Physically Based Node Distributions For Mesh Generation

International Journal of Modelling and Simulation, 2008
A new physically based approach to mesh generation is proposed, which uses the variants of Monte-Carlo (MC) technique. The mesh nodes are treated as interacting particles and their positions are determined using energy minimization. When the approach is extended with the grand-canonical MC scheme the optimization is performed for both the number of ...

Physical design challenges beyond the 22nm node

Proceedings of the 19th international symposium on Physical design, 2010
Producing working chips in current (32nm) and forthcoming CMOS technologies feels a lot like trying to create an intricate oil painting using a broom! After all, we are using light with a wavelength of 193nm to create shapes less than a tenth of a wavelength in dimension.

Improving communication by optimizing on-node data movement with data layout

ACM SIGPLAN Symposium on Principles & Practice of Parallel Programming, 2021
We present optimizations to improve communication performance by reducing on-node data movement for a class of distributed memory applications. The primary concept is to eliminate the data movement associated with packing and unpacking subsets of the ...

Ocean Bottom Nodes Ultrasonic Physical Experiment

Proceedings, 2016
The current efforts in the hydrocarbon industry have been concentrating in maximize oil and gas production from existing fields as the task of find new reservoirs becomes expansive and difficult. Hence, converted-waves are used in partnership with P-waves for a more complete understanding of reservoirs’ properties and geometrical arrangement.
