A QDWH-based SVD Software Framework on Distributed-memory Manycore Systems

The authors would like to thank Jack Poulson from Google Inc. for his help in tuning Elemental and the vendor Cray for systems' remote accesses in the context of the Cray Center of Excellence awarded to the Extreme Computing Research Center at KAUST. The authors would like also to thank Mohammad Hadi and Nick Hill from Cray for their help integrating QDWH-based SVD solver into Cray LibSci library. For computer time, this research used the resources from KAUST Supercomputing Laboratory for Shaheen-2 core hour allocations.
