Cilk (pronounced “silk”) is a C-based algorithmic, multithreaded language for parallel programming being developed at the MIT Laboratory for Computer Science. Cilk makes it easy to program irregular parallel applications, especially as compared with data-parallel or message-passing programming systems. Many regular and irregular Cilk applications run nearly as fast as comparable C programs on o...

1926 JOURNAL OF PHYSICAL OCEANOGRAPHY VOLUME 31 Reply

Hallberg (1997) used a combination of quasigeostrophic ray tracing and primitive equation numerical simulations to study the propagation of topographic and planetary Rossby waves around an ocean basin with slowly varying but arbitrary topography. When the topographic and planetary vorticity gradients are not parallel to each other, the classical baroclinic and barotropic modes are replaced by m...

How do ants assess food volume?

By comparing the behaviour of Lasius niger scouts at sucrose droplets of different volumes, we empirically identified the criterion used by each scout to assess the amount of food available as well as the rules governing its decision to lay a recruitment trail. When scouts discovered food volumes exceeding the capacity of their crop (3 or 6 µl), 90% immediately returned to the nest laying a rec...
