On solving sparse linear systems in a distributed computing environment, Li notes, “The team also improved the asynchronous algorithm in [a] parallel triangular solve using [a] 3D MPI process ...

The two-sided Lanczos algorithm sometimes suffers from serious breakdowns. These occur when the associated moment matrix does not permit triangular factorization. We modify the algorithm slightly so ...
