[petsc-dev] Statistics on the popularity of PETSc

[Jacob Faibussowitsch]

Actually this reminds me speaking of package managers, do any of the HPC machines that have petsc modules installed collect any similar analytics? I can’t imagine they don’t internally keep track of this stuff (at least internally) to keep their list of available modules relevant.

Best regards,
