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.
GRC released ChronoLog 1.0.0 (opens in a new tab) on June 6, 2024. It is the first public beta of ChronoLog, a distributed log store that GRC develops with the University of Chicago under an NSF CSSI framework grant. The release includes the three server components, a C++ client library with Python bindings, and example workloads. The team is asking users for feedback.
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.
