During MPI_Init, all of MPI's global and internal variables are constructed. For example, a communicator is formed around all of the processes that were spawned, and unique ranks are assigned to each ...

Hi guys! Either you are a Computer Science student, or just a brave programmer who wants to start learning the basic of parallel programming in shared and/or distributed memory systems, this ...

Modern high-performance networks offer remote direct memory access (RDMA) that exposes a process’ virtual address space to other processes in the network. The Message Passing Interface (MPI) ...

Abstract: This work assesses the viability of different programming models for large-scale manycores using an MPI-like abstraction, the vendor's OpenMP, and a combination (hybrid) of both. Experiments ...

Abstract: The efficient development of parallel applications is challenging despite the availability of various tools and libraries that help specify communication and synchronization among other ...

I've been covering various scientific programs the past few months, but sometimes it's hard to find a package that does what you need. In those cases, you need to go ahead and write your own code.
