如何设置LSF数组任务仅在任务失败时发送邮件？

Absolutely! You can adjust your LSF job submission parameters to only receive email notifications when an array task fails, instead of getting a notification for every completed task. Here's how to modify your configuration:

Modified BSUB Script #

#BSUB -J "myArray[1-50]"
#BSUB -o o.%J.%I
#BSUB -e e.%J.%I
#BSUB -W 10:00
#BSUB -notify "EXIT:!=0"  # Only trigger email on non-zero exit codes (failure)
#BSUB -u myEmail@somewhere.com

Key Changes Explained #

• Replace the original #BSUB -N with #BSUB -notify "EXIT:!=0":
  • The -notify parameter lets you specify exactly when LSF sends notifications.
  • EXIT:!=0 tells LSF to only send an email if a task exits with a non-zero exit code (which indicates a failure). Successful tasks (exit code 0) won't trigger any email.
• You keep all other parameters (-J, -o, -e, -W, -u) as they are—these handle the array job definition, output/error logging, runtime limit, and recipient email respectively.

Expected Outcome #

With this setup:

• You'll only receive emails for array tasks that fail (e.g., tasks 11, 12, 25 in your example).
• Each failure email will have a title like:

  Job 123456[11]: <myArray[1-50]> in cluster Exited

• Successful tasks won't send any notifications, so you won't get 50 emails when all jobs finish successfully.

Notes for Compatibility #

If your LSF version doesn't support the EXIT:!=0 conditional syntax (older versions might have limited -notify functionality), you can use a simpler approach:

1. Keep #BSUB -N but add a check in your job script to only generate error output on failure. However, this relies on your script correctly capturing failures.
2. Alternatively, check your cluster's LSF documentation for version-specific notification options.
