Managing Scheduled Routing With A High-Level Communications.. - Metcalf (1997) (1 citation) (Correct)
....as well, but this is costly in terms of pin resources and or buffer management. In [2] a comparison of dynamic routers is given, breaking down all the components of the cost. A simple deterministic router s cycle time is quoted at 9.8 ns, with a simple planaradaptive router taking 11.4 ns. In [56], Shoemaker uses these component estimates to derive an estimate for the cycle time of a scheduled router using the same technology. He finds that the NuMesh scheduled router s cycle time is constrained only by the time for a single cross node transfer, 4.9 ns. This is 50 of the deterministic ....
....well as compilers for image processing and the like. Overall, iWarp is the existing system closest to the reprogrammable scheduled routing system targeted by COP in this thesis, and their results were very promising. NuMesh extends upon their work in several ways, as discussed more extensively in [56]; in particular, NuMesh allows faster communications, more precise control over stream bandwidths, and faster phase changing and other router modifications. 3.2.2 GF11 The GF11 parallel computer from Yorktown [5] is a SIMD architecture with 576 processors and an unusual interconnect. The ....

....(Section 7.3 provides an example where dimensional routing in particular would produce poor results. 12 Finally, off line techniques allow for simpler (and therefore potentially faster) hardware implementations, since they do not incur the overhead of making routing decisions at run time [Sh97]. For a complete comparison of on line and off line routing, see [Me97] 1.2 Road Map of Thesis Chapter 2 summarizes the NuMesh, the hardware for which Tadpole generates output. Chapter 3 presents a framework for attacking the off line routing problem in systems similar to the NuMesh. It is this ....

Chapter 7 presents a collection of simple example routing problems and Tadpole s performance on them. 131313 Chapter 2 The NuMesh A complete description of the NuMesh architecture is given in [Sh97]. The following is a minimal summary adequate for an understanding of Tadpole. 2.1 Overview The NuMesh is a programmable communication substrate providing the intercommunication facility for a collection of processing elements (e.g. Sparc CPUs) The substrate provides virtual channels, which we ....

....this simple example is trivial to schedule, more complicated applications provide more complicated communication schedules that often require multiple phases of communication in order to complete. 4 Software Environment While the hardware architecture to support the NuMesh system was described in [5], a strong software environment has been created to allow for the creation of parallel applications. The Communications OPerator language (COP) is a high level parallel language that provides complex application semantics that automatically map down to the NuMesh hardware. The Tadpole compiler ....
