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

Reaching Exascale will require leveraging massive parallelism while potentially leveraging
asynchronous communication to help achieve scalability at such large levels of concurrency …

As we approach exascale, computational parallelism will have to drastically increase in
order to meet throughput targets. Many‐core architectures have exacerbated this problem by …

This paper presents PAMPAR, a new benchmark to evaluate the performance and energy
consumption of different Parallel Programming Interfaces (PPIs). The benchmark is …

The Message Passing Interface (MPI) standard allows user-level threads to concurrently call
into an MPI library. While this feature is currently rarely used, there is considerable interest …

This paper presents a fine-grain queueing model of MPI point-to-point messaging
performance for use in the design and analysis of current and future large-scale computing …

OpenSHMEM is a popular one-sided communication library for high-performance computing
systems developed around 2010 at the University of Houston [2]. It is becoming an …
