Kill jobs
The bkill command cancels pending batch jobs and sends signals to running jobs. By default, on UNIX, bkill sends the SIGKILL signal to running jobs.
Before SIGKILL is sent, SIGINT and SIGTERM are sent to give the job a chance to catch the signals and clean up. The signals are forwarded from mbatchd to sbatchd. sbatchd waits for the job to exit before reporting the status. Because of these delays, for a short period of time after the bkill command has been issued, bjobs may still report that the job is running.
On Windows, job control messages replace the SIGINT and SIGTERM signals, and termination is implemented by the TerminateProcess() system call.
