The bsub project is a simple system to allow jobs to be submitted to batch from Java. The current system is very simple minded, it allows a job to be created anywhere, and submitted via RMI to a server which submits the jobs to LSF.

The server is permanently running on glast02 glast-jobcontrol01 under user glast. It is installed in ~glast/bsub.

The log file is currently written to into the /u1/tmp/bsub directory.
Care and maintainance
The server has been running for many months with no problems, so no problems are anticipated.
