Popis
Shrnutí:A method of performing parallel computations based on the MPI standard and implemented in the EVKLID-V1 integrated code for safety validation of metal-cooled reactor installations is presented, and the results of speeding-up the calculation of power maneuvering of a lead-cooled reactor are presented. The minimum parallelization efficiency was about 50% with 15-fold speed-up on 28 cores. The results obtained show that integrated code EUCLID/V1 can be used effectively in computing systems with distributed memory.
