Ulysses of Embra

Fast Functional Simulation with Parallel Embra

A shift towards chip multiprocessor (CMP) designs has rekindled interest in full-system simulation of multiprocessors. Recent work has attempted to address the problem of linear (or worse) slowdown incurred during sequential simulation of a multiprocessor. Methods such as exploitation of the speed/detail trade-off, division (decimation) in simulation time, and statistical simulation share the c...

The Ulysses perspective

Current sheets from Ulysses observation

Current sheet is a significant source of solar wind MHD turbulence intermittency. It has long been recognized that these structures can arise from non-linear interactions of MHD turbulence. Alternatively, they may also be relic structures in the solar wind that have a solar origin, e.g., magnetic walls of flux tubes that separate solar wind plasma into distinct parcels. Identifying these struct...

Children's understanding of the Ulysses conflict.

Two studies explored children's understanding of how the presence of conflicting mental states in a single mind can lead people to act so as to subvert their own desires. Study 1 analyzed explanations by children (4--7 years) and adults of behaviors arising from this sort of 'Ulysses conflict' and compared them with their understanding of conflicting desires in different minds, as well as with ...

Diabetes, Muscles, and the Myth of Ulysses' Bow

A t the end of Homer's Odyssey, after 20 years of adventurous traveling, the goddess Athena brings Ulysses back to Ithaca disguised as an old man. With little hope for Ulysses' return, his faithful wife Penelope has reluctantly agreed to marry whoever wins a contest using Ul-ysses' bow. In spite of his infirmed appearance , Ulysses is the only contestant strong enough to string the bow and shoo...
