Abstract In article is researched the actual problem of relief and landscapes image-synthesis, the basic algorithms for its realization is considered and efficiency of real time relief image-synthesis by algorithm ROAM for popular modern specialized parallel computing systems is researched. It is carried out research of efficiency of ROAM- realization on the modern videocards parallel GPU with use of CUDA- technology and cluster architecture NeClus with use of MPI- technology, and some parameters of process of synthesis are received. It is shown, that in view of absence of support by CUDA- technology of recursive calculations and dynamic trees structures the ROAM-realization use CUDA is inefficient, and use computing cluster and MPI for the organization of parallel calculations for ROAM is effective, and allowing real time relief and landscapes imagesynthesis.
