GASE: a high performance solver for the Generalized Nonlinear Schrödinger equation based on heterogeneous computing

European Regional Policy in the Nord -Pas-de-Calais. The Nord -Pas-de-Calais region benefits from rather considerable european funds. The eligibility of part of its territorry to objective 1 of the european regional policy brings new means to compensate for the delay in its development.Le Nord -Pas-de-Calais bénéficie de financements européens non négligeables. Notamment l'éligibilité d'une partie de son territoire à l'objectif 1 de la politique régionale européenne représente de nouveaux moyens au service du rattrapage de développement.Paris Didier.

Accelerating dissipative particle dynamics with multiple GPUs

Dissipative particle dynamics (DPD) simulation is implemented on multiple GPUs by using NVIDIA's Compute Unified Device Architecture (CUDA) in this paper. Data communication between each GPU is executed based on the POSIX thread. Compared with the single-GPU implementation, this implementation can provide faster computation speed and more storage space to perform simulations on a significant larger system. In benchmark, the performance of GPUs is compared with that of Material Studio running on a single CPU core. We can achieve more than 90x speedup by using three C2050 GPUs to perform simulations on an 80 * 80 * 80 system. This implementation is applied to the study on the dispersancy of lubricant succinimide dispersants. A series of simulations are performed on lubricant-soot-dispersant systems to study the impact factors including concentration and interaction with lubricant on the dispersancy, and the simulation results are agreed with the study in our present work.
