history
Project history and usage
ClassAds are HTCondor's classified advertisement language and matching mechanism for describing jobs, machines, submitters, resources, and constraints in high-throughput computing systems.
Project history
The official ClassAds page describes ClassAds as the lingua franca of HTCondor, exchanged by HTCondor processes to describe jobs, workstations, and other resources. The same page states that the ClassAd library is also available as a standalone package outside HTCondor.
HTCondor documentation records a transition from Old ClassAds to New ClassAds: Old ClassAds were tied to HTCondor development libraries, New ClassAds added features and were designed as a standalone library, and HTCondor switched to the New ClassAd library in version 7.5.1.
Adoption history
The standalone C++ ClassAd distribution has official release history from 0.9.6 in October 2004 through 1.0.10 in April 2011. Homebrew packages that standalone tarball as classads 1.0.10 and reported 101 installs over the prior 365 days.
How it is used
ClassAds are used for matchmaking: a job ClassAd and a machine ClassAd can refer to one another while expressions evaluate whether constraints are satisfied. The Homebrew package exposes small C++ library utilities such as cxi and classad_version.
Why package nerds care
ClassAds is package-nerd interesting because Homebrew preserves a standalone slice of HTCondor's scheduler expression language as a small C++ package, separate from the much larger HTCondor system.
