Hello, I am solving a PDE where I have the spacial derivtive of the time derivative of a variable. In the DMDATSSetIFunctionLocal function I defined d(dY/dt)/dx as: (aYdot[j][i+1].p-aYdot[j][i-1].p)/(2.0*user->hx)
on my workstation, it is working but on the cluster it gives an error. I can not run with debugger on the cluster but I have checked and the error is related to this part and I do not have any problem on cluster when running in series. Can you please help me about it. the error is: 0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range [0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger [0]PETSC ERROR: or see http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind [0]PETSC ERROR: or try http://valgrind.org on GNU/linux and Apple Mac OS X to find memory corruption errors [0]PETSC ERROR: likely location of problem given in stack below [0]PETSC ERROR: --------------------- Stack Frames ------------------------------------ [0]PETSC ERROR: Note: The EXACT line numbers in the stack are not available, [0]PETSC ERROR: INSTEAD the line number of the start of the function [0]PETSC ERROR: is given.
