Thanks, but is there any way to check if the package is already installed? My problem is that I run the PETSc installation someone already set up and I don't have the access to change it. I have tried running ./configure --help in the directory PETSc is installed, but it just reports the error because I don't have the access permition. Also, sorry I didn't understand, are the directives in the code enough or do I have to run my mpiexec command with additional options?
