Scalable Resilience Against Node Failures for Communication-Hiding Preconditioned Conjugate Gradient and Conjugate Residual Methods
Markus Levonyak, Christina Pacher, Wilfried N. Gansterer
The observed and expected continued growth in the number of nodes in large-scale parallel computers gives rise to two major challenges: global communication operations are becoming…

How to Make the Preconditioned Conjugate Gradient Method Resilient Against Multiple Node Failures
Carlos Pachajoa, Markus Levonyak, Wilfried N. Gansterer +1
We study algorithmic approaches for recovering from the failure of several compute nodes in the parallel preconditioned conjugate gradient (PCG) solver on large-scale parallel comp…
