DOI: 10.1109/lca.2020.3040326
Abstract: As transistor dimensions continue to shrink, long-term reliability threats, such as Negative Bias Temperature Instability, affect multicore processors lifespan. This letter proposes a load balancing technique, based on the rate of integer and floating-point instructions… read more here.

DOI: 10.1109/tc.2016.2605682
Abstract: One of the important characteristics of emerging multicores/manycores is the existence of “shared on-chip caches,” through which different threads/processes can share data (help each other) or displace each other’s data (hurt each other). Most of… read more here.

DOI: 10.1109/tcad.2022.3143476
Abstract: As the complexity of the multicore system grows, the large workload diversity results in serious thermal problems. In a practical way, the number of placed thermal sensors is usually limited due to the manufacturing cost.… read more here.

DOI: 10.1109/tpds.2016.2608824
Abstract: Modern homogeneous parallel platforms are composed of tightly integrated multicore CPUs. This tight integration has resulted in the cores contending for various shared on-chip resources such as Last Level Cache (LLC) and interconnect, leading to… read more here.

DOI: 10.1364/oe.410614
Abstract: In this work we analyze the power scaling potential of amplifying multicore fibers (MCFs) used in coherently combined systems. In particular, in this study we exemplarily consider rod-type MCFs with 2 × 2 up to 10 × 10 ytterbium-doped… read more here.
