Reply To: Example issues on Cluster
Yes, amongst many other new features and improvements OpenLB 1.5 will include support for Nvidia GPUs in addition to vectorization on CPUs.
As for the checkpointing issue I suspect that the process config / assignment of blocks to processes is not the same between runs. Unfortunately this is a restriction of OpenLB’s current serialization system but in any case it should not segfault (and doesn’t when I just tested it using the pre-release version). Can you save and load a snapshot during the same HPC job to confirm that this is the issue?
