Paper Abstract:	The computing power and complexity of computation architecture of modern computer systems used for image rendering is constantly rising, so effective parallelization of rendering methods is an urgent challenge. Modern workstations might have several CPUs with NUMA that makes traditional parallelization methods ineffective and requires research of the new approaches. In the scope of the current research, authors present a CPU parallelization algorithm for bidirectional ray tracing with photon maps that use three-level parallelization thread architecture and asynchronous calculations to achieve the high rendering scalability.
