python interface updates and balancing option
The first two commits are updates to the (new) python interface:
- allow setting the mismatch behavior (redistribute, allowed, disallowed) for more fine-grained control
- update dependencies (pybind11 to version 2.6.1)
The third commit is a function in
GenericIO:rebalanceSourceRanks that I originally wrote upon a request by Patricia. It is useful if the ranks that wrote the file were very unbalanced, which can happen for some analysis output.
- The function redistributes the storage-ranks such that each reading-rank has a similar amount of data to read.
- The reading can be faster or slower, depending on the machine and data.
- The function only has an effect if MPI is being used and
- The function needs to be manually called after
In case we don't want the last commit in the main branch, I can re-submit the merge-request with the first two commits only. However, since the rebalancing function only has an effect if manually called, it will not break/change any existing behavior.
