A distributed function computer with dedicated processors

Scheduling multiprocessor tasks on dedicated processors

Programmable stream processors - Computer

T he complexity of modern media processing, including 3D graphics, image compression, and signal processing, requires tens to hundreds of billions of computations per second. To achieve these computation rates, current media processors use special-purpose architectures tailored to one specific application. Such processors require significant design effort and are thus difficult to change as med...

Speculative multithreaded Processors - Computer

S emiconductor technologies—along with innovative computer architectures—have provided the bricks and mortar for building phenomenal improvements in processing speed during the past decade, culminating ultimately in the hundreds of millions of transistors used to build increasingly fast on-chip devices. Innovations in computer microarchitecture and accompanying compilers have enabled us to make...

Elementary Particles on a Dedicated Parallel Computer

Numerical simulation of lattice QCD is now an indispensable tool for investigating non-perturbative properties of quarks at low energies. In this paper, I introduce a recent lattice QCD calculation of light hadron spectrum and quark masses performed on a dedicated parallel computer, CP-PACS. From a simulation of QCD with two flavors of dynamical quarks, we find m MS ud (2GeV) = 3.44 +0.14 −0.22...

Movement Control: Dedicated or Distributed?

Neural networks in which 'commands' spread 'horizontally' across multiple neurons have been believed to mediate motor pattern variation. A recent study shows that dedicated 'vertical' neural pathways can also underlie these variations.
