Even without the specific queue, i.e., using the freely available queue, I can split my simulation and submit it to the cluster. But the problem with the freely available queue is the simulations are likely to be killed if the simulations are longer and sometimes even the smaller simulation jobs could get killed when all other queues consumed the resources. So, <span style="font-family: Arial, Helvetica, sans-serif;">I want to utilize the </span><span data-markjs="true" class="ydp75ac0da7markovdsx86sr" data-ogac="" data-ogab="" data-ogsc="" data-ogsb="" style="margin: 0px; padding: 0px; border: 0px; font-stretch: inherit; line-height: inherit; font-family: Arial, Helvetica, sans-serif; vertical-align: baseline;">checkpointing</span><span style="font-family: Arial, Helvetica, sans-serif;"> and restarting functionality of SGE to the killed job based on its job id (or some other parameter), so that I could complete a simulation without investing in node purchase.
