| Release: 1.1 | Build date: Mon Dec 2 13:21:40 2024 |
| Group: System/Benchmark | Build host: reproducible |
| Size: 5360954 | Source RPM: stress-ng-0.18.07-1.1.src.rpm |

| Summary: Tool to load and stress a computer | |
stress-ng can stress various subsystems of a computer. It can stress load CPU, cache, disk, memory, socket and pipe I/O, scheduling and much more. stress-ng is a re-write of the original stress tool by Amos Waterland but has many additional features such as specifying the number of bogo operations to run, execution metrics, a stress verification on memory and compute operations and considerably more stress mechanisms.
