Computes the optimal chunk dimensions for consecutive row/column access from a HDF5Matrix.
An integer vector of length 2 containing the dimensions of a HDF5Matrix object.
Consider a HDF5Matrix where access to consecutive rows or columns is requested. The optimal chunk dimensions ensure that the number of disk reads required is the same as that of a file layout with pure row or column chunks. This exploits the HDF5 chunk cache to store data from neighbouring rows/columns, avoiding the need to reread or rewrite the entire chunk for the next row/column. Obviously, this is not relevant to situations involving random row or column access.
An integer vector of length 2, containing the dimensions of each chunk in the HDF5 file.
