Same computer, same hardware, same OS, same executable, same input. None of the other 100 nodes in the cluster had that problem. A hardware issue for sure. | |

From my experience, the software on two computes is never really "identical", and errors can arise from all sorts of things, even tiny variations in the version or configuration of the operating system. | |

About hardware errors, I believe you are referring to the posets of up to 16 points. Fortunately, that case does not qualify here, because you caught the errors before publication. | |
