Dragonfly is a highly scalable, low-diameter, and cost-efficient network topology, which has
been adopted in new exascale High Performance Computing (HPC) systems. However …

Modern computing systems are highly affected by large performance variability, resulting in
a long tail in the distribution of the network latency. For communication-intensive …

As network speeds increase, the overhead of processing incoming messages is becoming
onerous enough that many manufacturers now provide network interface cards (NICs) with …

The development of new exascale supercomputers has dramatically increased the need for
fast, high-performance networking technology. Efficient network topologies, such as …

Distributed parallel MPI applications are the dominant workload in many high-performance
computing systems. While optimizing MPI application execution is a well-studied field, little …

In recent years, energy has become one of the most important factors for de-signing and
operating large scale computing systems. This is particularly true in high-performance …
