high-order methods - Opis:
- The paper presents a hybridMPI+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 andMPI whichdiffer in terms of memory on which they are based. OpenMP works on shared-memory and the MPIon 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 ofMPI, Open-MP and Hybrid of both tools were carried out using anacademic high-order SAILORsolver. The obtained results seem to be very promising to accelerate simulations of fluid flows as well as for application using high order methods.
