ABSTRACTThe paper presents a hybrid MPI+ OpenMP (Message Passing Interface/Open
Multi-Processor) algorithm used for parallel programs based on the high-order compact method.
The main tools used to implement parallelism in computations are OpenMP and MPI which
differ in terms of memory on which they are based. OpenMP works on shared-memory and
the MPI on distributed-memory whereas the hybrid model is based on a combination of
those methods. The tests performed and described in this paper present significant advantages
provided by a combination of the MPI/OpenMP approach. The test computations needed for
verifying possibilities of MPI, Open-MP and Hybrid of both tools were carried out using an
academic high-order SAILOR solver. The obtained results seem to be very promising to accelerate
simulations of fluid flows as well as for application using high order methods
