Perhaps use 'linear, nonlinear, and time-dependent' instead of 'algebraic'?

"PETSc, pronounced PET-see (the S is silent), is a suite of data structures and routines for the scalable (parallel) solution of scientific applications that require algebraic solvers. Many such applications are systems that are modeled by partial differential equations (PDEs). PETSc may also be used with many systems that are modeled using systems of algebraic equations that do not arise from PDEs." ?

One potential user was confused by the first line on our webpage. He is working on Power Grid simulation (hence no PDEs) and assumed that PETSc is only for solving PDEs. "PETSc, pronounced PET-see (the S is silent), is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations." Hence, i think this line should be edited to make it clear that PETSc can be used for other applications too and not PDEs only. "PETSc, pronounced PET-see (the S is silent), is a suite of data structures and routines for the scalable (parallel) solution of scientific applications, and ideally suited for those modeled by partial differential equations." or something of that sort.

This was probably put up by Jin Chen (a PETSc interface developer). She would probably fix this for you, just tell her what to do (exactly what to do!). This is very old (2006), I doubt she even works with this anymore so she might just prefer to nuke it.
