Algorithmic patterns for $\mathcal{H}$-matrices on many-core processors
In this work, we consider the reformulation of hierarchical (H) matrix algorithms for many-core processors with a model implementation on graphics processing units (GPUs). H matrices approximate specific dense matrices, e.g., from discretized integral equations or kernel ridge regression, leading to log-linear time complexity in dense matrix-vector products. The parallelization of H matrix oper...

متن کاملBenchmarking Parallel Performance on Many-Core Processors
With the emergence of many-core processor architectures onto the HPC scene, concerns arise regarding the performance and productivity of numerous existing parallel-programming tools, models, and languages. As these devices begin augmenting conventional distributed cluster systems in an evolving age of heterogeneous supercomputing, proper evaluation and profiling of many-core processors must occ...
متن کاملThermal Field Management for Many-core Processors
This paper first presents an analysis of the global thermal field in many core processors in deep nanometer (to 16nm) nodes under power and thermal budget. We show that the thermal field can have significant spatiotemporal non-uniformity along with high maximum temperature. We propose spatiotemporal power multiplexing as a proactive method to reduce spatial and temporal temperature gradients. S...
متن کاملOperator frame for $End_{mathcal{A}}^{ast}(mathcal{H})$
Frames generalize orthonormal bases and allow representation of all the elements of the space. Frames play significant role in signal and image processing, which leads to many applications in informatics, engineering, medicine, and probability. In this paper, we introduce the concepts of operator frame for the space $End_{mathcal{A}}^{ast}(mathcal{H})$ of all adjointable operator...
