Handle input and output files

LSF provides methods for coordinating individual input and output files for the multiple jobs that are created when submitting a job array. These methods require your input files to be prepared uniformly. To accommodate an executable that uses standard input and standard output, LSF provides runtime variables (%I and %J) that are expanded at runtime. To accommodate an executable that reads command-line arguments, LSF provides an environment variable (LSB_JOBINDEX) that is set in the execution environment.
