WebFor example, Hive will be moving to Spark, allowing an easy migration path for existing users; GraphX is based on the Pregel model of vertex-centric graph computation, but other graph libraries that leverage gather, apply, scatter (GAS) style computations could easily be implemented with RDDs. Gather/scatter is a type of memory addressing that at once collects (gathers) from, or stores (scatters) data to, multiple, arbitrary indices. Examples of its use include sparse linear algebra operations, sorting algorithms, fast Fourier transforms, and some computational graph theory problems. It is the vector equivalent of register indirect addressing, with gather involving indexed reads, and scatter, indexed writes. Vector processors (and some SIMD units in CPUs) have hardw…

WebMPI_Gather is the inverse of MPI_Scatter. Instead of spreading elements from one process to many processes, MPI_Gather takes elements from many processes and gathers them to one single process. This routine is highly useful to many parallel algorithms, such as parallel sorting and searching. Below is a simple illustration of this algorithm. WebAlternative Meanings.
