From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jason Gunthorpe Subject: python-rdma v0.1 Release Announcement Date: Tue, 15 Mar 2011 12:02:03 -0600 Message-ID: <20110315180203.GD12991@obsidianresearch.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, EWG List-Id: linux-rdma@vger.kernel.org I am pleased to announce the initial release of `python-rdma` a package to provide a Python API for the Linux RDMA stack. This initial release is mainly focused on IB specific management APIs, but the package also covers ibverbs. A new API was developed for this library that is designed to take advantage of Python features and provides a very uniform, integrated design across all the different aspects of IB and RDMA programming. It has a particular focus on ease of use and correct operation of the IB and RDMA protocol stacks. Included is a re-implementation of a substantial portion of the `infinband-diags` package. This re-implementation is functionally very similar to `infiniband-diags` but also gains a number of new features: - Uniform end port addressing. All commands support GID, port GUID, LID and DR path, even commands that are GMP based (like perfquery). - Support for collecting information entirely from the SA via the `--sa` option. - Consistently fetches path records for GMP communication (eg in perfquery) to support topologies with special requirements. - Extensive MAD parallelization provides very good performance. - All commands support a discovery cache file, which stores information in an efficient binary format. - Much better debugging, including packet tracing down to full field decode. - Minor new features to many tools, review section 8 of the manual for details. The library itself is intended mainly for applications where quick development is more important that the highest performance, such as: - IB manamagent software development - RDMA test development - Training and problem exploration Although already quite complete there are a few obvious areas that I hope to have finished in the future: - Integration of IB and RDMA CMs - Support for RMPP when using verbs to issue GMPs - this will enable all diags to function in `--sa` mode without access to /dev/umad. - Completion of missing `infinband-diags` commands It is my hope this work will be of use to the wider InfiniBand community. Extensive prebuilt documentation for the module can be reviewed online , and the source code is available on GitHub . I'm planning to give a short presentation on this library at the forthcoming Monterey workshop, see you all there!
