LM4112 Member Luca Join Date: Mar 2013 Posts: 59 Rep Power: 13	Dear all, I'm trying to ran a DES simulation using a model with 30 million cells. I'm using a cluster with 6 processors 12 cores each one. I have noticed that there is a big difference between clockTime and executionTime ExecutionTime = 164.45 s ClockTime = 1000 s I've used the scotch method to decompose the domain. Furthermore the system uses infiniband so I don't think it's a connection problem. Anyone can help me? thank you best regards Luca
