ZeptoOS is a research project studying operating systems for petascale architectures with 10,000 to 1 million CPUs.

Operating system and run-time software is strained by ultra-scale machines, and a variety of fascinating research topics are revealed at such amazing scale. Archtectures such as IBM’s BlueGene and Cray’s XT3 are on the path toward petaflops and beyond, and make perfect testbeds for computer science explorations.

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