So far, the users who use SGE submit via qsub (most of our programs are compiled with MPICH2). Those who didn't use the SGE, made a list of 'hot nodes' and put them in machinefile. then submitted their jobs via mpirun The cluster has the following programs installed on it: # Crystal 2003 | 2006 | 2009 # DMol3 # Gaussian 1998 | 2003 | 2009 # NAMD 2.8 # Quantum Espresso 4.2.1 # SIESTA 1.3-f1p | 2.0.1 # SMEAGOL 1.0b # VASP 4.6.28 | 4.6.31 | 5.2.2 and they have been behaving well with SGE so far. How would I tighten up the SSH screws so that their jobs will run but won't be able to log into compute nodes? Is it via /etc/ssh/sshd_config or some other such file? Please let me know.
