We describe a collaborative project between an HCI team and an internationally known Japanese artist, based in New York, who was artist-in-residence with the group in the UK. The collaboration resulted in a new performance art work and a new interactive instrument. The research included a full study of the process of collaboration and innovation. We describe the work that was created, the interactive instrument developed and illustrates its use in a performance.

Growing wire delays will force substantive changes in the designs of large caches. Traditional cache architectures assume that each level in the cache hierarchy has a single, uniform access time. Increases in on-chip communication delays will make the hit time of large on-chip caches a function of a line's physical location within the cache. Consequently, cache access times will become a continuum of latencies rather than a single discrete latency. This nonuniformity can be exploited to provide faster access to cache lines in the portions of the cache that reside closer to the processor. In this paper, we evaluate a series of cache designs that provides fast hits to multi-megabyte cache memories. We first propose physical designs for these Non-Uniform Cache architectures (NUCAs). We extend these physical designs with logical policies that allow important data to migrate toward the processor within the same level of the cache. We show that, for multi-megabyte level-two caches, an adaptive, dynamic NUCA design achieves 1.5 times the IPC of a Uniform Cache architecture of any size, outperforms the best static NUCA scheme by 11%, outperforms the best three-level hierarchy-while using less silicon area-by 13%, and comes within 13% of an ideal, minimal hit latency solution.
