I receive the following errors from valgrind.

and this error repeats itself over and over again. I don't understand why PetscInitialize would give me a hard time. It's one of the first things I call in my main.c file after I initialize ints and doubles and etc.
PetscInitialize(&argc, &argv, NULL, NULL);
SlepcInitialize(&argc, &argv, NULL, NULL);
PetscViewerPushFormat(PETSC_VIEWER_STDOUT_SELF, PETSC_VIEWER_ASCII_MATLAB);
Are these just false errors? Any help would be greatly appreciated. Getting a little desperate about this. Thank you.
There are discussions here.
It seems that you use Open MPI which is noisy under valgrind. You can try to compiler two versions of PETSc (so two different PETS_ARCHs): one uses the optimized MPI in your system, and another is built using MPICH with the configure option --download-mpich.
For debugging, you can select the PETSC_ARCH compiled with mpich. For performance evaluation, you can select another PETSC_ARCH compiled with optimized MPI of your platform.
Additionaly, if you want to use both PETSc and SLEPc, you can select either PetscInitialize or SlepcInitialize for start their environment. It makes no sense to repeat two times.
I hope it's helpful for you.
