Dear all,<br>
I am currently writing a code and try to combine PETSc and OpenMP (where PETSc will be used inside a parallel environment).<br>
My questions now are:<br>
1. Is it safe to combine these libraries?<br>
2. What will I have to consider to make my code work reliably?</blockquote><div><br>The main problem will be thread safety. We do not claim to be thread-safe, as we occasionally<br>use static variables. However, we try to minimize this. I think most of the uses are in output
<br>routines. You will also need a thread safe MPI (or use MPIUNI). We have tried this in the past,<br>and never really gotten any benefit from doing it. What is your target application?<br><br> Thanks,<br><br> Matt
