Fog networks have attracted the attention of researchers recently. The idea is that a part of
the computation of a job/application can be performed by fog devices that are located at the …

Next-generation systems face a wide range of new potential sources of application
interference, including resilience actions, system software adaptation, and in situ analytics …

The increase in scale and heterogeneity of high-performance computing (HPC) systems
predispose the performance of Message Passing Interface (MPI) collective communications …

We present a detailed examination of time agreement characteristics for nodes within
extreme‐scale parallel computers. Using a software tool we introduce in this paper, we …

Scientific workloads running on current extreme-scale systems routinely generate
tremendous volumes of data for postprocessing. This data movement has become a serious …

High-performance computing (HPC) systems keep growing in scale and heterogeneity to
satisfy the increasing need for computation, and this brings new challenges to the design of …

As high-performance computing systems continue to evolve on the way to exascale, the
performance heterogeneity of components in the system is increasing. This heterogeneity …

On current generation petascale supercomputers, large-scale science applications like GTC
[2] and S3D [34] are already stressing the limits of the capabilities these machines provide …
