In the name of national security, China is restricting export of certain drones and computers:
From August 15, manufacturers of certain powerful drones and computers will have to give technical details to the authorities to obtain a licence prior to export, Xinhua news agency says.
[...] In the first five months of 2015, China exported some 160,000 civilian drones, a jump of 70 per cent year-on-year, worth more than $120 million, the official China Daily newspaper reported in July.
[...] The tightening of regulations comes two weeks after an incident in disputed Kashmir in which the Pakistani army claimed to have shot down an Indian "spy drone", reportedly Chinese-made.
China is also likely tightening controls on exports of powerful computers as it looks to maintain its edge in the global supercomputer battle long dominated by US-Japanese rivalry.
Starting August 15th, drone and supercomputer manufacturers will have to present technical details to the authorities in order to get a license to export.
According to VR World and HPCwire, the U.S. government has blacklisted "high technology" shipments to the National Supercomputing Center Changsha (NSCC-CS), National Supercomputing Center Guangzhou (NSCC-GZ), National Supercomputing Center Tianjin (NSCC-TJ), and the National University of Defense Technology (NUDT) in China. This effectively means that these major supercomputing facilities can no longer purchase Intel Xeon chips. Tianhe-2, the world's fastest supercomputer since June 2013 according to Top500, is located at the NUDT in Guangzhou and uses a total of 32,000 Intel Xeon and 48,000 Xeon Phi chips.
The main claim of the Bureau of Industry and Security's End-User Review Committee (ERC) is that NUDT, which used US-manufactured parts to produce the Tianhe-1A and Tianhe-2 supercomputers located at the National Supercomputing Centers in Changsha, Guangzhou, and Tianjin, is believed to be engaged in activities related to nuclear explosives.
The U.S. also uses supercomputers for nuclear weapons research.
The news coincides with the Intel Developer Forum 2015 in Shenzhen, China, at which the company announced new Braswell, SoFIA, and Cherry Trail chips, among other products. VR World speculates that the move could cost Intel $1 billion on lost Broadwell-EP Xeon E5v4 sales and accelerate the development of homegrown Chinese processors.
The Platform reports that CPU export restrictions to Chinese supercomputing centers may have backfired. Tianhe-2 has remained the world's top supercomputer for the last five iterations of the TOP500 list using a heterogeneous architecture that mixes Intel's Xeon and Xeon Phi chips. Tianhe-2 will likely be upgraded to Tianhe-2A within the next year (rather than by the end of 2015 as originally planned), nearly doubling its peak performance from 54.9 petaflops to around 100 petaflops, while barely raising peak power usage. However, instead of using a new Intel Xeon Phi chip, a homegrown "China Accelerator" and novel architecture will be used.
A few details about the accelerator are known:
Unlike other [digital signal processor (DSP)] efforts that were aimed at snapping into supercomputing systems, this one is not a 32-bit part, but is capable of supporting 64-bit and further, it can also support both single (as others do) and double-precision. As seen below, the performance for both single and double precision is worth remarking upon (around 2.4 single, 4.8 double teraflops for one card) in a rather tiny power envelope. It will support high bandwidth memory as well as PCIe 3.0. In other words, it gives GPUs and Xeon Phi a run for the money—but the big question has far less to do with hardware capability and more to do with how the team at NUDT will be able to build out the required software stack to support applications that can gobble millions of cores on what is already by far the most core-dense machine on the planet.
