Selection consistency between distributed and local h5py?

[vjcitn]

Working with the tall data distributed with h5pyd, a simple selection generates invalid point argument error; below, the same operation succeeds with local hdf5 resource. Is there a reference on essential discrepancies between the two approaches?

I've checked in a fix for the point selection problem: https://github.com/HDFGroup/h5pyd/commit/db6522432e70fdc12c18a69cd598b8f62ee8e9bc. Let me know if that works for you.

In general the goal is for h5pyd to be completely compatible with the h5py high-level api.

There are some features that are not yet supported in h5serv, hence won't work for h5pyd. e.g.:

• field selection
• opaque types

And some features that work in h5serv, but have not yet been implemented in h5pyd, like region references.

And some things that don't work just because they are bugs!
Please file issues as you run across incompatibilities, and we'll address as soon as we can.

Oops, looks like there is a problem with the travis build: https://travis-ci.org/HDFGroup/h5pyd/jobs/219155977. I'll look into this.

Travis build is passing - closing.
