Template:mpu Matrix-2000 is a 128-core many-core processor designed by NUDT and introduced in 2017. This chip was designed exclusively as an accelerator for China's Tianhe-2 supercomputer in order to upgrade and replace the aging Intel's Knights Corner accelerators after the Obama administration banned the sale of high-performance accelerators to China. The Matrix-2000 features 128 RISC cores operating at 1.2 GHz achieving 2.46 TFLOPS with a peak power dissipation of 240 W.
Overview
The original TianHe-2 (Milkyway-2) was powered by 16,000 servers consisting of Intel's Xeon and Xeon Phi accelerators. Those accelerators were based on Knights Corner. Originally, NUDT announced they would be upgrading the supercomputer to Intel's then-latest Phi Knights Landing accelerators. The new supercomputer was renamed 'TianHe-2A'. In February 2015, under the Obama administration, the Department of Commerce blacklisted NSCC-G (the site of the TianHe-2A) and NUDT as well as the previous supercomputer center. The DoC cited concerns regarding nuclear explosive devices and other related computer research and simulations.
Chuck Mulloy, an Intel spokesperson later gave the following statement:
Intel was informed in August by the U.S Department of Commerce that an export license was required for the shipment of Xeon and Xeon Phi parts for use in specific previously disclosed supercomputer projects with Chinese customer INSPUR. Intel complied with the notification and applied for the license which was denied. We are in compliance with the U.S. law. Stay tuned as HPCwire brings you more coverage of this developing story as it unfolds.
Due to the ban NUDT was unable to obtain the Xeon Phis they've hoped for in order to upgrade the system. To achieve the desired upgrades without the embargoed parts, NUDT developed the Matrix-2000 accelerators. While not nearly as powerful as Knights Landing, the chips were more powerful than the first-generate Knights Corner parts they have replaced. While original (KL) system was planned to exceed 110 PFLOPS using the Intel parts, the Matrix-2000 managed to achieve 94.97 PFLOPS.
