Running Parallel Jobs
Examples
% bsub -n 4 -R "span[hosts=1]" myjob
Runs the job on a host that has at least 4 processors currently eligible to run
the 4 components of this job.
% bsub -n 4 -R "span[ptile=2]" myjob
Runs the job on 2 hosts, using 2 processors on each host. Each host may have
more than 2 processors available.
% bsub -n 4 -R "span[ptile=3]" myjob
Runs the job on 2 hosts, using 3 processors on the first host and 1 processor
on the second host.
% bsub -n 4 -R "span[ptile=1]" myjob
Runs the job on 4 hosts, even though some of the 4 hosts may have more than
one processor currently available.
% bsub -n 4 -R "type==any same[type] span[ptile='!',LINUX:2, SGI:4]" myjob
Submits myjob to request 4 processors running on 2 hosts of type LINUX (2
processors per host), or a single host of type SGI, or for other host types, the
predefined maximum job slot limit in lsb.hosts (MXJ).
% bsub -n 16 -R "type==any same[type] span[ptile='!',HP:8,SGI:8,LINUX:2]" myjob
Submits myjob to request 16 processors on 2 hosts of type HP or SGI (8
processors per hosts), or on 8 hosts of type LINUX (2 processors per host), or
the predefined maximum job slot limit in lsb.hosts (MXJ) for other host
types.
% bsub -n 4 -R "same[model] span[ptile='!',PC1133:4,PC233:2]" myjob
Submits myjob to request a single host of model PC1133 (4 processors), or 2
hosts of model PC233 (2 processors per host), or the predefined maximum job
slot limit in lsb.hosts (MXJ) for other host models.
Specifying parallel job locality at the queue level
The queue may also define the locality for parallel jobs using the RES_REQ
parameter.
