Testing a scalability bottleneck requires a large system to generate sufficient load, which is
usually not accessible to researchers. To address this problem, this paper extrapolates the …

Increasing number of MPI applications are being ported to take advantage of the compute
power offered by GPUs. Data movement on GPU clusters continues to be the major …

We investigate the dynamics of monitored memory resource utilizations in an operating
system under stress using quantitative methods of fractal analysis. In the experiments, we …

The integrated architecture that features both CPU and GPU on the same die is an emerging
and promising architecture for fine-grained CPU-GPU collaboration. However, the …

This paper addresses the challenges of MPI derived datatype processing and proposes
FALCON-X—A Fast and Low-overhead Communication framework for optimized zero-copy …

Noncontiguous data communication has been heavily adopted in scientific applications,
especially for those written with MPI. Common strategies to handle noncontiguous data, like …

In the last decade, many scientific applications have been significantly accelerated by large-
scale GPU systems. However, the movement of non-contiguous GPU-resident data is one of …

In data management systems, query processing on GPUs or distributed clusters have
proven to be an effective method for high efficiency. However, the high PCIe data transfer …

The recent advent of the NVLink interconnect and Peripheral Component Interconnect
express (PCIe) switch has resulted in the creation of extremely dense Graphics Processing …

The importance of GPUs in accelerating HPC applications is evident by the fact that a large
number of super-computing clusters are GPU-enabled. Many of these HPC applications use …
