确定脚本是否在SGE中运行

When a Sun Grid Engine job is run, a number of variables are preset into the
job’s script environment, as listed below.

SGE_ROOT - The Sun Grid Engine root directory as set for sge_execd before
   start-up or the default /usr/SGE
SGE_CELL - The Sun Grid Engine cell in which the job executes
SGE_JOB_SPOOL_DIR - The directory used by sge_shepherd(8) to store jobrelated
   data during job execution
