Hello.
My name is Hyunsun Chung. I also go by Horace in the English speaking part of the world. Welcome to my obligatory “corner of the internet”.
I’m working to be a well-rounded computer systems engineer in all regards, from operating systems to storage.
With that said, I’m not much of a web design guru, so you’ll have to make do with a template I found lying around.
Anyways, enjoy your time here with the little stuff I’ve got here.
Research Interests
Next generation storage devices
Experimental NAND flash based storage and their operating system/file system support.
Emerging memory device concepts
Tiered memory systems and experimental CXL memory devices.
LLM inference optimization
Attention offloading and smart KV cache reuse.
