Hi<br><br>&nbsp; I am trying to setup SGE to run DLPOLY compiled with mpif90 (OpenMPI 1.2b2, pathscale Fortran compilers and gcc c/c++). In general I am much more luckier running DLPOLY interactively then using SGE. The error that I got is: Signal:7 
info.si_errno:0(Success) si_code:2()[1]. A previous message in the list[2], says that this is more likely to be a configuration problem. But what kind of configuration? It is in the run time?<br><br>&nbsp; Another error that I got sometimes is related with &quot;writev&quot;[3]  But this is pretty rare. 
<br><br>&nbsp; My network is Gigabit, OS is Red Hat EL 4 the nodes are dual core Opteron 275 (4 cores). I did not use any (except for prefix) option during the configuration process<br><br>&nbsp; Any suggestion?<br><br>&nbsp; Thanks<br>
