CERN's IT systems passed a major stress test simulating the HL-LHC's 2030 data load, handling 16,800 jobs per minute with high efficiency.
CERN’s IT teams successfully completed a major stress test in October 2025, simulating the extreme workloads expected from the High-Luminosity LHC (HL-LHC) starting in 2030.
The test handled over two million tasks across 13 hours, processing about 16,800 jobs per minute—20 times the current average—while maintaining an average job handling time of five minutes.
Using HTCondor software, the system demonstrated strong resilience under heavy load, a critical step in preparing for the HL-LHC’s projected data output of up to 300 inverse femtobarns per year.
Additional tests on data storage systems are planned to ensure full readiness.
