Petsc configure error

[Ryan Yan]

 Hi Satish,
What I am tring to do is using TAU to profile a solver using PETSc  function
calls on a Sicortex cluster. Now I am just building on a desktop.

I tried tauex, it can run. But it did not provide me any explicit profiling
about PETSc function calls. Instead, it only gave me profiling on the TAU
application and MPI routines.

I have send email inquiries to TAU developer. They suggestted me rebuild
PETSc with TAU if I want those profiles on PETSc function calls.

Frankly, I do not have experience with profiling or performance analysis on
a solver.  Do you have any suggestion or pointers to other source on doing
performance analysis for PETSc solvers, considering the option of using TAU
may need lots of workarounds when I rebuilt PETSC with TAU on the cluster.

Thank you very much,

Yan
