Load Balancing Scientific Applications
… must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load …

Energy-efficient strategies with base station power management for green wireless networks
… is to improve the energy efficiency and load balance for wireless networks. We first study the relationships between the base station (BS) on/off operation and traffic distribution. A cooperative power saving method called clustering BS-off (CBSO) scheme is proposed. Instead of adopting a …

A hybrid static/dynamic approach to scheduling stream programs
… Static scheduling may also incorrectly load-balance cores due to inaccurate static work estimates. This thesis contributes a hybrid static/dynamic scheduling approach that attempts to address the limitations of static scheduling. Dynamic load-balancing is utilized to adjust the static …

Towards Data-Driven I/O Load Balancing in Extreme-Scale Storage Systems
… high performance computing (HPC) centers exhibit load imbalance and resource contention. This is mainly due to two factors: the bursty nature of the I/O of scientific applications; and the complex and distributed I/O path without centralized arbitration and control. For example, the extant Lustre …

Techniques to maximize memory bandwidth on the Rigel compute accelerator
… serialization of conditional execution paths and load imbalance from varying task lengths. These benefits to the execution hardware come at a cost of reduced memory bandwidth, however, as it is difficult or impossible to orchestrate the memory requests in a way that achieves perfect access …
