Read in parallel

[mattbellis]

h5py parallel.

There is already is read.py a way to read "chunks" of the data. For example from event 0 to 99.

Can we have an example with 4 threads (?) reading simultaneously from 0-99, 100-199, etc.?

I tried to do this with pythons built in multiprocessing.Pool function and it does not work because h5py File objects can not be pickled. The error can be recreated in this notebook.

I read through the h5py mpi docs link above and it seems like it needs some extra modules installed. I will look into those more and try to utilize them!
