Cathy can take many forms, depending on the time of year.

I’m a Ph.D in Computer Science, specialized in the field of HPC and performance analysis. I work with François Trahay and Valentin Honoré. I’d like to say this page is a WIP but it isn’t, not really.

My thesis

My work is focused on Pallas, a new trace format built for HPC. I’ve presented it at IPDPS25, and proved it was a highly scalable trace format, which did not disturb the application during the runtime, and could be used to perform fast and scalable post-mortem performance analysis.

About me

Things I like

• Board games, especially long ones, such as Root or Terraforming Mars.
• Rock dancing (although I’m not that good at it)

Things I don’t

• HTML
• Designing web-pages

This random collection of niche things I find neat

• A paper implementing a transactional memory system in the Quake engine to test performance.
• A comic set in the Project Moon universe, during the events of Lobotomy Corporation. Send me an email if the link dies.
• A font that tries to imitate the “Objections !” from the Ace Attorney games. I just think they’re neat.
