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.  
               is  pending  the  job will receive a SIGUSR1 several  
seconds before
               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  
configuration (see

               Note,  that  the  Linux operating system "misuses" the  
user signals
               SIGUSR1 and SIGUSR2 in its current Posix thread  
implementation. You
               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.
