Viewing reserved memory for pending jobs (bjobs)

About this task

If the job memory requirements cannot be satisfied, bjobs -l shows the pending reason. bjobs -l shows both reserved slots and reserved memory.

Procedure

For example, the following job reserves 60 MB of memory on hostA:

bsub -m hostA -n 2 -q reservation -R"rusage[mem=60]" sleep 8888
Job <3> is submitted to queue <reservation>.

bjobs -l shows the reserved memory:

bjobs -lp
Job <3>, User <user1>, Project <default>, Status <PEND>, Queue <reservation>
                      , Command <sleep 8888>
