We present a sorting algorithm that works in-place, executes in parallel, is cache-optimal, avoids branch-mispredictions, and performs work O(n logn) for arbitrary inputs with high probability. We ran extensive experiments and show that our algorithm scales linearly in the number of cores on various multi-socket machines with 32 cores. On large inputs, we outperform our closest inplace competit...

The sunspot solar cycle has been usually explained as the result of a dynamo process operating in the sun. This is a classical problem in Astrophysics that until the present is not fully solved. Here we discuss current problems and limitations with the solar dynamo modeling and their possible solutions using the kinematic dynamo model with the Babcock-Leighton approximation as a tool. In partic...

We develop a model of the solar dynamo in which, on the one hand, we follow the Babcock–Leighton approach to include surface processes like the production of poloidal field from the decay of active regions, and, on the other hand, we attempt to develop a mean field theory that can be studied in quantitative detail. One of the main challenges in developing such models is to treat the buoyant ris...

Context. The turbulent pumping effect corresponds to the transport of magnetic flux due to the presence of density and turbulence gradients in convectively unstable layers. In the induction equation it appears as an advective term and for this reason it is expected to be important in the solar and stellar dynamo processes. Aims. In this work, we have explored the effects of the turbulent pumpin...
