New tools
- Mochi-json-vis
- https://github.com/mochi-hpc/mochi-json-vis
- A command-line tool that can be used to generate a visual representation of a Mochi Bedrock configuration.
- This can be helpful to sanity check or better understand service configuration details such as the mapping of providers to execution streams.
Software updates
- Mochi-thallium 0.10.1 (C++ bindings to Mochi)
- Adds support for timer_callback
- Adds logger class and logging functionality
- Adds access to margo’s underlying configuration, pools, and xstreams
- Mochi-bedrock 0.4.1 (service configuration framework)
- Ability to initialize the server with a JX9 script instead of a JSON configuration

Upcoming events
Building Custom Data Services with Mochi (public BoF)
May 12th, 11:00 AM eastern time
We will provide general updates on the Mochi project, highlight key capabilities related to service composition and key/value stores, and share work from guest speakers about the Mochi messaging layer and successful Mochi use cases:
- Mercury: platform updates and optimizations for RPC and RDMA communication (Jerome Soumagne, The HDF Group)
- Chimbuko: scalable application performance analysis and provenance (Chris Kelly, Brookhaven National Laboratory)
- DataSpaces: extreme-scale data management framework (Philip Davis, University of Utah)
