I'm not too interested in tuning on this system right now because for my current code I/O time is significantly less than simulation time. However, I am using multiple compute nodes. If I open up an H5 file with serial HDF5, can I write the metadata with one node (setup groups/attributes/datasets), and then later open up the H5 file from multiple nodes and only write actual data? -- Andrew Ho
