Say I submit a job using something like bsub pwd
. Now I would like to get the job ID of that job in order to build a dependency for the next job. Is there some
Just as a reference, this is the best solution I could come up with so far. It takes advantage of the fact that bsub write a line containing the ID to STDOUT.
function nk_jobid {
output=$($*)
echo $output | head -n1 | cut -d'<' -f2 | cut -d'>' -f1
}
Usage:
jobid=$(nk_jobid bsub pwd)
In case you are using C++, you can use the lsblib, LSF C API to submit jobs. The input and the output are structs. In particular, the output struct contains the job id.
#include <lsf/lsbatch.h>
LS_LONG_INT lsb_submit (struct submit *jobSubReq, struct submitReply *jobSubReply)
If you just want to view the JOBID after submission, most of the time I will just use bhist or bhist -l to view the running jobs and details.
$ bhist
Summary of time in seconds spent in various states:
JOBID USER JOB_NAME PEND PSUSP RUN USUSP SSUSP UNKWN TOTAL

Nils and Andrey have the answers to this specific question in shell and C/C++ environments respectively. For the purposes of building dependencies, you can also name your job with -J then build the dependency based on the job name:
bsub -J "job1" <cmd1>
bsub -J "job2" <cmd2>
bsub -w "done(job1) && done(job2)" <cmd>
There's a bit more info here.
This also works with job arrays:
bsub -J "ArrayA[1-10]" <cmd1>
bsub -J "ArrayB[1-10]" <cmd2>
bsub -w "done(ArrayA[3]) && done(ArrayB[5])" <cmd>
You can even do element-by-element dependency. The following job's i-th element will only run when the corresponding element in ArrayB
reaches DONE
status:
bsub -w "done(ArrayB[*])" -J "ArrayC[1-10]" <cmd3>
You can find more info on the various things you can specify in -w
here.
$jobid = "0"
bsub pwd > $jobid
cat $jobid
