Has anyone had this error before? It seems somewhat random (i.e. hard to reproduce), but still happens often enough to be a nuisance. So far, it's happened while using NAMD 2.14 multicore CUDA 8/05/2020 version using nodes that each have either NVIDIA 2x2080ti or 2xTitanX gpus. I'm trying the same jobs on 2.13 right now to see if the same error occurs. Showed the person who manages our Linux cluster, but he hasn't seen this before and is looking into it. In the meantime, I'm checking here too. Thanks!
