Perhaps the most interesting conversation that has happened so far in the White House in 2025, at least from the point of view of the IT sector, is when Nvidia co-founder and chief executive officer, Jensen Huang, put on his Sunday best suit and visited President Donald Trump to presumably talk about technology, AI, trade, and war on July 10. …
Making a graphics card for gamers is one thing, but manufacturing a rackscale supercomputer with over 600,000 components that burns 120 kilowatts of power, that has over 5,000 copper cables for an all-to-all interconnect mesh for 72 dual-chip compute engines, and that weighs over 3,000 pounds is another thing entirely. …
Each time that the United States has figured out that it needed to do export controls on massively parallel compute engines to try to discourage China from buying such gear and building supercomputers with them, it has already been too late to have much of a long term effect on China’s ability to run the advanced HPC simulations and AI training workloads that we were worried would be enabled by such computing oomph. …
