When I run on a given node, either the headnode, or a slave node, as long as the machinefile only has that same node in the file (i.e. ssh to “c302” and have the machines file only have “c302” listed), I get no problems at all and the code runs to completion just fine. If I try to run across any nodes though, I get a crashing error that is given below. I think the error may even be some architectural setup, but I’m fairly stuck regarding continued debugging. I ran the code using the “ddd” debugger through and it crashes on the first line of the program on the cross node (it’s a fortran program, and crashes on the first line simply naming the program … ‘program laplace’), and crashes on the first “step” in the ddd debugger in the window pertaining to the instance running on the headnode, which spawned the mpiexec job, saying:<o:p></o:p></p><p class=MsoNormalCxSpMiddle style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Verdana","sans-serif";color:#1F497D;background:white'><o:p> </o:p></span></p><p class=MsoNormalCxSpMiddle style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Verdana","sans-serif";color:#1F497D;background:white'>Program received signal SIGINT, Interrupt.</span><span style='font-size:9.0pt;font-family:"Verdana","sans-serif";color:black;background:white'><o:p></o:p></span></p><p class=MsoNormalCxSpMiddle style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Verdana","sans-serif";color:#1F497D;background:white'>0x00002aaaaaee4920 in __read_nocancel () from /lib64/libpthread.so.0</span><span style='font-size:9.0pt;font-family:"Verdana","sans-serif";color:black;background:white'><o:p></o:p></span></p><p class=MsoNormalCxSpMiddle style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-family:"Verdana","sans-serif";color:#1F497D;background:white'>(gdb) step</span><span style='font-size:9.0pt;font-family:"Verdana","sans-serif";color:black;background:white'><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’ve pretty well exhausted my troubleshooting on this, and any help would be greatly appreciated.
