[petsc-users] Lookup error in PetscTableFind()

Thu Oct 30 09:21:39 CDT 2014

Sorry for the late reply, it took longer than I thought.
So a little update on my situation:
I have to use a custom version of valgrind on CETUS which has to be 
linked to my code using -Wl,-e,_start_valgrind at compilation (I also 
add object file and libraries).
After that I can run my code with the following arguments:

    feap
    --ignore-ranges=0x4000000000000-0x4063000000000,0x003fdc0000000-0x003fe00000000
    --suppressions=/soft/perftools/valgrind/cnk-baseline.supp

but I can't use the usual petsc argument (-ksp_type -pc_type ...) since 
valgrind does not recognize them.
So I decided to use the PETSC_OPTIONS='-ksp_type preonly -pc_type lu 
-pc_factor_mat_solver_package mumps -ksp_diagonal_scale', to pass my 
arguments to PETSc.
However I am a little worried that Petsc still receive the command line 
arguments that are used by valgrind since I get the following stderr 
from valgrind:

stderr[0]: Note: see also the FAQ in the source distribution.
stderr[0]: It contains workarounds to several common problems.
stderr[0]: In particular, if Valgrind aborted or crashed after
stderr[0]: identifying problems in your program, there's a good chance
stderr[0]: that fixing those problems will prevent Valgrind aborting or
stderr[0]: crashing, especially if it happened in m_mallocfree.c.
stderr[0]:
stderr[0]: If that doesn't help, please report this bug to: www.valgrind.org
stderr[0]:
stderr[0]: In the bug report, send all the above text, the valgrind
stderr[0]: version, and what OS and version you are using.  Thank
stderr[0]: s.
stderr[0]:

I am only showing the output of rank[0] but it seems that all ranks have 
about the same error message.
Since my problem happens in petscinitialize I have little possibilities 
to check what's wrong...
Any ideas?

Best,
Luc
