There are thousands of datasets, and each datasets is about 200M, I want to read parts of data from each datasets.According to your experiences, which is better the following two methods? (Non parellel)
Method1. Open a dataset, and read, and close the datasets, and then open the next dataset, read, and close.
Method2. Open all the datasets, read , close all?
Or any other good features of HDF5 can achieve this?
Thanks in advance.
