Date of Defense 2006-05-31 Availability unrestricted Abstract Computer architecture is plagued by the von Neumann bottleneck. This workintroduces and evaluates the traveling thread execution model in which threads mi-
grate to the memory resources close to the data they require rather than perform
remote memory accesses. This helps address the von Neumann problem by exposing
additional concurrency within programs to tolerate long memory latencies, reduces
two-way request/response network transactions typical of caching architectures to
one way thread migration transactions, and reduces or eliminates cache coherency
traffic.
