Hi PETSc users/developers, I am having some difficulties with the -log_history option on example PETSc codes at my local installation (FYI: Cray XT architecture). When executing the ex2.c code (for example) on multiple processors with the -log_history option I keep getting:
Signal number 11 SEGV: Segmentation Violation, probably memory access out of range The log history file is created though but contains the following: Petsc Release Version 2.3.3, Patch 3, Fri Jun 15 16:51:25 CDT 2007 HG revision: f051789beadcd36f77fb6111d20225e26ed7cc0d Wed Feb 27 10:35:55 2008 [8191]PETSC ERROR: [18945200]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [59]PETSC ER ROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [ 23118368]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [118163408]PETSC ERROR: [19014780]PETSC ERROR: Without the -log_history option the code runs as expected. Is this a build/architecture issue at my end? Thanks in advance for any advice given.
