Quarterly Newsletter, January 2024

The Mochi quarterly meeting for Thursday, January 25, 2024 has been cancelled. Please reach out to us on the mailing list or Slack space if you have anything that you would like to discuss with the Mochi team. Otherwise we hope to see you at our next quarterly meeting on April 25.

Mochi quarterly meetings are a great opportunity to learn about community activities, share best practices, get help with problems, and find out what’s new in Mochi.

Please suggest agenda items on the Mochi slack space or the [email protected] mailing list.

Mochi updates

  • Software updates
    • Mofka version 0.0.2 was released on January 19, 2024. Mofka is a distributed event streaming service with semantics and data models similar to that of Kafka, but geared towards scientific computing on HPC platforms. It is still in an early alpha stage but we invite questions, feedback, and comments. We will cover Mofka in more detail in a future meeting.
    • Mercury version 2.3.1 was released on October 2.3.1. Mercury is the RPC framework used by Mochi for all communication and data transfer. This point release includes a collection of bug fixes and optimizations as well as support for more Slingshot VNI configurations.
  • Platform updates
    • The Mochi team is now using the ALCF Gitlab CI infrastructure to execute nightly performance regression tests on the Polaris system at the ALCF. We hope to expand this testing in the future. For now its primary objective is to monitor Slingshot network performance across not only Mochi updates but also HPE system software updates.
