LC/DC: Lockless Containers and Data Concurrency a Novel Nonblocking Container Library for Multicore Applications

Exploiting the parallelism in multiprocessor systems is a major challenge in modern computer science.Multicore programming demands a change in the way we design and use fundamental data structures.The standard collection of data structures and algorithms in C++11 is the sequential standard template library (STL).In this paper, we present their visi

The effects of flame orientation and mean shear on flame stretch in highly turbulent premixed flames using DNS

In the present work, direct numerical simulation data of a laboratory-scale high Karlovitz number (Ka) jet flame with a strong mean shear and a high Ka freely propagating planar flame without a mean shear were analyzed to explore the influence of flame orientation and mean shear on flame stretch in highly turbulent flames.Three flame fronts, i.e.th
