Algorithm-Based Checkpoint-Recovery for the Conjugate Gradient Method
Carlos Pachajoa, Christina Pacher, Markus Levonyak +1
As computers reach exascale and beyond, the incidence of faults will increase. Solutions to this problem are an active research topic. We focus on strategies to make the preconditi…

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…
