Heya, I'm Junxian Ma, aka EdgeP - About Me Writings Projects GitHub CV

I am a CS student at Tsinghua University. My recent work centers on AI infrastructure and pretraining algorithms, especially the co-design of model architectures and efficient GPU systems.

Research interests: AI infrastructure, pretraining algorithms, language models, efficient attention, and algorithm-system co-design.

Here are some things I believe in:

• Strong pretraining algorithms depend on equally strong infrastructure
• Model architecture and systems should be designed together
• Hardware constraints are part of the algorithm, not an afterthought
• Good research taste compounds when you write things down
• Small tools can change the shape of a week
• Clear thinking is often a design problem

Here are some things I like:

• Pretraining systems, GPU kernels, attention mechanisms, clean abstractions, quiet libraries, fast feedback loops, command lines, elegant notes, diagrams that explain themselves, and people who ask precise questions.

Things I am working on:

• GitHub: code, notes, and unfinished ideas.
• CV: a more formal snapshot of my work.
• edgep.me: this small home on the internet.

Writings:

• Notes and essays Markdown-powered
