#BSUB Usage
If you are writing a jobscript for an LSF batch system, the magic cookie is "#BSUB". To use it, start a new line in your script with "#BSUB". Following that, you can put one of the parameters shown below, where the word written in <...> should be replaced with a value.
Basic settings:
| Parameter | Function |
| -J <name> | job name |
| -o <path> | path to the file where the job output is written |
| -e <path> | path to the file for the job error output (if not set, it will be written to output file as well) |
Requesting resources:
| Parameter | Function | Default |
| -W <runlimit> | runtime limit in the format [hour:]minute; once the time specified is up, the job will be killed by the scheduler | 00:15 |
| -M <memlimit> | memory limit per process in MB | 512 |
| -S <stacklimit> | limit of stack size per process in MB | 10 |
Parallel programming (read more here):
| Parameter | Function |
| -a openmp | start a parallel job for a shared-memory system |
| -n <num_threads> | number of threads to execute OpenMP application with |
| -a openmpi | start a parallel job for a distributed-memory system |
| -n <num_procs> | number of processes to execute MPI application with |
