CLIO is the agent layer of IOWarp, GRC's platform for managing scientific data and context for AI. In February 2026 it had two parts, a storage runtime and a tool kit. By November 13 it had six, each with its own release schedule, and together they had published more than 300 tagged releases on GitHub this year. This is a tour of what each part does and how it got there.
Between April 2 and November 12, the ChronoLog team published eleven releases, from 2.5.0 to 3.5.0. Over those seven months, GRC's distributed log store gained SQL, publish-subscribe and agent interfaces. It also learned to keep every event it acknowledges, even through a crash, and moved to a current HPC software stack. This is a summary of the year, release by release.
On August 5, 2024, the National Science Foundation awarded the collaborative Frameworks grant "IOWarp: Bending the I/O Fabric for Advancing AI-Infused Scientific Workflows". GRC leads the project, with the University of Utah as partner institution.
The National Science Foundation has awarded a collaborative CSSI Framework grant (OAC-2104013) for ChronoLog, a distributed and tiered logging system designed for exascale high-performance computing systems and large-scale data centers.
The National Science Foundation has awarded a Framework Grant (OAC-1835764) to Xian-He Sun for the Hermes project, a heterogeneous-aware multi-tiered distributed I/O buffering system designed to address the growing performance gap between computing power and storage systems.
