The paper discusses the use of specialized Intel Xeon Phi devices in a desktop grid system. As an example of the successful use of specialized devices, the combinatorial problem of finding diagonal Latin squares is given. Features of implementation of the computing application are discussed. The results of work of a computer application in multithreaded modes on different processors andspecialized devices are given.

With recent developments in parallel supercomputing architecture, many core, multi-core, and GPU processors are now commonplace, resulting in more levels of parallelism, memory hierarchy, and programming complexity. It has been necessary to adapt the MILC code to these new processors starting with NVIDIA GPUs, and more recently, the Intel Xeon Phi processors. We report on our efforts to port and optimize our code for the Intel Knights Landing architecture. We consider performance of the MILC code with MPI and OpenMP, and optimizations with QOPQDP and QPhiX. For the latter approach, we concentrate on the staggered conjugate gradient and gauge force. We also consider performance on recent NVIDIA GPUs using the QUDA library.
