Details of the Chinese-made high performance CPU 'Sunway SW26010 Pro' equipped with 384 cores are released

The detailed specifications of the supercomputer CPU 'Sunway SW26010 Pro' have been released. Designed based on a proprietary 64-bit RISC architecture, the new CPU is expected to enable China to build high-performance supercomputers using only domestically produced processors.

According to information released at the international conference on supercomputers ' SC23 ', the SW26010 Pro is equipped with 384 cores, the maximum throughput of FP64 is 13.8TFLOPS, and the maximum throughput of FP32 is 27.6TFLOPS. This SW26010 Pro is said to be installed in a 'new generation' supercomputer.

The SW26010 Pro maintains the basic architecture of the previous model's 256-core CPU 'Sunway SW26010', but has several new features such as six core groups and a protocol processing unit based on a new proprietary 64-bit RISC architecture. has improved its functionality. In addition to a higher number of cores, the microarchitecture and system architecture improvements have increased FP64 computational throughput by more than 4x. On the other hand, it has been pointed out that the cache and memory subsystem have limitations and are a bottleneck.

According to the announcement, the supercomputer equipped with the SW26010 Pro ranks in the top 2 in the benchmark 'HPL-MxP' related to single-precision and half-precision arithmetic processing mainly used in deep learning of artificial intelligence, and 'LUMI' of HPC/CSC It is said that it showed performance superior to Fujitsu's ``Fugaku''.

Overall, the SW26010 Pro is a big step forward from the SW26010 in terms of memory capacity, computational density, and overall performance, but it is a CPU that has the disadvantage that optimization takes time and cost due to memory constraints. It is being evaluated. However, it is hoped that the development of this new CPU will enable China, which suffers from export restrictions from the United States, to build supercomputers using only domestically produced processors.
