Glenn K. Lockwood: Oakland, California, United States; I'm Glenn, and this blog is where I conduct experiments in understanding—writing to clarify my own thoughts on high-performance computing, storage architecture, and systems design. I’ve spent much of my career working in HPC, particularly on the hardware, integration, and I/O aspects that keep large-scale systems running. This blog isn’t an authoritative source, nor do I claim to be an expert on everything I write about. It’s simply where I reflect on ideas, document things I learn, and sometimes challenge conventional thinking in supercomputing.
