ware/software systems.
