<br clear="all">That is perfectly understandable. I am hoping to get started with sieve, so if there is a better starting point please do let me know. Andy was kind enough to provide the Sieve intro slides which made the terminology much clearer.<br>

Sorry Yaakoub,<div><br></div><div> All the examples are indeed broken, which shows how many people use them.</div><div>I will fix them on the weekend. The problem is that the main Sieve users (PyLith,</div><div>Blaise, PetFMM) required changes, and do not use any of the examples.</div>

I only managed to get the watson example to compile but it segfaults when I run it. All others refuse to compile with varying errors ranging from missing header files to:<div>
