TeaMPI -- Replication-based Resilience without the (Performance) Pain
Philipp Samfass, Tobias Weinzierl, Benjamin Hazelwood +1
In an era where we can not afford to checkpoint frequently, replication is a generic way forward to construct numerical simulations that can continue to run even if hardware parts…
Coloured and task-based stencil codes
Benjamin Hazelwood, Tobias Weinzierl
Simple stencil codes are and remain an important building block in scientific computing. On shared memory nodes, they are traditionally parallelised through colouring or (recursive…
Studies on the energy and deep memory behaviour of a cache-oblivious, task-based hyperbolic PDE solver
Dominic E. Charrier, Benjamin Hazelwood, Ekaterina Tutlyaeva +5
We study the performance behaviour of a seismic simulation using the ExaHyPE engine with a specific focus on memory characteristics and energy needs. ExaHyPE combines dynamically a…
