Hello, Looking at this task, it looks like the math is incorrect for the running time compare to the CPU time. Am I wrong ? task # 205157863 |

No, you are correct. Stderr output says THREADS=2 so CPU time should be slightly less than 2 X (run time). The CPU time is appropriate for an 8 thread task. I have seen this too on a few of my tasks. I think maybe it happens if I alter the nthreads argument in app_config.xml after the task downloads? For example, --nthreads=8 when the task downloads but after it downloads and before it runs --nthreads=2. |
