The hybrid MPI+ X programming paradigm, where X refers to threads or GPUs, has gained
prominence in the high-performance computing arena. This corresponds to a trend of …

Partitioned point-to-point communication primitives provide a performance-oriented
mechanism to support a hybrid parallel programming model and have been included in the …

MPI+ threads is gaining prominence as an alternative to the traditional" MPI everywhere"
model in order to better handle the disproportionate increase in the number of cores …

Partitioned point-to-point communication and persistent collective communication were both
recently standardized in MPI-4.0. Each offers performance and scalability advantages over …

Hybrid MPI+ threads programming is gaining prominence, but, in practice, applications
perform slower with it compared to the MPI everywhere model. The most critical challenge to …

The difficulty of deep experimentation with Message Passing Interface (MPI)
implementations—which are quite large and complex—substantially raises the cost and …

Asynchronous programming models (APM) are gaining more and more traction, allowing
applications to expose the available concurrency to a runtime system tasked with …

Modern communication APIs provide increased ability to specify when, where, and how to
send data between processes. One recent innovation is fine-grained communication, where …

Modern High-Performance Computing (HPC) architectures have developed the need for
scalable hybrid programming models. The latest Message Passing Interface (MPI) 4.0 …

Modern HPC systems require efficient hybrid programming model to utilize their hardware
resources effectively. The Message Passing Interface (MPI) has accommodated next …
