The ACM SIGOPS Annual Technical Conference (formerly the USENIX Annual Technical Conference), or ATC for short, is an academic conference focused on systems research. It is sponsored by ACM SIGOPS, the Special Interest Group on Operating Systems. Between 1975 and 2025, ATC was sponsored by USENIX and constituted its flagship conference; for much of this period, it was referred to simply as "USENIX." After 50 years of activity, USENIX decided to sunset ATC, but SIGOPS stepped in to continue the conference in response to a community petition.
