Traditional point-to-point communication sends data only after the entirety of the data is
available. This includes situations where multiple actors (eg, threads) contribute to the send …

This paper explores key differences of MPI match lists for several important United States
Department of Energy (DOE) applications and proxy applications. This understanding is …

Attaining high performance with MPI applications requires efficient message matching to
minimize message processing overheads and the latency these overheads introduce into …

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 …

Although its demise has been frequently predicted, the Message Passing Interface (MPI)
remains the dominant programming model for scientific applications running on high …

With the continual increase in the high performance computing (HPC) market share, the
need for a cheaper and widely available system rather than the expensive typical HPC …

While cloud computing is widely adopted in many application domains, it is not yet the case
for the high performance computing (HPC) domain. HPC traditionally runs on …

This paper describes work with end goal of quantifying the impact of threading on MPI
performance models in order to enable justifications of model construction methods. To do …

Understanding the performance of parallel and distributed programs remains a focal point in
determining how compute systems can be optimized to achieve exascale performance …

In prior work, a message-passing performance model was presented to evaluate specific
characteristics of network performance when two endpoints transmit simultaneously …
