Parallel algorithms can be hard to write, and even harder to debug. Testing, though essential, is insufficient, as fatal race conditions can have extremely low probabilities of occurrence. Proofs of ...

Researchers report distributed-memory implementations of the WCC and CM algorithms that post-process network clusterings for ...

One of the goals in high-performance computing (HPC) is to achieve the best possible performance from parallel computers. But performance can be measured in a variety of ways; in HPC, we are generally ...
