ExaGeoStat: A High Performance Unified Software for Geostatistics on Manycore Systems
Sameh Abdulah, Hatem Ltaief, Ying Sun +2
We present ExaGeoStat, a high performance framework for geospatial statistics in climate and environment modeling. In contrast to simulation based on partial differential equations…
Batched QR and SVD Algorithms on GPUs with Applications in Hierarchical Matrix Compression
Wajih Halim Boukaram, George Turkiyyah, Hatem Ltaief +1
We present high performance implementations of the QR and the singular value decomposition of a batch of small matrices hosted on the GPU with applications in the compression of hi…
Accelerated Cyclic Reduction: A Distributed-Memory Fast Solver for Structured Linear Systems
Gustavo Chávez, George Turkiyyah, Stefano Zampini +2
We present Accelerated Cyclic Reduction (ACR), a distributed-memory fast direct solver for rank-compressible block tridiagonal linear systems arising from the discretization of ell…
