Essential guide to HPC on twitter

Who are the best HPC people on twitter?

A good question posed by Suhaib Khan (@suhaibkhan) - which he made tougher by saying "pick your top 5". A short debate followed on twitter but I thought the content was useful enough to record in a blog post for community reference. I also strongly urge anyone to provide further input to this topic and I'll update this post.

Some rules (mine not Suhaib's):
  1. What are the minimum set of accounts you can follow and still expect to catch most of the HPC news, gossip, opinion pieces, analysis and key technical content?
  2. How to avoid too much marketing?
  3. How to access comment and debate beyond the news headlines?
  4. Which HPC people are not only active but also interactive on twitter?
I cheated a little on the "top 5" by suggesting 4 themes:

  • describe system architecture as "the art of balancing the desires of capacity, performance and resilience against the frustrations of power, cooling, dollars, space, and so on";
  • introduce software as magic and infrastructure and a virtual knowledge engine;
  • and note that "delivering science insight or engineering results from [supercomputing] requires users";
  • and propose that we need a roadmap for people just as much as for the hardware technology.
