How to stop direct running of executable

Dear Sir,

I am using CentOS-5.2(64-bit) as an server side OS in a cluster with 32 slaves+1 Master. My question is, after compiling a file with ifort, I am suppose to get a executable(say a.out). I want my users to do ssh slave.local and then do ./a.out
But is it possible to restrict users launch the job(i.e. ./a.out in master node) directly in the master node?
If users fires job in master node, then at times the master node gets crashed. The reason is, the jobs are high end computational codes that may run for a month!
Can you please guide me to the procedures of disabling the direct launch of job in master node?
Thanks
