Mochi updates and agenda items

  • Upcoming publications:
    • Ankush Jain, Chuck Cranor, Qing Zheng, Brad Settlemyer, George Amvrosiadis, Gary Grider, “CARP: A Streaming Partitioner for Range Queries”, in Proceedings of the International Conference on High Performance Computing, Networking, Storage and Analysis 24 (2024).
  • Recent publications:
    • Matthieu Dorier, Philip Carns, Robert Ross, Shane Snyder, Rob Latham, Amal Gueroudji, George Amvrosiadis, Chuck Cranor, Jerome Soumagne, “Extending the Mochi Methodology to Enable Dynamic HPC Data Services,” in proceedings of the 5th Workshop on Extreme-Scale Storage and Analysis (ESSA 2024) May, 2024.
  • Software updates:
    • mochi-margo 0.17.0 was released in May 2024. This is the core RPC management component that ties together Mercury RPCs and Argobots user-level threads. The 0.17.0 release features a new margo_monitor_dump() function that can be used to emit (and optionally reset) integrated Margo monitoring data at runtime rather than waiting for program termination.
    • Mochi-flock 0.3.1 was released in July 2024. It is a new implementation of group membership functionality for Mochi services (replacing mochi-ssg). Recent release have added a variety of new features as well as a Python and C++ API.
    • Mochi-bedrock 0.13.1 was released in July 2024. It is a bootstrapping and configuration management component for Mochi services. Recent releases have added mochi-flock support (enabled by default), added support for TOML configurations, and split the module api out into a separate component called mochi-bedrock-module-api.
    • Mofka 0.1.1 was released in July 2024. Mofka is a new top-level Mochi service that implements a distributed event streaming model for HPC services. Mofka is still under active development but includes documentation and a stable API.
    • Mercury 2.4.0rc3 was released in June 2024. Mercury is the underlying RPC and bulk RDMA transfer framework used for communication in in Mochi. This preview release includes several new tuning parameters and a new API that enables users to wait on a file descriptor for new events. We plan to leverage this feature in Margo in the future to improve network polling efficiency.
