Jon Howell and David Kotz. Snowflake: A Worldwide Virtual Computer For Every User. January 1997. Unpublished manuscript.

Abstract: A system that allows users to access a distributed collection of resources transparently, as if they were all part of a single computer system, is said to have a single-system "image." The best current single-system-image designs do not span administrative boundaries, and thus still impose multiple system images on users who have accounts at sites in several administrative domains. In this paper, we propose a system that allows each computer user to aggregate resources from multiple sites into his own single distributed virtual computer. Another difference between our design and typical single-system-image cluster designs is that almost all of the aggregation and abstraction functions in our design are implemented in the user's environment, so the end user can replace and reconfigure them at will.
