Abstract
We present convergence results in expectation for stochastic subspace correction schemes and their accelerated versions to solve symmetric positive-definite variational problems, and discuss their potential for achieving fault tolerance in an unreliable compute network. We employ an overlapping domain decomposition algorithm for PDE discretizations to discuss the latter aspect.
