Query: Exploiting Redundant Computation in Communication-Avoiding Algorithms
  for Algorithm-Based Fault Tolerance   Communication-avoiding algorithms allow redundant computations to minimize
the number of inter-process communications. In this paper, we propose to
exploit this redundancy for fault-tolerance purpose. We illustrate this idea
with QR factorization of tall and skinny matrices, and we evaluate the number
of failures our algorithm can tolerate under different semantics.
