Summary | 0015942: make PXML polydata and unstructured grid writers only write out needed files | ||||||||
Description | When using the PXML polydata and unstructured grid writers in parallel they all write a file even if there's no information stored in the file (e.g. the grid has no points). Additionally process 0 includes all of these files instead of just the files with data in them. This is a waste of IO. It would be useful to have an option such that the processes let process 0 know if they will be writing out data (i.e. check if they have any points) and notify process 0 if this is going to be done. Then when process 0 writes the meta-data file (.pvtp or .pvtu) it needs to exclude the data files that won't be written from being included in the meta-data file. This probably needs to be an option since I think the P in PXML really stands for piece and not necessarily parallel and I'm not sure if it's being used for pieces that it can properly be done (e.g. 8 pieces over 3 MPI processes). If it can be done for all use cases though it should just be done and ignore the option to do that. | ||||||||
