Multicore-optimized wavefront diamond blocking for optimizing stencil updates
Tareq Malas, Georg Hager, Hatem Ltaief +3
The importance of stencil-based algorithms in computational science has focused attention on optimized parallel implementations for multilevel cache-based processors. Temporal bloc…
Communication Complexity of the Fast Multipole Method and its Algebraic Variants
Rio Yokota, George Turkiyyah, David Keyes
A combination of hierarchical tree-like data structures and data access patterns from fast multipole methods and hierarchical low-rank approximation of linear operators from H-matr…
Asynchronous Execution of the Fast Multipole Method Using Charm++
Mustafa AbdulJabbar, Rio Yokota, David Keyes
Fast multipole methods (FMM) on distributed mem- ory have traditionally used a bulk-synchronous model of com- municating the local essential tree (LET) and overlapping it with comp…
A Performance Model for the Communication in Fast Multipole Methods on HPC Platforms
Huda Ibeid, Rio Yokota, David Keyes
Exascale systems are predicted to have approximately one billion cores, assuming Gigahertz cores. Limitations on affordable network topologies for distributed memory systems of suc…
