BlockMGARD: Accelerating Adaptive Scientific Data Reduction with Region-of-Interest Error Control on GPUs

BlockMGARD is proposed, an adaptive, Region-of-Interest (ROI)-supported GPU lossy compressor, with four contributions: an In-cache Block decomposition leveraging GPU on-chip memory and constant lookup tables to accelerate decomposition; a hybrid hierarchy combining In-cache Block and global decomposition to balance spe...

Improving Progressive Compression with Adaptive Interpolation and Coefficient Decomposition

This work presents an adaptive progressive compression framework that improves retrieval efficiency for two common targets, namely error-bound and peak Signal-to-Noise ratios and proposes coefficient decomposition, a novel method that exploits the commonly overlooked spatial correlations among decorrelated data.
