I wrote a script calling qsub and getting the the job id back using pipe, but it won't work. It seems qsub won't flush the standard output until the job finished.
Here's the code I wrote for testing:
open (TEST, "qsub -sync yes sleep.sh |");
Only when the job finishes, the job number will be printed out, together with the exit information:
Your job 284190 ("sleep.sh") has been submitted
Job 284190 exited with exit code 0.
I also wrote a DRMAA version of qsub_perl, using perl DRMAA binding. In the script I add "$|=1". Then I use the above script to call my qsub_perl, I can successfully get the job number.
Can anyone give me some suggestion? Thanks.
