Modern GPGPU Alternative Perspective Universal and Specialized Processors-Accelerators
Three variants of a domestic accelerator processor are considered to replace modern foreign GPGPUs in domestic supercomputers and high-performance computing systems. The first variant corresponds to the result of the supposed evolutionary development of foreign GPGPUs, which was proposed in the Echelon project of NVIDIA / Cray firms. It is possible to create a corresponding domestic version of such a GPGPU, if we use one of the results of the HEC Angara project, an existing FPGA realization of the 64-thread J7 microprocessor. The second option is similar to the GPGPU substitute developed on the basis of the vector processor and called the FT-Matrix2000 GPDSP. This option can be realized by redevelopment of the ideologically close domestic vector processor NM6408MP (VLSI 1879BM8Я). The third option is a multi-tile processor, a type of GreenDroid architecture, in each tile there are 64 thread kernel and 64 KB static memory, the core is focused on efficient work with many specialized hard-functional devices connected to it.
