Optimizing the Cost and Performance for Batch jobs on HPC by Utilizing Swap Space

High Performance Computing (HPC) facilities play a crucial role in acceler- ating Electronic Design Automation (EDA) procedures at NXP Semiconduct- ors. The increasing number of job requests and workloads has led to a surge in memory demand, which is a costly resource. To address this, we leverage memory swap space on disk as a more affordable...

Building Design Approaches and Performance Under Predicted Climate Conditions

The building environment has high energy consumption and carbon emission which contributes to the rapid climate change. The changing climate condition not only impacts the natural environment but also our habitation. To improve the building performance in both energy and indoor comfort, performance-based design is commonly applied in...

Optimizing SGLR Parser Performance

The Scannerless Generalized-LR (SGLR) parsing algorithm allows parsing of declarative and modular syntax definitions. However, SGLR is notorious for having low performance, negatively impacting its adoption in practice. This paper presents several performance optimizations for JSGLR2, which is an implementation of SGLR. All optimizations are...

A computational method to guide sustainable energy upgrading of school buildings in Greece through passive design interventions

A big part of the schools in Greece fails to align with the regulations suggested by The School Building Organization in Greece, regarding their energy performance as well as the thermal and daylight comfort they offer. This study aims to inform the retrofit process of these schools, by proposing guidelines concerning the most impactful...

Design parameter guidelines for purely passive cooling buildings in Tropical regions

Nowadays, the energy consumption has a significant role in the entire life cycle of a building.
