[petsc-users] Configuring without debug

[Bojan Niceno]

Sorry for this post, I figured out myself what was I doing wrong.

I was configuring for compilation without debugging, but my PETSC_ARCH 
variable was still set to arch-linux2-c-debug :-(

I have the optimized version running as I write this message.


     Cheers,


     Bojan
