所以一种思路增加程序效率线性的方法是用MPI/OPENMP混合编写并行部分。这一部分其实在了解了MPI和OPENMP以后相对容易解决点。大致思路是每个节点分配1-2个MPI进程后,每个MPI进程执行多个OPENMP线程。OPENMP部分由于不需要进程间通信,直接通过内存共享方式交换信息,不走网络带宽,所以可以显著减少程序所需通讯的信息。 Fortran...
The chapter introduces hybrid MPI-OpenMP parallel computation to keep simple code and to reduce calculation time in the condition. This parallel method is good candidate to treat more complicated fluids with thermal. The particle-based models are popular scheme for fluid flow analysis based on micro...

We present hybrid OpenMP/MPI (Open Multi-Processing/Message Passing Interface) parallelized versions of earlier published C programs (Vudragović et al. 2012) for calculating both stationary and non-stationary solutions of the time-dependent Gross–Pitaevskii (GP) equation in three spatial dimensions...
