<div dir="ltr">Ah. I think I have confused you guys. I am using the most recent version pf Petsc (ie. 2.3.3 p13). I am trying to get my old code (which I made using 2.0.22) up and running. I have updated most everything and I am trying to run for the first time. Given what you said, I am guessing that I have messed up in a way the causes KSPRegisterAll and KSPRegister not to be called. <br>

</div>There is not really a "usage". They are supposed to be called automatically<br>
and you never know. However, when using ancient versions of petsc, sometimes<br>
things go wrong. I really encourage upgrading to the latest version.<br>
<br>
Thanks,<br>
