Hi! I am running with 16 processors.
I will check how much memory is being used, but I think it was something related to the ILU implementations of PETSC. Now I am using SuperLU and it seems that I am not having this error anymore. The new error is: 0]PETSC ERROR: Caught signal number 15 Terminate: Somet process (or the batch system) has told this process to end [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]PETSCERROR: 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.
