NUDT Matrix-2000
Chinese-designed many-core DSP accelerator that replaced the US Xeon Phi cards in Tianhe-2A after export restrictions.
Why this part
The direct replacement for the Xeon Phi parts the United States blocked in April 2015, designed by NUDT and deployed in the Tianhe-2A rebuild. Whatever one concludes about the wider policy, this instance is legible: an export control removed a component, and the response was to build one. It is also the reason era-scoped component edges exist in this dataset at all, because Tianhe-2's accelerator supplier changed midway through the machine's life.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
