In sge the -notify is explained as follows:
Available for qsub, qsh, qrsh, qlogin and qalter only.
This flag, when set causes Grid Engine to send
"warning" signals to
a running job prior to sending the signals themselves.
If a SIGSTOP
is pending the job will receive a SIGUSR1 several
the SIGSTOP. If a SIGKILL is pending the job will
receive a SIGUSR2
several seconds before the SIGKILL. The amount of
time delay is
controlled by the notify parameter in each queue
Note, that the Linux operating system "misuses" the
SIGUSR1 and SIGUSR2 in its current Posix thread
might not want to use the -notify option if
you are running
threaded applications in your jobs under Linux.
Qalter allows changing this option even while the job
and the users want to know if this feature is available in torque/
maui and if so how do they use it.
