A distributed-memory hierarchical solver for general sparse linear systems

•Derived a new formulation of a sequential hierarchical solver, which compresses dense fill-in blocks.•Proposed a new parallel algorithm for solving general sparse linear systems based on data decomposition.•Implemented a task-based asynchronous scheme by exploiting data dependency in our algorithm....
