was particularly effective in HPC because clusters were composed of singe- or dual-processor (one- or two-core) nodes and a high-speed interconnect. The Message-Passing Interface (MPI) mapped efficiently onto ... HPC, parallel processing, GPU, multicore, OpenMP, MPI, many core, OpenACC, CUDA, MICs, GP-GPU

Hadoop version 2 expands Hadoop beyond MapReduce and opens the door to MPI applications operating on large parallel data stores. ... non-MapReduce algorithms has long been a goal of the Hadoop developers. Indeed, YARN now offers new processing frameworks, including MPI, as part of the Hadoop infrastructure. Please note that existing ... Hadoop version 2 expands Hadoop beyond MapReduce and opens the door to MPI applications operating on large parallel data stores.

improve application performance and the ability to run larger problems. The great thing about HDF5 is that, behind the scenes, it is performing MPI-IO. A great deal of time has been spent designing

of classic HPC tools, such as MPI for Python (mpi4py ), a Python binding to the Message Passing Interface (MPI). Tools such as Dask focus on keeping code Pythonic, and other tools support the best performance
