Benchmarking mixed-mode PETSc performance on high-performance architectures
Michael Lange, Gerard Gorman, Michele Weiland +3
The trend towards highly parallel multi-processing is ubiquitous in all modern computer architectures, ranging from handheld devices to large-scale HPC systems; yet many applicatio…
Achieving Efficient Strong Scaling with PETSc using Hybrid MPI/OpenMP Optimisation
Michael Lange, Gerard Gorman, Michele Weiland +2
The increasing number of processing elements and decreas- ing memory to core ratio in modern high-performance platforms makes efficient strong scaling a key requirement for numeric…
Mixed-mode implementation of PETSc for scalable linear algebra on multi-core processors
Michele Weiland, Lawrence Mitchell, Gerard Gorman +3
With multi-core processors a ubiquitous building block of modern supercomputers, it is now past time to enable applications to embrace these developments in processor design. To ac…
