Petroleum geoscience big data is defined in this paper. CPU/GPU hybrid system is used to try to accelerate computing speed of petroleum geoscience big data using chaotic quantum particle swarm optimization (CQPSO) inversion method as an example, and…
Smart Grid Technology is an important part of increasing resilience and reliability of power grids. Applying Phasor Measurement Units (PMUs) to obtain synchronized phasor measurements, or synchrophasors, provides more detailed, higher fidelity data…
Efficient checkpointing of distributed data structures periodically at key moments during runtime is a recurring fundamental pattern in a large number of uses cases: fault tolerance based on checkpoint-restart, in-situ or post-analytics,…
Sparse triangular solves (SpTRSVs) are widely used in linear algebra domains, and several GPU-based SpTRSV algorithms have been developed. Synchronization-free SpTRSVs, due to their short preprocessing time and high performance, are currently the…
Matrix factorization on sparse matrices has been proven to be an effective approach for data mining and machine learning. However, the prior parallel implementations for matrix factorization fail to capture the internal social property embedded in…
Q-compensated reverse-time migration ( Q-RTM) has been proven as an efficient method for seismic imaging with high fidelity. However, the source (forward) and receiver (backward) wavefields propagate along the opposite direction of time, and the…
This paper describes a new scheme of a gas pumping unit (GPU). The proposed scheme will use an absorption heat transformer (AHT) to increase the energy efficiency of the gas pumping unit (GPU) using the waste heat of exhaust gases. The absorption…
