  • China dominated the Top500 list by 2017, with 202 machines compared to 143 from the U.S. Then the U.S. restricted Chinese access to Intel processors and other U.S. hardware in 2015, followed by broader export restrictions under the Trump administration in 2019, which have been tightened further by the Biden administration in 2022. As a result, Chinese participation in the Top500 list dwindled, to some degree because access of Chinese entities to the latest hardware got harder and to some degree because Chinese scientists no longer want to share details about their machines with anyone.

    Why is anyone surprised that the country with the highest research output, that has historically dominated the Top500 list, has the fastest supercomputers?








  • If you’re committed to word-style documents instead of LaTeX, pandoc is a great way to convert between word and the style of your choice (for me, markdown). I made a bunch of additional scripts to assist in conversion between the two.

    That said, LaTeX is often a better choice. I’ve settled into a combination of overleaf / git / vscode / LaTeX that keeps my collaborators (and myself) happy.


  • I gave up on linux because it made academic collaboration difficult as a grad student. I spent too long trying to make a system to bridge the gap between mac/windows and linux, and not enough time on research. Professors don’t care that you use arch btw, they just want results, and will not be forgiving if you explain that linux is what’s slowing you down.
