ZeptoOS is a research project studying operating systems for petascale architectures with 10,000 to 1 million CPUs. Operating systems and run-time software are strained by ultra-scale machines, and a variety of fascinating research topics are revealed at such amazing scale. Archtectures such as IBM’s Blue Gene and Cray’s XT are capable of achieving petaflops performance and beyond, and make perfect testbeds for computer science explorations.

Our current activities focus on IBM Blue Gene/P, where we provide a complete, flexible, high-performance software stack, including a Linux-based compute node kernel, HPC communication libraries, I/O forwarding, and performance analysis.

The ZeptoOS project is a collaboration between Argonne National Laboratory and the University of Oregon.
