Due to the emergence of AMD GPUs and their adoption in upcoming exascale systems (e.g. Frontier), it is pertinent to have scientific applications and communication middlewares ported and optimized for these systems. Radeon Open Compute (ROCm) platfor

The Message-Passing Interface (MPI) is the de-facto standard for designing and executing applications on massively parallel hardware. MPI collectives provide a convenient abstraction for multiple processes/threads to communicate with one another. Mel

MPI implementations are becoming increasingly complex and highly tunable, and thus scalability limitations can come from numerous sources. The MPI Tools Interface (MPI_T) introduced as part of the MPI 3.0 standard provides an opportunity for performa

An efficient implementation of the Process Management Interface (PMI) is crucial to enable fast start-up of MPI jobs. We propose three extensions to the PMI specification: 1) a blocking all gather collective (PMIX_Allgather), 2) a non-blocking all ga

An efficient implementation of the Process Management Interface (PMI) is crucial to enable a scalable startup of MPI jobs. We propose three extensions to the PMI specification: a ring exchange collective, a broadcast hint to Put, and an enhanced Get.

As InfiniBand (IB) clusters grow in size and scale, predicting the behavior of the IB network in terms of link usage and performance becomes an increasingly challenging task. There currently exists no open source tool that allows users to dynamically

The upcoming MPI-3.0 standard is expected to include non-blocking collective operations. Non-blocking collectives offer a new MPI interface, using which an application can decouple the initiation and completion of collective operations. However, to b
